Default Very slow desktop, faster laptop

Recently replaced the old DSL modem with an Actiontec PK5000. Main system is wired and works fine, running Windows 7.

Machine2 is a desktop that had an old Belkin F5D6001 that only supported WEP. It is sitting in the same room as the modem, approximately 6 - 8 feet away - connection strength says it's excellent.

SO, I connected up and my download speed is only about 240KB. File transfer speed from main system to Machine2 is 880KB - this is on an 802.11G connection it SAYS is running 54MB/s. BTW: downloading the same file on the main system runs approximately 7MB/s, which is essentially full-speed on this line.

Replaced old card with Trendnet TEW-421PC. ALSO using WEP, I got D/L speed around 280KB/s and file transfer from the main system stayed around 880KB.

Used NETstumbler to check neighborhood channels and switched to one that isn't used by any other local networks. This SLIGHTLY improved file transfer speed to approximately 1.2MB/s.

I set the wireless on the modem to ONLY connect at 802.11G and wasn't able to connect using either the old or new cards.

Just to check I connected the 5-year-old laptop that supports both WEP and WPA and ran the same tests. File transfer speed was just over 2.53MB/s, mapping was much faster, and generally it acted fine.

The laptop connects fine using either WEP or WPA/WPA-2 and appears to have about half the throughput I'd expect from an 802.11g connection - which I presume is about all I'm going to get with overhead and such. True? False?

Machine2, the wireless desktop is running XP Pro, and the Trendnet card, which SAYS it supports WPA/WPA2 won't successfully connect using either. I have to stay at WEP to get a "reliable" connection. SO, what do I do to get this system to connect RELIABLY, quickly, and have decent throughput, mapping speed, and so on?



I presume all this indicates both cards are connecting at 802.11b speed and doing about as good as they're going to do on B.
