    Looks like RT-N66U, has CPU/RAM/NAND/USB3.0 like RT-AC68U but is single-band wireless router like RT-N16. What is it? Asus RT-N18U :)


    [​IMG]

    - CPU Broadcom-ARM dual-core 800MHz (same as in RT-AC56U and RT-AC68U)
    - RAM 256MB (FSB 533MHz)
    - NAND 128MB
    - Gigabit switch
    - 1x USB2.0 + 1x USB3.0
    - 3x external antennas
    - 2,4GHz radio N600 (single band router)

    i finished Tomato for this nice router :) Support will be added to Tomato in v121.

    Best Regards.

    Very nice feature of the router, and great potential.... still don´t available on amazon or ebay yet. If it supported by tomato, then it´s a good choise.

    I imagine it'd be around an RT-N16, since they're targeting similar consumers. However the N18U isn't available in the US so I've got no idea.

    Anybody tested the USB speeds on this router?
    What is the max speed with SAMBA and FTP? (ext; Tomato)

    Thanks.
     
  13. shibby20

    same as on RT-AC56U and RT-AC68U (the same CPU).

    ~24MB/s via Samba (both way).

    ummmmmm, thats more then AC-56U (scratches head)
     
  16. Monk E. Boy

    Monk E. Boy Network Guru Member

    That's because it's not sold by Amazon for that price, it's sold by a third party who advertises their products through Amazon's website. Amazon has become the equivalent of eBay, much of what's for sale on their site isn't actually sold by Amazon, it's just advertised there by third party sellers.

    These RT-N18Us are apparently being sold by someone who bought a few units overseas and is trying to turn them them around for a tremendous profit because, well, he's an idiot.

    Right, that price is not real. I asked Asus who confirmed me that it will be sold for about $100, from August.

    ~$100 is a good price for this router IMO.

    Which would make it a direct replacement for the RT-N16 (pretty similar pricing).

    Hopefully it will be sold worldwide and not just for some specific markets.

    Is this router for sure dual core? I don't see anywhere on the Asus website that says it is.

    Single core according to Asuswrt's source code:

    i had to return RT-N18 to Asus few days ago well i cannot check it now. I thoght it has the same CPU as AC56/68... I should have new RT-N18 tomorrow, then i will be able to check it.

    Hello Shibby,

    Today I bought an RT-N18U and flashed with the 121 AIO package through the Asus firmware restoration tool.
    I experienced the following problems:
    -after the successful firmware upgrade the web interface and dhcp service was not worked
    -I had to set a fixed ip address and telnet into the router to make "nvram erase", after this I could reach the web interface

    Now it's working fine, but I cannot format the JFFS because I get the following message:
    "Error formatting JFFS. Check the logs to see if they contain more details about this error."

    Is JFFS available on this router?
    #update, after switching off and on the router, JFFS is working properly.

    Also tested the USB speeds on EXT4 and NTFS, both have a speed of approx. 16MB/sec, which is still quite good in this price category.

  33. ntamas26

    ntamas26 Networkin' Nut Member

    I think if you consider the price of the router it's still a quite good choice.
    Prices in Europe:
    RT-N18U 100%
    RT-N16 90-95%
    RT-N66U 160%

    This router approx. has the same USB speeds (only under NTFS, it's slower on EXT3/4) as the RT-N66U, and it has better performance compared to the RT-N16. (256MB vs. 128MB memory, 64K NVRAM)
    So if you do not need the 5GHz and at AC support, it's not bad.


    First experiences with Tomato 121 on this router:
    -CPU Load (1 / 5 / 15 mins) not working properly because it always above 2.00 regardless whether the router is in idle state. I guess this is because it was believed to be a dual core version.

    -USB speeds: it's a bit weird for me, that under NTFS this router is faster than on EXT3/EXT4. Maybe the Paragon NTFS driver has a better implementation on ARM than the stock linux EXT drivers?

    -JFFS is working properly, but when you format it you'll get an error message at the end of the operation. Then you need to shut down the router, after it'll be reachable.

