How to squeeze +50Mbps from 1.28.121006

    Have a WRT54GL 1.1 wireless Rev9 on a 100Mbps service running
    VicTek 1.28.121006.
    Did the NVRAM erase before upgrade. Came from official Tomato 1.27.


    What can I do to get closer to 70/80Mbps out of this apart from overclocking to 250Mhz (didn't change much really) and not buying a new router?

    Isolation test direct connection achieves 70/75MBps.

    I doubt you can squeeze more. I still don't know how he even got the firmware to go that high. This is an ancient router and extremely slow processor compared to today's standards.

    Hey FGW,

    No offence but I have a hard time trusting your statement when I see posts like this:
    http://www.linksysinfo.org/forums/showthread.php?t=66123

    I mean, if you can't get the CPU detail for your own situation, then what good is the statement about not getting 80Mbps guaranteed out of 1.28.121006 from other threads I've read? Stating things like this clearly says to me that I understand how you don't understand how VicTek got more than 50Mbps.

    I would like VicTek, or someone who already has, to definately state that 80Mbps is possible and more importantly how as per the 'guarantee' I've read with this firmware version on the GL 1.1 platform.

    I can't recall seeing a benchmark showing more than about 50Mbps WAN-LAN throughput on any firmware with this vintage of hardware.

    However Victek does state on his web site the below:
    Tomato RAF 1.28.121006
    This version guarantees WAN-LAN 80Mb throughput. For WRT54GL v1.0 & V1.1. Christmas Edition
    .

    I can't recall Victek making any false claims about his firmware so I'm not saying that. It's just that I don't remember seeing any benchmarks showing this throughput. It will be interesting to see what Victek has to say. Here is a representative example of the benchmarks I can recall seeing. And unfortunately I can't test it myself since the service from my ISP doesn't provide that much throughput on the WAN side to allow a test, :sad:.

    No offense taken. Key word was "doubt". Which you or anyone else is free to correct me. As for my cpu post. I found nothing wrong with it as it was a genuine question when 2 different pages are reporting 2 different things.

    I saw the same thing and also found it confusing, just didn't post about it. Made sense after I thought about it a while but not at first glance.

    I guess...

    So simplify and put Select instead of the first selection (being 188). May be more technical than I imagine, just trying to keep it simple.

    Anyway....


    Failing to gain any advice on the 80Mbps firmware and WRT54GL v1.1, which router to replace with? I've heard a lot about:

    - ASUS RT-N16
    - Netgear WNDR3700

    Or is there a good Linksys I should consider?

    Otherwise depending on the $$$, I might just slap together an old PIII with pfsense on it.

    I modded the code by putting an extra (empty) selection first, [,],[188]. - etc. Now it should show "undefined" instead of "188". It's a quick bodge but a bit better.

    As for the router, if you use wireless, the E4200 might be of interest, the 5GHz is not presently supported by Tomato though the router works with 2.4 and some work is being done on it. Then if you wait a bit there's a version of the RT-N16 - the RT-N76U, with extra wireless bits for 5GHz due soon. If you don't use wireless the RT-N16 is good.

    Just curious, have you tried PMing Victek or posting in one of his firmware threads? He may just not have had time to read all threads and missed your post.

    I think they mean 1GB LAN. The rest of it is apparently the same spec, but different packaging, but it will be interesting to see !
     
  12. WRobertE

    No. In the following YouTube video, at around 1:15, there's a close-up of a document with specs on it next to the router and it says 32 Meg flash, 1 Gig DDR2 RAM.

    Toastman Super Moderator Staff Member Member

    WRobertE, you're right! However, with 1gig they are still claiming 300,000 connections, haven't increased it to a a million yet? - LOL.

    Curious ! However, this is surely the same product they talked about just after the RT-N16 was released, which nobody ever saw, so it's got a revamp in the meantime !

    The RT-N66U is a nice looking product design with a "sports car" look to it, particularly with the red and black color scheme on both the main unit and the antenna's and the contours on the case. And, with a gig of memory, the possibilities would be almost limitless.

    Unfortunately, I can't find any mention of this model, or the RT-N76U for that matter, on the FCC website where vendors submit their products for certification. So, I can't image it will be showing up on store shelves any time soon in the US.

    Hi, thanks for posting me the thread, Tomato 1.28.121006 gives you 80mb WAN-LAN with no problem in the following condition:
    1- Don't overclock CPU, it's proved that CPU OC don't improve Bandwidth.
    2- Keep air free ventilation on WRT54GL, In my test after 10 minutes downloading 50mb dropped to 30mb without any reason, after opening router case and check for causes I saw BCM5352 (switch manager) at 55ºC. Applying FreeZero 50mb BW was restablished.
    3- The rate is achieved with more that 5-10 threads, so, better test download using a download manager to test it accurately.

    And finally ... OC don't add any improvement to the router, on my next releases you will see OC feature gone, sorry guys, it was nice as a geek but no advantage is noticed if you use it. :)

    About RT-N76 .. it's delayed as I saw in Asus site and replaced by RT-N66 to be launched in CeBIT 2011.. will see the chipset used but as you know RT-N56 is using Ralink... not compatible with Tomato today..

    Wow no more cpu oc? Toastman swears by it and has said it gives a 25% increase with performance....... Not speaking for him. Just remember him saying oc is a good thing with the WRT54GL.

    2- Keep air free ventilation on WRT54GL, In my test after 10 minutes downloading 50mb dropped to 30mb without any reason, after opening router case and check for causes I saw BCM5352 (switch manager) at 55ºC. Applying FreeZero 50mb BW was restablished.

