Netgear R6300V2 Crashing Tomato 138

    Hello,

    I love this firmware, but my Netgear R6300V2 has been crashing. It crashes around every 6-8 hours periodically. The interruption is a few minutes, but it is still annoying. The firmware does everything I need it to do and the interface is beautiful. Are there any suggestions? I do not have QoS or any other hardware intensive settings enabled. My network is very simple. Any feedback would be greatly appreciated.

    Thanks,
    PSTO

    Do you write syslog in an external drive? If so, logs may be useful to diagnose what's going on.

    I have Netgear R6300V2 and I was running it on advance tomato 138 without any problems ...
    now is on AT 132 (i changed it because of suggestions that 132 is more stable - but I don't see any difference ... )

    I tried logging to an external USB device and there is no log data on what is causing the crash. I noticed it has to do with wifi. I had a friend connect in his apartment below mine and it crashed the router. I then tried to speedtest from my iPhone in a remote bedroom of my apartment with the door closed, this also caused a crash. In the morning when I first wake up and check email on my phone the router will crash.

    It seems to be wifi related. I lowered the transmit power from 42 to 40 on both radios and the issue is still present. Should I downgrade from 138 to 136 or another version? I am using the correct power adapter for the R6300V2. Temperatures are inline there is no other issue with the router. I can max out my internet connection for hours without the router crashing. I really want to make this work. :(

    set the country on a magical snigapur;-) transit power for 0- then the default, select the channel 2.4 wifi a little popular example 4. narrows the channel from 40 to 20 mghz then they are less interference.

    You can upload what Do you want tomato - only the aisle to 132 versions of one and the other side compulsorily - cleaning the nvram.
    If you change from 138 to 136 etc. This is the recommended cleaning nvram and entering settings finger

    I recommend you try the version 132.18 by @ kille72 it improves many mistakes version of 138 and is very stable

    Hi Pomidor,

    Thanks for the suggestions! Just so I understand, I should change the country from USA on the 2.4ghz radio to Singapore. Then change the transmit power to the default, or to "0"? Following the transmit power change, I should change the channel from "automatic" to "4"?

    If this fails, I should try 132.18 as the is a stable version, okay I got that part, but the other parts are a bit confusing. Does that completely turn off the 2.4ghz radio? Do I still get the advantage of AC1750?


    Dzienkuje,
    PSTO :)

    in toamto transmit power 0 is not zero only the default value for a given country
    the basic tab Change the channel from automatic to manual and set the example for the 4 channel in my few people using it at most to 1, 6,11,13
    reduce the width of the channel at 20MHz with 40 supposedly less bandwidth but interference for less.

    sory and 138.12 by @ kille72 should not have in your case, but since 132 not wants to work well try to get 138 amendments kille72

    My Linksys e2500v3 also crashes once or twice a day. I have WDS enabled with e2500v3 as main and a Linksys e1200v2 as secondary router. I completely solved the random rebooting by changing the encryption to WPA-AES. Before it was WPA2-AES which causes the router to crash and reboot randomly. The only router which crashes was the e2500v3 the e1200v2 was fine. Also as suggested choose Singapore and set the transmit power to 0 for better signal. Use 20mhz for 2.4ghz. If you don't use 5ghz you can disable it.

    yes of course
    when changing the firmware, preen nvram and enter settings from scratch, do not use the copy settings

    Thank you for the clarification! I am running 138 Advanced Tomato. In addition, all of my devices are connected to 5ghz, none to 2.4ghz. I have a separate network for 5ghz that everything is connected to. Should I install Advanced Tomato 132?

    no 138.12 by @kille72 this tray https://mega.nz/#F!bAcVXCSY!DgPc0zfhunujKblc1qsQ0w
    Prune just in case nvram, because as you passed the old toamto 132 to 138 miltiwan toamto cleaning is mandatory for 5ghz also set singapore, transmit power 0, and find little used channel. if you 5ghz mistake but rather, has just set the security to WPA2-AES