    -Boot time is a bit longer than on RT-N16.

    -After flashing RT-N18U with the Asus Restoration Tool, the Tomato webadmin is not reachable for me (I flashed 4 routers for friends) so first you need to SSH (putty) into the router and do an:
    -nvram erase
    -reboot

    Then you'll be able to access the webadmin where it still recommended to do an other nvram clear:
    administration/configuration/restore default configuration/erase all data in nvram memory

    Mad_Clown LI Guru Member

    Since the RT-AC56U is only about $120, it seems like $100 for the RT-N18U might be a little expensive.

    It would be good to integrate stealth mode for RT-N18U too.

    Some LED keys which can be useful for that.
    Switch Off / Switch On led:

    Power led: gpio enable 0 / gpio disable 0
    USB 2.0 led: gpio enable 3 / gpio disable 3
    WAN connection led: gpio enable 6 / gpio disable 6
    Wireless led: wl -i eth1 leddc 1 / wl -i eth1 leddc 0

    In China:

    Netgear R7000: a few days ago, special price, 799RMB(~130USD)

    Which one do you prefer? LOL

  40. ntamas26

    ntamas26 Networkin' Nut Member

    Weird because here in Europe/Hungary it costs about 86USD, and we usually have way worse price compared to the US. Maybe Asus targeted this router to Europe?

    Nobody has montioned about wi-fi beamforming /airadar/ in tomato builds for rt n18 u. As I have tested think that stock firmware has better coverage/used wi-fi analyzer/.my old router is rt n16 and has no difference in coverage.
     
  49. sysop82

    sysop82 Network Newbie Member

    Does anyone have some info on this router if it will be sold in the USA anytime soon? I just bought a RT-N66U which is very much to my liking. However I'm wondering if the 18u would be better for me. I live in a residential area with only one other network near me so the 2.4 isn't cluttered. I don't really need the 5ghz radio of the 66u.

    The 18u seems to have better hardware with 800 cpu and more flash and ddr3 memory. If I don't really need the 5ghz radio would anyone recommend I return the n66u and look online for the 18u? I am only seeing it sold on eBay right now I would have to import it from China to usa.

    Would this be capable of ~150mbp download speed with Tomato and some basic QoS?

    I've been using Tomato with a WRT54GL for many years, it kicks major butt. Unfortunately, it can't handle my new internet plan (getting about 40mbps in SpeedTest).

    Don't care about WiFi speeds at all, as long as it works. So lack of expensive 5 GHz is a plus for me.

    And I really don't want to leave Tomato :)

    Chadrew, right now, they are going for about $120 US on ebay. You will need to buy your own AC adaptor that provides 12V DC 1.5A output, since they are not being sold in North America. I just made the jump and bought one. I just installed tomato so I can't really attest to its performance just yet.

    The LAN led is not coming on even though I have LAN cables connected and working, is anyone else experiencing this? Also, to perform a hard reset, am I supposed to press and hold the WPS button instead of the reset button (like I had to do with the RT-N16)?
     
  52. heraldo

    heraldo Network Newbie Member

    Hey, LAN lights are not working on mine either, I flashed with tomato-RT-N18U-ARM--123-AIO-64K.
    However, I do not remember if they were working with Asus fw either :p

    I had to press and hold the WPS button to get the router up and running after flashing.
     
  53. Monk E. Boy

    Monk E. Boy Network Guru Member

    When you press and hold the WPS button while applying power (the power light should start blinking rapidly) it erases the NVRAM. If the NVRAM contains values that stops Tomato from loading, erasing NVRAM is certainly a good idea.

    You should also be able to enter recovery mode by holding the reset button, then visit the recovery website (192.168.0.1 or 192.168.1.1), which on newer routers should give you three options: upload a new firmware, erase NVRAM, and reboot the router. The erase NVRAM option typically doesn't force the router to reboot (at least not on the models I've seen that list it), so you can wipe NVRAM prior to uploading a new firmware.

    I wonder if ASUS is ever going to officially release this unit in the US?
     