    Did that issue pop up when the cpu was overclocked? Or is that at the stock setting of 200MHz?

    On stock setting.. yes, pity.

    And comment about Tostman, my respect but at least performance is not evident in BW ... I don't know if he found some boost in other features...

    Add me to the list of people asking you to reconsider. While it may not have a linear effect on bandwidth, increasing the processing speed absolutely has to have some effect on the capabilities of the router, perhaps in IPTABLES traversal, connection setup, etc.

    Think about it for a second: if processing speed wasn't an issue, why are the 2.6 kernel versions such dogs on a WRT54GL, but acceptable on the higher processing capability hardware?

    In my experience, it really does make a difference, particularly with OpenVPN. Your mileage may vary, but none of my GLs and TMs are stock-clocked, and all are just fine on air.

    Vic...

    I also ask that you reconsider and keep the overclocking capability.

    I can see a difference with the router overclocked when I'm tunneling through it using Putty and an SSH session, or when the router is running OpenVPN as either a client and/or a server.

    So, while switching-related bandwidth may not be affected by overclocking, the processes running on the router do receive a benefit from the extra cycles-per-second provided by overclocking.

    1. Dropped to standard GL 1.1 @ 200MHz
    2. Slapped great big heatsink with goop off an old PIII Northbridge board. Fortunately the height of the Linksys GL case kept it in place.
    3. Tried Free Download Manager getting a Ubuntu Server ISO (from a local, well known high speed mirror) and couldn't get more than 4.5 MegaByte/sec. That's basically just under 50 Megabit/sec

    So how do I get 80MegaBit/sec?

    My Vista box was worse of course, but primary testing was with XP.

    Overclock

    Can`t you always overclock manually with a script or telnet commands even if overclock isn't in the GUI?, i don't think Victek disabled overclock, he just doesn't support it in the GUI. Am i right?
     
  26. ab2000

    ab2000 LI Guru Member

    Doesn't appear that 80Mbps is going to happen (or even +55Mbps for that matter), unless VicTek has something extra to add.

    Unfortunately it seems I'll have to look for alternatives.

    Many factors are involved in top speed download; line distance from central provider, router setup, netcard setup and os halfopen, tcp optimizing. My almost toptuned setup gets 17,5 Mbps out of 20 Mbps line. So router alone doesn't ever make it happen.
     
  28. ab2000

    ab2000 LI Guru Member

    Isolated testing outside of the router generates 85+Mbps from provider so I've covered those bases in point.

    When I was on 20Mbps, I generally got 18-19Mbps across an 8 year period. Of course there were more than 1 or 2 tests per year to clarify, several to say the least.

    We talk about router bandwidth, line condition are not considered ...test is made by packet from WAN to LAN without using ISP connection, just a packet generator.

    oh, that's an important fact! beforehand i thought you could get the stated bandwidth (50-80MBit) on the internet-line.

    referring to this message (http://www.linksysinfo.org/forums/showpost.php?p=373838&postcount=285) and due to advice from Victek i used version 1.28.121006 ...

    but unfortunately this fw didn't solve this specific problem. i have two wrt54-routers (WRT54G - v2.0 / WRT54GL - v1.1). to enable a internet connection i need to establish a PPTP-tunnel to the ISPs modem.

    the maximum bandwidth with the WRT54G is 5,4MBit
    the maximum bandwidth with the WRT54GL is 6 MBit

    the line itself is at 8MBit (which i get by using a linux-router (P3/933 MHz)). command "top" on the WRT54GL show's me:

    Code:
    Mem: 11156K used, 3372K free, 0K shrd, 1324K buff, 4452K cached
    CPU:  24% usr  71% sys   0% nic   3% idle   0% io   0% irq   0% sirq
    Load average: 1.48 1.45 1.33 3/26 2158
      PID  PPID USER     STAT   VSZ %MEM %CPU COMMAND
       69    68 root     R      688   5%  93% pptp
      478   465 root     R     1952  13%   1% top
      459    77 root     S     1600  11%   0% dropbear -p 22
      465   459 root     S     1972  14%   0% -sh
       68    65 root     S     1960  13%   0% sh -c pptp 10.0.0.138 --nolaunchpppd
       97     1 root     S     1960  13%   0% crond -l 9
    are the both routers to weak for en- and decapsulating the packets? or is there a way to tweak PPTP?

    but nevertheless THANKS for this great firmware!

    Um, wow!

    I never would have guessed that a P3/933 MHz was under-powered for an 8Mbps PPTP connection.
     
  32. ciaccom

    ciaccom Networkin' Nut Member

    just to get me right - the P3/933MHz "linux-router" managed the 8MBit pptp-traffic (incl. en-/decapsulating) easily. :tongue:

    but i would prefer to save some energy costs with replacing the linuxbox by my linksys-devices. they seem to be "under-powered" ..

    hello,

    is that the case or am i missing some options/parameters configured in the right way?

    thanks, ciaccom
     
  34. RonWessels

    RonWessels Network Guru Member

    I was looking at the 93% CPU usage by pptp and the >1 load average value when I made the "under-powered" comment. Just how much processing does pptp need to do anyway?
     
  35. ciaccom

    ciaccom Networkin' Nut Member

    @Ron

    ah, ok - just misunderstood you ..

    i don't know - that should be my question. i never heard, that the linksys-devices (i mentioned above - WRT54G/gl) are to slow to handle dsl/pptp-lines. 8MBit is not that fast - there are many faster alternatives out today.

    but anyway, there was no confirmation to the possibilty of "under-powered" devices from the experts.
