Questions about overclock and speeds

Discussion in 'Tomato Firmware' started by gabriel, Dec 6, 2006.

    Hi all,

    I use Tomato for two monts (switched from DD-WRT) and it is what I needed! Thank you for the good firmware!

    I have fast internet connection via PPPoE limited by ISP to 40Mbps downstream and 40Mbps upstream, and i have WRT54G V2.2 + Tomato (version 1.00.xxx since yesterday :) ) The Tomato is fastest fiwrmware I've ever found (I did a lot of tests with other firmwares) but it still can't handle the throughtout with this hardware. The best on WAN is approximately 24Mbps. Currently I have 1.0/1.0/1.0 CPU load on router while downloading big files. Thats way I think about overclocking it....or buying another router.
    Unfortunately the overclock of tomato seems to be imposible because it resets clkfreq to 216 after reboot. I want to overclock the router to 252 MHz, with active cooling ofcourse, and I hope this will give me a better troughput. Any ideas how to do that?

    Second thing I noticed is strange behavor of upload / download speed ratio. I tested with three computers. My test scenario is:
    (1). PC connected to WAN port of the WRT via cross cable.
    (2). PC wired to LAN port
    (3). PC as wireles client
    WRT is in gateway mode, obtaining address form WAN via DHCP, wireless is WEP protected. All settings except WEP are "factory defaults"

    On (1) i run a FTP server. I mesured download and upload speeds from (2) and from (3). So, the case is that the download (1) -> (2) is twice faster than upload (2) -> (1) and download (1) -> (3) is twice slower than upload (3) -> (1). Can somebody explain me way this happens?

    Sorry for the long post and thank you for any suggestions!




    P.S. Sorry for my spelling! English is not my native language and even the alphabet is not my native. :)

    as to the raw throughput conecrns for your ISP connection, from what I have read there is a physical limitation of the brocadcom chip that would be your bottleneck. This only occurs on the WAN port, which is obviously not 100mbit b/c of this restriction. Where the exact sped cap of the WAN port is, and whether or not overclocking the chip is going to yield a speed increase on the WAN side, I haven't the fogiest idea. There may be some way that if u know iptables and such, you could specify on of the switch ports as the WAN and do PPoE with it. However, you still may get slammed by the maxx speed of the main chip. So, you may have to move up to a pro level router to get the max throughput speed out of ur connection.

    (on a side note....WOW to the 40mbit/40mbit connection. i wish I have even 1mbit up.... :( )

    Read this very informative page about overclocking.

    http://www.bitsum.com/openwiking/owbase/ow.asp?WRT54G

    I can personally overclock my WRT54GL v1.1 to 240MHz without any additional mods or cooling.

    I can do 250MHz, but my wireless radio will ocassionally drop out when the weather gets warm (which says it's a cooling problem).

    and welcome to LinksysInfo.org!

    A 40Mbps PPPoE connection is bloody fast! Which ISP is it?

    How did you measure your WAN speed? Was it also over a wireless network? A standard 802.11g wireless network while connecting at 54Mbps only has a maximum throughput of about 25Mbps at best and anything sent across a network that involves wireless network tends to run a bit slower than its LAN equivalent due to the larger overhead and can degrade as signal quality degrades over distance.

    Just to caution anyone who is considering overlock I bricked my WRT54G v2 last night.

    (If anyone has any suggestions on how to revive it, I have been looking at the debricking procedures, as well as the JTAG stuff)

    I have performed the failsafe and ftp, but after restaring the router I still have the powerlight blinking... I can ping, but the config page doesn't come up... do I have to use OpenWRT or can I use Tomato 1.0 when I use "tftp"?


    I am going to try again tonight and if that fails I will look closer at the JTAG method

    Davka LI Guru Member

    How much did you overclock when it bricked?
     
  7. digitalgeek

    digitalgeek Network Guru Member

    From 200 to 225...

    I entered the following:

    nvram set clkfreq=225
    nvram commit
    reboot


    (Keep in mind this is a WRT54G v2 which uses an ADM chip not a Broadcomm)

    The ISP is telecomunication company I'm working for....40/40 is not commercial product. Sorry.

