    I'm on cable broadband with a 10meg connection , with a wrt54gs running the latest tomato firmware , which was great until i noticed this ..
    when downloading through the router , i can only get a maxi download speed of around 5 meg , (on main hardwired pc, and no other pc's connected ) but if i use a direct connection (modem straight to pc , no router) i can get the full download speed ...

    I have no QOS setup ...

    What slowing the router down ????
    I never had this problem with other firmwares , so i can't work this out ...

    actually, tests have shown tomato is the fastest of all the firmwares out there. Perhaps its simply a issue with the sites you're accessing?

    Well , i use newsgroups , and in the mornings I can max out my 10 meg connection , and with Thibor 15c i did , but with the latest Tomato , i don't .
    This morning I tested this ... is there a setting my missing ??
    should i have something set that isn't set ???
    I've only got the 1 pc hardwired to the router , which has a static ip .

    You might want to test with this website to verify the problem and gather some more clues. It will test your upload speed as well. When you say you have no QOS setup do you mean that the QOS box is unchecked ?

    Yes m8 , it's unchecked

    MTU under basic - network is the only value to mess with as long as QOS is disabled. I get about 150 K more out of my 5 Meg cable connection when I set MTU to 1460 instead of 1500, but it sounds like your problem is more chronic than MTU manipulation would remedy. The only thing I could suggest is flash back another firmware to be certain that it is a Tomato issue, and not a new hardware issue that has cropped up. My experience confirms what Azeari says, Tomato is faster than any other firmware. I'm sure you have cleared NVRAM from the menu ? I've seen reports of this clearing up lots of quirks in other areas.

    Well I took your advice , and flashed back to Thibor 15c , and thats now the same , so this must be hardware now ..

    Can anything be done ??? or is it time to get a new router ???

    Do a loop ping to the modem IP which should be your public IP and wiggle and mess with the cat5 patch cable that connects the router to the modem. If ping time is consistently <1 ms, then it may be time for a new router. Buffalo whr-g54s is $41 delivered from NewEgg right now, and is a very high quality radio.

    Edit - U.K. ? Well, so much for the NewEgg advice. Sorry, I'm sure you know where to find hardware.

    Darn... I dropped in too late in this thread!
    I had something similar with my WRT54GL, traded it in and the new one had the same. It's something with the network-card in one of my PCs that is causing this.
    A complete power-outage in my home and thus of all connected systems made it work again at the expected speed.

    Have you tried reproducing the problem? like, testing with and without the router on the same day to double-check its not a random problem.

    also, i doubt the wrt hardware is at fault. I've managed to max out my 10mbs dsl connection without loading my wrt54gl much.

    One way you could check this is by going to the status page under overview in your router web-interface. The cpu load should be below 1.00/1.00/1.00. In fact, none of the numbers should read 1.00(which signifies max load)

    Another thing you could check is the pptp contrack, under advanced->Conntrack/Netfilter. click on the count current link to view the number of active connections. If the number's too close to your maximum connections, you might want to increase it. 4096 is a good and tested number.