  54. RMerlin

    RMerlin Network Guru Member

    I asked someone at Asus about two weeks ago. He said he'd get back to me on it, but so far no answer.

    I know that person was recently taking extended leaves from work for personal reasons, so it's possible is again on a leave of absence. In any case if I ever hear back from Asus I'll let everyone know.

    rt-n18u.jpg

    Ended up getting it today. It works very well, but what did I expect, my internet is only ~120mbps download. This router is too powerful for it :)

    I haven't experimented with Tomato yet, but I noticed that default Asus firmware has QoS as well. Is it very bad compared to Tomato's?

    Edit: when downloading torrents at 100mbps, the CPU usage is ~40% (default firmware, no QoS), so I doubt it can torrent at 500mbps, unless I'm doing something wrong here.

    I heard back from Asus - they currently don't have any plan for a North America release of this model. That doesn't mean that can't change however, I assume they might change their mind if there's enough demand.
     
  57. maurer

    maurer LI Guru Member

    would this be fine for 500/100 mbps PPPoE connection?
    i would need to support this high bandwidth of connection only for torrents...
    my RT-N16 running rmerlin can only go as high as 150mbps on torrents although speedtest can go to almost maximum 480 mbps DL
     
  58. RMerlin

    RMerlin Network Guru Member

    For such high speed you need Hardware acceleration (CTF) to be enabled.

    The RT-N16 is limited because it's based on an old driver, which lacks HW acceleration for PPPoE connection.
     
  59. maurer

    maurer LI Guru Member

    and would rt-n18 handle CTF with tomato, as i've noticed that the're isn't a official rmerlin build ?

    In Germany that Router costs 69,99 € on Amazon.de shipping included which is 86$ US-Dollar so it 's at a better price tag then the N16 on Amazon.de :D (the only downside that I read on a comment is that it 's CPU can reach 75 °C which seems a bit ... high for me).
     
  61. RMerlin

    RMerlin Network Guru Member

    75C is perfectly fine. The RT-AC68 can hit 85C with a dual core version of that CPU.
     
  62. Toastman

    Toastman Super Moderator Staff Member Member

    Get ready for the reports of routers exploding, and users installing brick-sized heatsinks and huge fans powered by nuclear reactors ... :D

    Seriously, it does look as though it has a reasonably large passive heatsink, I wouldn't expect any overheating problems.
     
  63. Image This

    Image This Reformed Router Member

    I wonder why it does heat up so much anyway - compared to the R7000. I mean the RT-AC68 - it isn't that much smaller isn't it. My R7000 rarely hits 60 °C - thats actually 25 °C difference even though the R7000 's CPU is running at 1.000 MHz unlike the one in the AC68U.

    And then take for example the Samsung S4 Mini which uses even less space with a Dual Core ARM CPU Running at 1.7 GHZ - it 's CPU is getting as hot as 56-60 °C as well. It makes me wonder why the ones ASUS integrates are running this hot to begin with.

    Maybe it 's the way they implemented the Temp Sensor? Or where it measures the Temp?
     
  64. RMerlin

    RMerlin Network Guru Member

    The sensor is inside the CPU. I find such a large difference hard to believe myself, especially since Netgear are usually cheap on their heatsink design. Are you sure that's the CPU temperature and not the wifi radio temperature (which has its own separate sensor)?

    Over SSH/telnet, you can manually read the CPU temperature this way:

    Code:
    admin@Stargate87:/tmp/home/root# cat /proc/dmu/temperature 
    CPU temperature    : 75øC
    
    (This is my RT-AC87U)
     
  65. Image This

    Image This Reformed Router Member

    [​IMG]

    cat /proc/dmu/temperature is reporting 569 for me which falls in line with the backend display of 56.9 °C

    The CPU-Temps of the R7000 similiar to that of modern Smartphones with a similiar type of ARM CPUs like the S4 Mini so I'd say it 's more likely the AC68U CPU Temps that are way to high especially when compared to a Smartphone - which is way more compact and is running at 2x1.4 GHZ with 60 °C reported.