    I did the tests again today. I used two PCs, and one WRT54G :)
    One of the PCs was a FTP server and second one - FTP client. The speeds are measured as transfered bytes / time. Yes, I know that this will not give the exact troughtput, but is close to. The arrows bellow shows the transfer direction.I also flashed the router with DD-WRT and overclocked it to see results...so, the values are:

    PC (FTP Server) -> Crossed Cable -> PC (FTP Client) 88MBps
    PC (FTP Server) <- Crossed Cable <- PC (FTP Client) 70MBps



    WRT54G V2.2 with Tomato 1.00.xxx, factory defaults, 216MHz, 128 bit WEP encryption

    PC (FTP Server) -> (WAN) WRT54G (LAN) -> PC (FTP Client) 24MBps (28MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (LAN) <- PC (FTP Client) 30MBps (32MBps with two upload sessions!)
    PC (FTP Server) -> (WAN) WRT54G (WLAN) -> PC (FTP Client) 13MBps (17MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (WLAN) <- PC (FTP Client) 20MBps (23MBps with two upload sessions!)

    PC (FTP Server) -> (LAN) WRT54G (LAN) -> PC (FTP Client) 88MBps
    PC (FTP Server) <- (LAN) WRT54G (LAN) <- PC (FTP Client) 70MBps
    PC (FTP Server) -> (LAN) WRT54G (WLAN) -> PC (FTP Client) 15MBps (15MBps with two download sessions)
    PC (FTP Server) <- (LAN) WRT54G (WLAN) <- PC (FTP Client) 20MBps (20MBps with two upload sessions)



    WRT54G V2.2 with DD-WRT v23 SP2, factory defaults, 216MHz, 128 bit WEP encryption

    PC (FTP Server) -> (WAN) WRT54G (LAN) -> PC (FTP Client) 18MBps (20MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (LAN) <- PC (FTP Client) 21MBps (22MBps with two upload sessions!)
    PC (FTP Server) -> (WAN) WRT54G (WLAN) -> PC (FTP Client) 9MBps (12MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (WLAN) <- PC (FTP Client) 16MBps (16MBps with two upload sessions)

    PC (FTP Server) -> (LAN) WRT54G (LAN) -> PC (FTP Client) not tested
    PC (FTP Server) <- (LAN) WRT54G (LAN) <- PC (FTP Client) not tested
    PC (FTP Server) -> (LAN) WRT54G (WLAN) -> PC (FTP Client) 12MBps (12MBps with two download sessions)
    PC (FTP Server) <- (LAN) WRT54G (WLAN) <- PC (FTP Client) 16MBps (16MBps with two upload sessions)



    WRT54G V2.2 with DD-WRT v23 SP2, factory defaults, 252MHz, 128 bit WEP encryption

    PC (FTP Server) -> (WAN) WRT54G (LAN) -> PC (FTP Client) 21MBps (23MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (LAN) <- PC (FTP Client) 24MBps (25MBps with two upload sessions!)
    PC (FTP Server) -> (WAN) WRT54G (WLAN) -> PC (FTP Client) 10MBps (13MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (WLAN) <- PC (FTP Client) 17MBps (17MBps with two upload sessions)



    Yes, a lot of digits. But if you look at them carefully you can see a lot of things.
    First, maybe my previous test, with 3 PCs was somehow wrong. The upload/download are not differ twice! But looking from point of the client, the upload is faster than download! And having two simultaneous sessions increases the throughtput. Is it kind of reservation whitin WRT54G?
    The overclock improved the speeds, but not as expected! As you can see the difference in the performance of both firmwares is significant. Maybe overclock of Tomato will give beter results, than overclocking DD-WRT. Who knows...

    Interesting :D Are you going to do tests with Tomato at 252MHz?
     
  10. crawdaddy

    crawdaddy Network Guru Member

    I think I'm sadly going to have to give the advice of: if you want that throughput, spend the extra cash on a nice cisco router, and use the WRT as a WAP only. You're not going to get the max throughput out of a little 50-70 dollar box.....not on othe WAN port at least...
     
  11. arigosh

    arigosh Network Guru Member

    According to the WAN to LAN throughput table in Tomsnetworking 20-30 Mbps is what you would expect to see on an older WRT54G router: WRT54G Ver 1 clock at 20Mbps and WRT54GS Ver 1 clocks at 34Mbps, while the newer WRT54GL Ver 1.1 clocks at 54Mbps. My guess is that the most recent products such as WRT350N and WRV4400N Will have even better performance.

