    I have som trouble getting max speed through my wireless network. I have a 3,5 MBits ADSL line and when I connect directly to the modem, I get full speed. When I use my WRT54G router and connect with cable to one of the ports, I get full speed. So there is obviously nothing wrong with my internet connection.

    But through the wireless network I cannot get a higher download speed than aboutn1,3 Mbits (have used several speed-tests, and I get this speed every time). Is there any settings in the router that I must change? I´ve tried changing channels, but it didn´t help.

    Should I download i new firmware? I´m using firmware ver. 2.02.7 now.

    Did you test speed from a wireless client to a wired PC. I use iPerf for that. You have two variables that affect download speed for wireless clients; routing performance and wireless. It is unlikely that routing for wireless is different from wired and you do not have problems with wired. If you isolate wireless performance from a client to a router troubleshooting would be easier.

    Check noise level and if there are other wireless station around (with Netstumbler).

    You firmware version if very, very old. It does not hurt to update but it would not solve your wireless performance problem. I personally like HyperWRT (for stability) but stock is OK too.

    You did not mention at what speed your client PC connects. A driver adjusts speed based on signal quality. A utility for a card usually shows it as well as signal and noise levels.
