I added a Netgear WG602 wireless access point to my home network today.
Everything works fine as long as I'm the only one connecting to this access
point. When a second laptop is started though after a couple of seconds the
first laptop is not online any more. Actually the wireless connection to the
access point still exists. The laptop keeps sending data but does not
receive anything (or nearly anything). When I try to ping the gateway all
packets are lost.

When I repair the connection (the first laptop has Windows XP Pro. SP2
installed) everything works again. However you see the same problems after a
few seconds on the other laptop (which has Windows XP Home SP2 installed).
Again Windows says everything's fine (there is even a strong signal).
However no data is received anymore.

I would appreciate any hints how to get two laptops to work with an access
point at the same time. I don't know if it's important but the network is
currently WPA/TPK encrypted and uses channel 10. There are a few other
wireless networks around me.

Thanks in advance,
Boris