    Hmm. I just tried setting the clkfreq via nvram and it didn't stick.
    #nvram clkfreq=240
    #nvram commit
    #reboot

    #nvram get clkfreq
    216
    #
     
  13. rcordorica

    rcordorica Network Guru Member

    the command is:
    nvram set clkfreq=240

    you forgot the "set"

    luke-san LI Guru Member

    If you can ping it, try to tftp it when you boot the WRT54.
    A good and free TFTP tool = SolarWinds TFTP Server

    some pointers:

    -I think you know this, but use static IP

    -Use the mini-dd-wrt image. (>2MB)

    -If it transfers succesfully then you are ok, BUT, after the succesfull transfer wait untill it reboots -> my first time mistake at 3am

    -After that you can upgrade to Tomato

    Let us know what happens!
    Good luck

    Gabriel,
    Did you finaly managed to overclock your router, even after a reboot ?
     
  16. digitalgeek

    digitalgeek Network Guru Member

    no I did not overclock it... I was able to bring it back using failsafe... (short pin 16 to earth ground, and tftp (in windows). and I was able to use the Tomato code.bin file... all is good I will leave overclocing alone for know I network is to valuble at this time.

    For the kind of connection this thread was started for (sorry for hi-jacking you thread) you should look at a cisco (or equivalent) routing device. The wrt series as good as it is, is a toy and only ment for simple low bandwidth home and small business applications... 40m/40m wow... and I thought my isp was generous with 5meg/800k... ???

    good luck in your search for better hardware... overclocking can be dangerous, and I am going to dop some more research before I look at it again.
     
  17. gabriel

    gabriel Network Guru Member

    Yes, I found that link in Tomsnetworking yesterday. It seems there is another brand of routers capable to handle 40 Mbps. But they may lack the custom firmware capabilities, which is somehow disappointing.

    No, I didn't manage to overclock Tomato, but I tried only with version 0.9.
    Tomato resets to default 216 MHz after reboot. That's why I posted here - to ask how to overclock Tomato :).

    And a little bit outside of the topic: Does any body here have some experience with HomePlug devices? It might be the solution I'm looking for. I’m just wondering do they have some special requirements to the electrical network - special wires, shields, etc.?

    gabriel Network Guru Member

    Thank you Jon for the fast reaction!!

    Here are the results of the test I made overkloking tomato at 252 MHz


    WRT54G V2.2 with Tomato 1.00.xxx, factory defaults, 216MHz, 128 bit WEP encryption
    PC (FTP Server) -> (WAN) WRT54G (LAN) -> PC (FTP Client) 24MBps (28MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (LAN) <- PC (FTP Client) 30MBps (32MBps with two upload sessions!)
    PC (FTP Server) -> (WAN) WRT54G (WLAN) -> PC (FTP Client) 13MBps (17MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (WLAN) <- PC (FTP Client) 20MBps (23MBps with two upload sessions!)
    PC (FTP Server) -> (LAN) WRT54G (LAN) -> PC (FTP Client) 88MBps
    PC (FTP Server) <- (LAN) WRT54G (LAN) <- PC (FTP Client) 70MBps
    PC (FTP Server) -> (LAN) WRT54G (WLAN) -> PC (FTP Client) 15MBps (15MBps with two download sessions)
    PC (FTP Server) <- (LAN) WRT54G (WLAN) <- PC (FTP Client) 20MBps (20MBps with two upload sessions)

    WRT54G V2.2 with Tomato 1.01.xxx, factory defaults, 252MHz, 128 bit WEP encryption
    PC (FTP Server) -> (WAN) WRT54G (LAN) -> PC (FTP Client) 28MBps (33MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (LAN) <- PC (FTP Client) 35MBps (38MBps with two upload sessions!)
    PC (FTP Server) -> (WAN) WRT54G (WLAN) -> PC (FTP Client) 19MBps (23MBps with two download sessions!)
    PC (FTP Server) <- (WAN) WRT54G (WLAN) <- PC (FTP Client) 26MBps (29MBps with two upload sessions!)
    PC (FTP Server) -> (LAN) WRT54G (LAN) -> PC (FTP Client) 88MBps
    PC (FTP Server) <- (LAN) WRT54G (LAN) <- PC (FTP Client) 70MBps
    PC (FTP Server) -> (LAN) WRT54G (WLAN) -> PC (FTP Client) 24MBps (28MBps with two download sessions)
    PC (FTP Server) <- (LAN) WRT54G (WLAN) <- PC (FTP Client) 30MBps (30MBps with two upload sessions)

    As expected, the improvement is there...:)

    For those who going to overclock - for WRT54G v2.2 the proper commands are:

    nvram set debug_clkfix=0
    nvram set clkfreq=252,126
    nvram commit
    reboot

    It works on Tomato v 1.01.

