Slow speeds with Linksys WRT54G Version 5.0

    I've been using the WRT54G for a while now and haven't messed around with the settings much and got good speeds. But now the router seems to be rather slow when I'm using the wireless connection to it. What are settings that can greatly affect speed and reliability. I'm not sure which settings to play around with.

    If the factory setings are in place, no security, you should be getting max speed. The V5 WRT54G is the first in the series to use Vx Works and is going through many firmware changes in an attempt to make the router reliable. As of yet, in my opinion, its not even close :thumbdown: . My only suggestion is either return the router for something different or keep up with the new firmware releases in hopes of a stable reliable release. Good Luck

    lol i would not recommend NO security on a wireless router, you may as well leave your front door open as well then.

    There could be a number of reasons to speed being slow.

    packet loss, interference, other wireless clients.

    try some of these:

    make sure you have the latest version of firmware.

    If you have just one or two clients enabling frameburst in the wireless advanced page.

    Try using channel 1, 6 or 11 first of all, none of these 3 channels have cross coverage unlike the rest of the channels as they all overlap into other channel ranges and this will cause interferance. to any tranmitted signal.

    If your wireless devices are all 54G (802.11g) then if possible set your routers wireless mode to "G" only. if not set Wireless to B only (unless you have B and G devices) though B mode usually gives better signal than G, but is slower.

    Adjusting the "RTS Threshold" can help alleviate Packet loss. If one of the Wireless computers can obtain an IP address but can not ping, then set the "RTS Threshold" to 2304

    Adjusting the "Beacon Interval" can help association problems. If there is a wireless adapter that is able to see the access point, but is unable to get locked, try adjusting the "Beacon Interval" to 50

    Adjusting the "Fragmentation Threshold" can help association problems. If there is a wireless adapter that is able to see the access point, but is unable to get locked, try adjusting the "Fragmentation Threshold" to 2304

    Make sure CTS is disabled.

    I checked all those settings and followed everything except the RTS, Beacon and Fragmentation because I'm not having signal reception problems because my room is just next to the router and I get excellent signal. I tried resetting and reconfiguring the router and set a new password. I'm using WPA with TKIP encryption, I tried connecting two laptops and the speed was great and then I added 3 LAN cable clients to the back of the router plugged in and then things started to dramatically slow down. It was fine before with 5 people sharing the line, but now it's noticeably slower than before. I don't understand what happened. Would the high encryption level slow the speeds if more than 2 people connected?

    What firmware are you using?

    Speed was one of the issues fixed with the newer firmware releases for the WRT45G Version 5 (1.006 or 1.007 beta).

    Although one can see from other postings here and at the Linksys user forum at, Version 5 firmware is still very much a work in progress. Hopefully, Linksys will release a bug fee firmware.

    I have read that using WPA+TKIP for security is the slowest of all your choices. About 17% slower than WPA+AES, which is your best choice.

    WEP is 2nd at about 10% slower than WPA+AES.

    Since the router runs WPA+AES security from hardware, it has minimal to no effect on speed at all.

    What I haven't been able to find out is if WPA2+AES is also run from hardware. If anyone reading this knows, please fill me in.

    Can't say if this will solve your problem, but it should help your wireless speed in any case.

    Good luck.

    Trying to use WPA+AES right now, I'll see if it speeds up. I'm using the current firmware 1.006 right now. Any more ideas would be appreciated, thanks! :cheer:

    For some weird reason it just decided to get faster after my friends plugged in a D-Link ethernet hub based router for a while and when I switched back to the WRT54G it's so smooth now. Weird.

    Back to 56k style speeds, anyone have any thoughts about the beta 1.007 drivers? I'm just fed up with these speeds...

    I never had speed issues before, and I don't have such problems with the beta firmware.
    In fact, it didn't add any problem to my router. Also, corrected the UPnP flaw. So you can give it a try, although it may not resolve this particular issue. AFAIK, is basically a UPnP fix. You can give it a shot, remembering that this is a beta, so, if with my configuration functioned, it may work not so smoothly for you... :???:
