Wireless Networking Question

[AUII_Forte]

Hey Guys,

I am having a problem with our wireless network. Hopefully someone will be able to help me out!

Here's what we have:

Compaq Desktop AMD Athlon 1.83Ghz Belkin 802.11g Wireless card and 10/100 LAN Card Win XP

Acer Desktop Intel Celeron 1.2Ghz 10/100 Lan Card Win XP

Compaq Laptop Intel Celeron M 1.5Ghz Inbuilt 802.11g wireless card Win XP

What's Happening:

We are running a wired LAN between the two desktops and a wireless LAN between the two Compaq PC's and a bridge between the networks as well as a shared ADSL connection on the Compaq desktop.

When the wireless network is connected everything works fine, but the network randomly drops out. Sometimes it's possible to reconnect by clicking "repair" in network properties on the laptop, but 90% of the time I have to disable the connection on the desktop pc and then re-enable it to get the network to come back online. When ever the laptop is started up I have to go through this procedure, it won't just connect automatically and stay connected. I'm pretty sure it's a settings problem on the desktop pc, but I have been through every setting possible and nothing appears to be incorrect. The computers are no more than 10m apart and the properties are saying that the signal strength is excellent, so it's not a signal problem. It's got me tearing my hair out, I just can't figure it out! Any ideas????