    BTW: The chips didn't get hot (checked by finger) during the test. So, the cooling might not be necesseary at this frequence, but is good to have it.

    There are 2 general types. One type is 14 Mb spec, and the newer ones are 56 Mb (higher on some brands). I have the 14 Mb version. The type of A/C wires are not much of a factor. The signal is shortwave radio that uses the wires for an antenna, so the wiring type is not very important. My bandwidth drops pretty fast when I use them more than 50 feet apart, but I have the cheapest ones I could find just to play with them. You should get the newest and fastest design for best performance. The restriction to homeplug signals is that they will not travel beyond the power transformer on the urtility pole.

    Also keep in mind that PPPoE uses the cpu and can slow things down a bit.

    The incoming packets must be disassembled, the ppp packet is encapsulated inside the ethernet packet, and put back together in the correct order. So it will use some cpu overhead.

    Awhile back I did a test using a wired home made router from a spare pc and two eithernet cards running a single floppy disk Linux router/ firewall distro called Dachstein.

    The first system I tested was a 486DX-40 cpu and the download speed, as tested with http://dslreports.com, was around 530 kb/s on a 1.5 meg down/ 384k up DSL line.

    The second system I tested was a 400 mhz PII cpu and the download speed was around 1200 ~ 1300 kb/s

    Overlocking in WET bridge mode

    After I saw this post, I set my two WRT54GS v2.0 routers to 252 MHz, since that revision uses the same hardware as your WRT54G v2.2. One is in AP/gateway mode, the other connected to it in WET bridge mode. Tomato defaulted to running these at 216 MHz.

    However, with both running at 252 MHz, the WET bridge would disconnect within a minute or so. If reset, it would re-connect, and then drop again. The AP appears to have no issues with any other wireless clients (except the WET bridge) when running at 252 MHz.

    I then set the WET bridge to 240 MHz via:

    nvram set debug_clkfix=0
    nvram set clkfreq=240,120
    nvram commit
    reboot

    At 240 MHz, my Tomato WRT54GS v2.0 WET bridge is now completely stable and continuously connected to the 252 MHz Tomato WRT54GS v2.0 AP/gateway.

    What exactly does nvram set debug_clkfix=0 do and where do i find the "run" place to input commands into tomato?:D
     
  23. dvaskelis

    dvaskelis Network Guru Member

    The debug_clkfix=0 apparently allows overclocking, otherwise Tomato doesn't allow it.

    From the web-based GUI, under Administration: Admin Access, you can enable an SSH daemon (Dropbear) and/or a TELNET daemon to allow access to a BusyBox CLI.

    Sorry to up this thread, but my question is similar to this.

    For me, I overclocked my WRT54Gv2.0 to 252 and it seems to be a limit, as the next level of 264 seem to cause some problems with the wireless stability. So I reverted back to 252.

    For the next router WRT54Gv2.2, I kept to the limit of 252 and dared not go to 264 anymore.

    I would like to ask what is your experience in overclocking WRT54G, and the practical limit that u managed to reach?

    Hi, I find it safest to clock at about 240MHz with passive heatsinks. and store all preferred settings onto a modified cfe. I use a hex editor, to modify a backup copy of bootloader and add various nvram defaults, making the settings "stick" after a reboot/reset/factory defaults. I also make changes so as to easily recover from an overclock brick, without the use of a jtag cable.

    Currently, I don't really like to overclock as the net gain is quite small. I don't recommend using a small form factor pc or an old pc for that matter. An embedded device may be better or one of those newer wrt350n/600n routers if you've got very high speed connections. Granted, the stock firmware is a bit bland, hopefully eventually upgradeable to 3rd party firmware.

    As of today, my WRT54GL v1.1 is running at 240MHz. I've installed a heatsink on top of the BCM, by using Arctic Silver Ceramique and a lil' bit of silicone paste (to "glue" the heatsink's "ears" to the board - it's a NB heatsink).


    Benchmarks.

    Setup:

    a) WRT54GL v1.1 running Tomato v1.21 Official.
    b) Ahtlon64 @ 3800+, nVidia embedded nForce 400 Ultra LAN card, wired connection to the WRT;
    c) 50 mbps PPPoE WAN connection (RDS Fiberlink, Romania).

    Tests were carried out by downloading a 1GB file from the provider's FTP. Results represent the average speeds recorded over a 5 minute timeframe (software used for recording: DUMeter).

    Results:

    1) @200 MHz:

    - With QoS enabled: 3.1 MB/s;
    - With QoS disabled: 4.4 MB/s.

    2) @240MHz:

    - With QoS enabled: 4.6 MB/s;
    - With QoS disabled: 5.7 MB/s.


    Stability tests: soon to come (only just did the mod).

    Throughput will be a bit lower depending on the # of connections used, whether wireless is used or if others are also using wireless, and other lan-lan & lan-wan activity. Other "services" can gobble a bit more of cpu. I find the new bcm5354 at default 240MHz performs much better/more efficiently than the WRT54GL's bcm5352 at OC'ed 240MHz. You'll see sporadic performance during high cpu usage.

    Newer draft-n routers has 500+MHz cpu's to habdle the load of dual band draft-n and gigabit wired simultaneously. Dual band draft-n are now about $100 (not simultaneous dual-band). Your under-utilizing your connection when using a WRT54GL with your high speed connection.

    Is that sort of performance hit typical with QoS enabled? On a 4Mbps broadband connection would someone still see that much of a difference?
     
  29. bripab007

    bripab007 Network Guru Member

    When I do speedtests, I see no difference in download speeds between QOS enabled/disabled. I see a difference in upload speed merely because I've entered in a value that's ~90% of my max, to prevent dropped packets/excessive latency.
     
  30. TVTV

    TVTV LI Guru Member

    No. In your case, the WRT54's CPU will easily handle both your traffic and QoS.

    No other programs were using the connection, aside for the FTP client used for the test. Also, there were no wireless clients connected to the router at that time.
    I actually have no reason for buying a newer/faster router, because 4 MB/s are more than enough for my needs. Also, i don't need wireless N because all my wireless decives are B/G only. :)

    kardzzz Addicted to LI Member

    TVTV, I am watching your results with interest, i have a WRT54GL and was thinking about the OC route, but going for a moderate 216 or 232 rate. (I will be adding a heatsink)
    Please let me know if you see any downside.

    Is the following correct and does it need a manual reboot?

    nvram set clkfreq=232
    nvram commit

    thx

    kardzzz Addicted to LI Member

    OK guys, here are my finding on WRT54GL ver 1.1 running Tomato 1.21 Victek modded
    Speed. Installed Aluminium heatsink with Akasa thermal compound.
    216 - LAN OK WLAN SSID broadcast, no access to WLAN
    225 - LAN OK WLAN No SSID broadcast, no access to WLAN
    240 - LAN OK WLAN No SSID broadcast, no access to WLAN

    I put my transmit power to 30 for the whole test (usually power =75)

    I've put the router back to 200mhz and restored my settings. WLAN and LAN back to normal, but keeping a close eye on WLAN.

    Be very careful!!! I can afford to brick my router and buy another.

    **At 216mhz, Tomato was handing out the correct IP in range however it seems clients can not decipher the information hence can't connect

    Running WRT54GL 1.1 with a setting of clkfreq=250 without changing any hardware.

    Firmware: victek mod 121 which shows the 250 in GUI.

    The router runs perfect for about 3 weeks now.

    Elanzer Addicted to LI Member

    I've been running at 250mhz on my WRT54GL v1.1 for about 2 months now, have had over 30 days uptime with tomato 1.19 at 250mhz.

    Now, currently 20 days uptime on Victek's modded Tomato 1.21 (released Aug 28th).

    Transmit Power set to 70mw

    No hickups, router is just barely warm to the touch, no additional cooling of any sort added.
     
  35. kardzzz

    kardzzz Addicted to LI Member

    jnappert/elanzer, thanks for your feedback. I thought 250mhz was the magic number so gave that a try. No joy for me. I guess it's "horses for courses" with this one.