    Other users report the same Temps for their R7000 (a bit higher then mine tought not much - mine is wall mounted upside down dunno if that helps especially or if I was just lucky with the device):

    http://www.dd-wrt.com/phpBB2/viewtopic.php?p=788972

    and even @1.4GHZ OC: http://forum1.netgear.com/showpost.php?p=476026&postcount=144

    Edit: Forgot to add - to the touch its also very cool way cooler then the AC66U or N66U

    shibby's new firmware add support to D-Link DIR868L
    BCM4708+GigE+AC1750
    In China, costs RMB700(~114USD) including free shipping. In the meanwhile, N18U costs RMB650(~106USD).
    Although I have a very bad impression about D-link (their firmware sucks), but with Shibby's new firmware support, I have no reason to buy N18U now (unless this time DIR868L's hardware sucks).
     
  68. shibby20

    shibby20 Network Guru Member

    DIR868L has one big issue. It support only 32KB of NVRAM!! If you will try store more then you will brick your router. Only chance to revive then is serial cable! Please remember that! This is why for this router image has name "special", because i had to remove all features which store so many variables in nvram, like: BT, openVPN, SSH etc.

    Jan 1 01:01:28 unknown kern.warn kernel: PCI: Fixing up bus 0

    I was wondering if this is related to some issues I have been experiencing with the RT-N18U firmware:


    (1. Internet connection seems to drop and come back up at random times, I am still looking into what could be the cause.)
    RESOLVED -NOT FIRMWARE RELATED

    2. Saving/Restoration of configuration files has failed me in the v1.23 and v1.24 firmware.

    3. Bandwidth monitor is not working. It was not working in v1.23 either.


    Thanks,

    Hi, to everybody!
    Please help me. I've followed many guires for use WIRELESS CLIENT, or REPEATER CLIENT with last DD-WRT and Tomato. From an AP without tomato or mods and my new RT-N18U used as wireless client, and I can do that if security is set to Open or WEP. When I change wireless security to Wpa or Wpa2 tkip or aes or any mix from those I can't establish connections. From the page thath show the clients connected to the AP I can verify that the Mac address of the client rt-n18u appears for 3 second then disappear and in loop appears again after 3 second and then disappear....
    The stock Asus firmware can connect in repeater mode to my AP with wpa2 aes wireless security key.
    Any suggestion? Thanks

    What happens to my L7 QOS Classification Rules if I disable the check box on the conntrack/netfilter page? I ask because it says inbound, does that mean that outbound connections (thinking skype, ventrillo, flash) still get some benefit?

    I had to wait quite long until this nice router was available here in Switzerland. I've spoted it a few weeks ago on the website of my preferred dealer. Since this week, it's also available from a second place.

    I've paid 61 CHF for the router including shipping, which is a rather good price IMHO. :)

    I have already quite a few routers in my armory (RT-N66U, RT-N12 D1, WRT54GL, TL-WDR4300), but this one looks still very attractive to me. My hope was to get a capable router which draws less power and generates less heat than for example the RT-N66U. I've measured around 8W idle and temperature of the case seems acceptable.

    I'm running Tomato K26ARM 129 with it at the moment. The only (cosmetical) issue so far is the LAN LED, which doesn't seem to work. I use most of my wireless routers as APs or wireless ethernet bridges since I prefer usually a pfSense based firewall/router, therefore I did not test every available feature. Maybe this will change somewhen, because I have plans for a partially mobile setup with a 3G USB modem.

    Many thanks to Shibby and everyone else involved in creating the great Tomato firmware.

    That's a good price indeed, even more so for CH. Would it be possible to test the WAN/LAN performance - I've been looking at this router for a while but I'm not clear how well it will do with a gigabit (PPPoE even) internet.

    Thanks,

    It will be hardly possible for me in the next 3-4 weeks to do thorough tests with the RT-N18U. The main reason for this is my participation at a validation for further education in IT. It's no priority for me at the moment.

