wireless reconnection in T60 when my R32 is also connected

[Wiking]

hi,
I have a D-link DIR 615 router, Thinkpad T60, Thinkpad R32 and HTC desire.
All three connected to the router wireless. When T60 and HTC connected everything works fine but when I connect the R32, my T60 wireless adapter (intel 3945ABG) starts to drop connection and reconnect every 2 minutes.
I configured dynamic IP in the router and all 3. The router is secured with WPA. Also, configured different channel in the router but still, the T60 drops the connection when I connect the R32 to the network.
2 days ago I refreshed my R32 to factory state with hidden partition and since then, this happening. Before that, it didn't happened.
What can be the problem ?
Thanks you
Lior

Could be that the R32 only connects at wifi-B, whereas the others connect at wifi-G, disrupting the whole circuit down to -B.

The R32's wireless card is Atheros brand and for sure supports B & G. Normally it didn't come with it. I upgraded it about 2 years with this card.

Try a new driver for the "wireless card is Atheros brand"

But how this will help me if the T60 drops the conncetion ?

Well, obviously the R32 is causing the problem, NOT the T60!
So that's where you need to do the work.