    In terms of performance at 250mhz v 200, is it noticeable? I'm thinking about purchasing a Buffalo WHR-G125 or maybe another WRT54GL for modding.
     
  36. jnappert

    jnappert LI Guru Member

    For "normal" surfing, it is not noticeable. Running p2p in combination with VOIP and things like the "adblock script" it is an advantage.

    For buying a new router i recommend an ASUS WL500gp (v1! not V2) which runs tomato nearly perfect. 264MHZ CPU (can be overclocked to 300MHZ without cooling) and 32MB RAM.

    I overclocked my wrt 54gl to 250mhz (stock 200Mhz) and i got a "speed" boost for my internet connection over pptp. I think the Router is too "slow" for connections over 8Mbit with adblock and "sometimes" qos. I got 850kb/sec with stock speed and with oc settings i got 900kb/sec with only the "modem" i got 920kb/sec.

    But i like the WRT mutch more then the "stock" modem/router.

    Anyway is there a "trick" to got my 920kb/sec with the WRT??
     
  38. bripab007

    bripab007 Network Guru Member

    I get far more than 920kilobits per second on my WRT, and I have QOS turned on. I suspect you meant 920kilobytes per second, though, and I've seen some P2P downloads get that high as well.

    920kiloBYTES=kb for me...sorry. (8mbit and then 920kbit is a bit VERY SLOW)

    and i don´t mean P2P!! I use a fast ftp or http connection.

    So you're saying you were getting 8megabytes/second transfer speeds before, and now you're getting less than 1megabyte/second?

    First off, where in god's name did you find an FTP or HTTP site that had transfer speeds of 8megabytes/second over the internet?

    Secondly, that's precisely why I mentioned P2P, as that's the only time I've seen internet transfer download speeds that high. Actually, I seem to recall getting in the 1megabyte/second download range when my Xbox360 pulls downloads/demos from Microsoft's servers, because I'm guessing they have a pretty fat internet pipe for their server farms.

    You understand me wrong...

    8mbit=8192kbit=1024kb(kilobyte)-> ca 1mb/sec (MAX INET CONNECTION) but with overhead and co i got 920kb out of my MODEM and only 900kb OUT of my WRT...

    don´t mix kilobyte and kilobit :D or megabyte und megabit!!!!! VERY IMPORTANT...

    50 mbps line over PPPoE, QoS on, WRT54GL @ 240 Mhz, DUMeter set to average.
    Stable as a rock for 5 days now. Wireless works flawlessly.

    Looks pretty choppy there. Can you run a large download and show us sustained speeds of 50 megabits?

    I have doubts that any hardware that runs Tomato can do anything more than 40 megabits with QOS OFF. I tested a 240mhz ASUS WL-520GU (BCM5354 chipset) and the most I got with QOS off was 37 megabits sustained. That was with 1.17. I haven't tested 1.21 w/speed mod. I will do a new test this weekend.

    I'm just wondering if the PPPoE is done on the modem or the Tomato router? Your speed WILL be much less if it's done on the router. "Jagged" graphs can be caused by cpu maxing out. Once you factor in high speed upload and/or many connections you'll see the speed dropping dramatically. Just wished Tomato would work on newer routers.... I always test by starting a dozen or so torrents of well seeded linux distributions and watch the graph go for an hour or so...

    Are you using the router as the PPTP client/server or your PC?

    the router config @wan is set to pptp so i think client!! (BASIC->WAN->PPTP)
    IP 10.0.0.140 (router)
    Sub Net 255.255.255.0
    Gateway: 10.0.0.138 (Speedtouch Modem)
    the router connect to the "thomson Speedtouch" Modem.

    My PC is only a "Client" of the Router.

    IF i use only my PC and the Modem with a PPTP Connection with the above settings i got 980~1000kb/sec.

    I have a WRT54GS v1.1. I want to overclock to 250mhz (now its set by default to 216Mhz).
    I read the thread from Toastman who overclocked his WRT54GL ...

    So I wanted to ask before I am going to overclock if someone has successfully overclocked a WRT54GS v1.1 to 250MHz .?!

    Thank you..

    The GS does *not* overclock as stably as the GL. Be careful!

    So I will beetter go with 240MHz instead of 250MHz ?! ...