    Personally, I don't think the RT-N18U is an optimal choice for Gb-class WAN. I've spoted a thread from you on the forum which discusses the same question, although in a generalised form. I agree with some of the posts in this thread: IMHO a x86-based firewall/router will be a much better choice for a WAN connection at Gigabit speed. In your case, I'd use a RT-N18U as AP together with an x86-based firewall/router solution.

    http://linksysinfo.org/index.php?threads/recommended-router-for-wired-1gbps-pppoe-internet.71320/

    I have only a VDSL connection at home and I'm using also a x86-based firewall/router with that connection. I'm using pfSense and I use a Squid proxy on that firewall/router, which is a quite noticeable acceleration. The used hardware is a Shuttle DS47 (with two awful Realtek NICs, but this makes absolutely NO difference for VDSL). Shuttle has released a successor for the DS47, which uses two intel NICs and is called DS57U. If you can live with two NICs, then it could be a very good choice with a lot more horsepower than for example a PC-Engines APU.

    A friend has symmetric 1Gb/s FTTH at home since a couple of weeks, which is NOT using PPPoE. We use only a media converter to connect it to a x86-based firewall/router using pfSense. We've choosen quite capable hardware for this (i3-4130T, 8GB RAM, fast SSD, only intel Gbit-NICs). Idle power consumption of this firewall is around 28W, which isn't bad IMHO. The solution may looks a bit oversized, but it should also offer an upgrade path to 10 Gb/s Ethernet in the future. The used mini-GBIC for the FTTH connection is rated for 25 Gb/s BTW. The CPU supports also AES-NI, which is supported by pfSense.

    I've noticed that my RT-N18U does need quite a long time for booting. I didn't measure the time, but it takes definitely longer than a RT-N12 D1. Unfortuately, I can't compare with my RT-N66U at the moment because it is used now and sits on top of the 27HE rack.

    Has anybody else noticed this behaviour also? Is it somewhat related to the ARM architecture? It's no problem for me and the router works fine beside of that. BTW: I'm using Tomato-Shibby K26ARM 129 AIO with it.

    It's not that bad, it's about 45s floor on my R7000. To shutdown however it takes about 35s, which really trips up the flashing process.

    There's definitely optimizations somewhere ;)
     
  90. uridium64

    uridium64 Connected Client Member

    I've measured it now on the RT-N18U: It takes 2 minutes and 39 seconds until the WLAN LED lights up after a cold boot. The router is not accessible on the web GUI until the WLAN LED is on. Reboot takes even more time, obviously because it has to shutdown first. Time for shutdown is in the range I'm used to with other Tomato routers (mostly ASUS in my case).

    Yes. I really like the RT-N18U and it has great potential. But so far, I'll consider it still "being in development", which is not meant in a negative way. I've read enough about the ARM-builds to know that these builds are not as mature as MIPS-builds at the moment. For the daily work, I'm using still MIPS-based Tomato routers, which work very stable.

    Today, the radio of the RT-N18U has stopped for the first time after only about 10-15 hours uptime. Never had the problem before but users of other ARM-based routers have reported this behaviour also. The router was still working fine in the web GUI, when the radio "disappeared" (it was not visible anymore and clients) and it was still possible to use the wireless survey. It was necessary to reboot the router to make the radio work again.

    Maybe it's a good idea to change Tomato-Shibby K26ARM 129 AIO to Tomato-Shibby K26ARM 129 VPN. The smaller image offers still all the features I need and I wouldn't be suprised to see improvements regarding performance and the time needed to boot up.

    Compared with for example a R7000 or RT-AC68U, the RT-N18U has only (approx.) half as much CPU performance, but this alone doesn't explain the difference in time needed to boot up. 2:39m compared to 0:45m is more than 3.5x slower.

    I'll give your builds also a try, because the improvements in your builds have not been implemented in the Shibby-builds until now, if I understand it correctly (based on the thread linked below):

    http://linksysinfo.org/index.php?threads/tomato-arm-builds-w-inbound-qos.71285/

    BTW: Is there a way to send you a donation for your great work?
     