    Alright, guessing I need to clear all NVRAM after flashing, correct? Also, should I name the 5ghz and 2.4ghz SSID's the same and have the same password to achieve the full AC1750 speeds? I am aware that speeds will never be the 1750gbps, I wanted to be sure.

    so it's just a theory; -)

    The extremely netgaer on, he has the Asus drivers and it's not because the latest Shibby and Tostman do not have the latest,

    in terms of speed XVortex it is faster but your router I've seen somewhere in China just fork http://firmware.koolshare.cn/merlin_8wan_firmware
    XVortex a clone Rmerlina for Netgear and he has better drivers.
    Tomato is more functional for me but it is not the fastest, unfortunately,

    Have you tried different wireless encryption? like WPA-AES? that solved my router from randomly rebooting.
     
  16. psto2017

    psto2017 Network Newbie Member

    I tried all of those settings recommended above by Pomidor, I really appreciate it, but it did nothing for me. I can make the router crash by speed testing from my iPhone on wifi in my bedroom with the door closed. The router is around 15-20 feet away. This makes little sense, it is rock solid otherwise.

    I tried turning off 2.4ghz completely and only leaving 5ghz on. I changed it to Singapore with default settings. I lowered the frequency to 20mhz from 40mhz. Additionally, I set it to a channel without another AP on it.

    Any ideas? This router is identical to the R7000 which people have great reliability with.

    Forget about Singapore and stick with United States. It should work just fine.

    Also, how does the router crash? That's the reason I asked for logs. It's not that easy to crash, unless you have a defective router, a defective device attached to the router, or the system is doing something funny.

    psto2017 Network Newbie Member

    Update: I changed the country back to United States for both radios and left the transmit power setting at "0". I set the frequency to 20mhz on the 2.4ghz radio and left it at 40mhz on the 5ghz radio. I also set the Wireless Interference Mitigation to "WLAN auto" on the 2.4ghz radio. I ran a series of test and the router has not crashed. I set the channels manually to those without any other AP's. I'd like to leave this at auto as they obviously change and I do not want to constantly adjust this.
     
  20. psto2017

    psto2017 Network Newbie Member

    I tried logging to an external USB device when the router crashes it does not leave anything here that is usable. The crashing is just basically restart. The wifi light goes off, followed by a reboot, thats about all the symptoms I am aware of.

    with no goodies such as image Shibbiego is multiwana etc. but it is more stable and the interface is a standard tomato.

    AT 138.12 tried (it has an interface adanced) to kille72 is some modified version of 138

    this is just a chance to change the images in the hope of will not be errors
    I do not know what is the cause and as my previous speaker wrote logs show it can be something more to say
     
  23. psto2017

    psto2017 Network Newbie Member

    So the image you linked me to for 138.12 has the advanced interface?
     
  24. pomidor1

    pomidor1 Reformed Router Member

    yes 138.12 AT
    Rather, it will not do anything, because as I spoke my speaker repro I was looking for somewhere else to some external device, rather, because you need to copy the logs and look for logs of entries In relation some mistakes because the one who is just guessing

    Try 84mw as transmit power. I don't trust that Zero as hardware default value. I have zero issues on both spectrums.
     
  26. vancer32

    vancer32 Networkin' Nut Member

    Can you test it without any wireless encryption? Did you try different encryption like WEP WPA?
     
  27. psto2017

    psto2017 Network Newbie Member

    I actually got the router to stay up around 24 hours so far just by disabling the 2.4ghz radio. My building is hyper-saturated with 2.4ghz routers. I left everything stock on the 5ghz radio and run the 40mhz frequency. I tried multiple speed tests to get it to crash by placing the devices in remote areas of my apartment that previously caused it to crash and it no longer does. Having a friend (he can barely see the AP only in certain rooms) connect downstairs (through a 1 foot thick concrete floor) still causes a crash though, but none of my devices do.

    Question, it looks like the 5ghz radio is currently only on 802.11n, how can I get 802.11ac? On the stock firmware its automatic between 20/40/80mhz. On Tomato 80mhz crashes almost immediately and the speeds are awful. 40mhz works just fine, but like I said, this is definitely 802.11n. Tomato does not let you choose "ac" just "a,n, and auto". I tried searching around and there is little information on this. Just curious... :) Does Tomato 138 support 802.11ac?