  92. uridium64

    uridium64 Connected Client Member

    I've noticed that the wireless of my RT-N18U disappeared again shortly after todays reboot. Maybe an accidential power loss yesterday (I've disconnected the mains cable of the used powerstrip accidentially) has a relation to this problem. Perhaps the firmware on the router was damaged by this. Before that, the router was running for a few days without problems, at least the radio was always visible on my clients.

    I used the opportunity to flash Tomato-Shibby K26ARM 129 VPN on the RT-N18U. The NVRAM was also cleared and I measured the time for booting up again. Now, it's 2 minutes and 23 seconds. The used image seems to have only a rather small influence.

    As a side note, it looks like price-wise, AC56U is starting to be on the same level as N18U - not always but the discounts for AC56U have started to be fairly big (I presume because it's somewhat old and probably out of production) while N18 is still fairly new and the price sticks.
    Between the two, AC56 has definitely more potential, has AC support and further more is better supported - N18 is only available in EU.

    Long story short, I'm not sure what ASUS plan is but with current pricing and specs, there are better deals than N18...
     
  94. uridium64

    uridium64 Connected Client Member

    I'm able to buy the RT-N18U very cheap in Switzerland (also in comparison to other countries). I've paid 61 CHF with shipping included for the RT-N18U, while I'd have to pay approx. 95 CHF for the RT-AC56U. For a few bucks more, I can buy also a RT-N66U. The RT-AC56U certainly is a nice router and it has partially better specs than RT-N18U (2x the CPU horsepower, 5 GHz radio), while the RT-N18U is superior with its 2.4 GHz performance and uses slightly less power. Personally, I also do not like the internal antennas of the RT-AC56U. External, detachable antennas are an advantage in my opinion and make a WLAN router more versatile. But this is a personal preference.

    Since prices vary depending on the country the router is sold and older models often get cheaper, there is no final answer IMO. A decision for a router should be based on the "bang-for-the-buck" a router gives you and on your personal needs, which can also vary greatly depending on the application.

    BTW: Switerland is NOT in the EU and I can get the RT-N18U here. When the sale of this router is geographically limited, then it's more a limitaton to (continental?) Europe. Are there any owners of RT-N18U from UK, North America, Asia or elsewhere?

Interestingly, the RT-N18U does not appear on the official Asus web page for the UK. https://www.asus.com/uk/Networking/AllProducts/ Whether it is on sale in the UK is another matter, since EU rules allow for the free movement of goods with the EU zone, but officially Asus don't list it.

    Norway is in Europe but not part of the EU. (It is part of EFTA, as is Switzerland.) Asus lists the RT-N18U on its web site for Norway: https://www.asus.com/no/Networking/RTN18U/

    Hello,
    I searched in the internet but cannot find a instruction how to perform a hard reset specifically for this router. Yesterday I flashed several firmwares (Shibby and Toastman's build) and found that I cannot change the WiFi channel anymore in B/G mixed mode. It stays on channel 1 even if I select channel 11. So I would like to clean up everything to flash again a firmware.

    Using the ASUS restoration tool also didn't solve the issue.

    Thx!

    So, meanwhile I found a NVRAM reset instruction for the RT-N66U which seems to work also for the RT-N18U:
    - Power off the RT-N18U
    - Press and hold down the WPS button
    - While holding the WPS button, plug in the power cable to turn RT-N18U on
    - Keep holding the WPS button for 30 seconds before releasing
    - The router should reboot

    Unfortunately my channel select issue cannot be solved with that NVRAM reset. I'm still permanently on channel 1.

    Sorry for resurrecting an old thread. Has anyone tested the WAN connection on this unit (RT-N18U) and see if it is indeed capable of speeds greater than ~15 mbps? I ask because I have a RT-N16 and finally upgraded my 15 mbps broadband to 100mbps and for whatever reason (running Shibby Tomato 1.28, and the GUI shows 1000 Full), speedtest (and Brighthouse's own speed test) tops out at 14 mbps. When I directly connect my PC to the cable modem (Arris Motorola TG1682) bypassing the RT-N16, I get 100+ mbps. Around here, the broadband is up to 300 mbps.