    Yes, supports 802.11ac by default, as long you leave on Auto.

    Don't bother with range on 5Ghz. The range compared to 2.4Ghz is pretty awful.

    I use 80Mhz, and have an Archer T9E as my desktop card (which is the same chipset as the router) and works fine.

    Hmm, that works, I tried that before and it did not work correctly. I saw 1300Mbps, but its now at 702Mbps. I understand this is the speed at which other devices connect

    One thing that is strange my ping times on wifi on the LAN are between 10ms-150ms. This is really high for LAN. It was not different in 20mhz, 40mhz, or 80mhz on various 5ghz channels. Is this normal? Wired connections are around 0.35-0.50ms on LAN.

    you need to test the transmission power,
    These symptoms do may suggest the power is too large, too close, you have a phone and router so the signal can be distorted.
    Gradually reduce the power transmitted and see parts of improves ping or not

    1) I have three AC devices, so my desktop card won't negotiate at 1300mbps unless I turn off everything else.
    2) You cannot expect 1ms response for Wi-fi devices such as cellphone, tablets, and even some laptop cards...

    You absolutely cannot compare a somewhat confined physical layer (i.e. Ethernet) with a totally open and uncontrolled physical layer (i.e. Radio).

    Each wi-fi card behaves differently. Combinations of what's the transmitting SoC and receiving SoC greatly affects overall performance.

    Broadcom & Intel, a rather common combination, don't play very well regarding wi-fi performance, so you usually add 3ms to everything.

    In other hand, I see Cisco AP's performing very well with Intel cards.

    On my desktop, I have an Archer T9E, which uses exactly the same wi-fi (BCM-4360), and it is a PCI-Express card, so it can squander TX/RX power as much as it wants (It has a big heatsink because of this). so response times look like I am on cable. Less than 1ms average.

    My Intel AC card on a laptop does 3ms on average. My cellphone is a rollercoaster, and it was worse before...

    But cellphones are low-powered devices, which employs everything to lower power consumption in order to save battery, so you absolutely cannot expect cable-like performance from them, but rather something like best-effort.

    Wi-fi is a wild world. There are dozens of threads with rather lenghty posts explaining the shortcomings of 802.11 stuff and how we can get most of it.

    My way of getting most of my router, is a native and rather expensive PCI-E card, and the very best one in my opinion.

    Very interesting responses and very cool network cards. The device I did my ping tests to is a Intel NUC - NUC6i5SYK. It has the Intel 8260 M.2 802.11ac built in network adapter.

    This is a very small device, slightly larger then the size of a pack of cigarettes. I can still move files to it over wireless from my wired computer to the device at 42MB/sec which I think is pretty good for wireless. The ping times are very high though, between 1ms all the way up to 300ms, it varies.

    Quick update, I am now at a 10+ day uptime. My router has been rock solid. I just setup an identical router for my friend who lives on the floor below me. This is a really nice setup, especially considering this is a $25-30 router from eBay. I have 150mbps/20mbps internet.

    I can achieve the same speeds through the router that I would being connected directly to the modem. I am able to transfer large files from ethernet (MBP) to wireless (Intel NUC) on my local network at 50-52MB/sec, wired to wired is around 82-94MB/sec.

    The ability to assign hostnames e.g, computername.local, via the DHCP settings in Tomato is also very convenient for me.

    My settings:
    Netgear R6300v2 running Advanced Tomato 138
    No QoS or VPN services are being utilized on the router
    2.4ghz radio is turned off. It is absolutely worthless. There is too much interference in my building, additionally I've observed decreased stability.

    5ghz radio settings
    • Country set to Singapore - had stability issues with United States
    • Transmit power set to "0" - left this at default
    • 80mhz channel width - could not achieve full 802.11ac speeds at 40mhz, but had stability issues at 80mhz with United States country setting.
    • Channel 36 - this most unsaturated channel that my router and devices can see
    • WPA2-AES Encryption - no brainer
