Drop in Connection

Hi,

I am using an ATMEL access point which is connected to my home network.
I roam around the house with my laptop using a Cisco Aironet card.

But...

It doesnt matter where i am in the house every hour or so the connection
will drop off completly and then 3 secs later will come back on. So one min
i will have 100% quality and strength and then 0%! and i wouldnt of moved or
anything.

I have turned off 802.11 verification but that didnt affect it.
I have turned WEP on and off and that didnt affect it.

anyone got any other ideas?

it is dam pain cause i use terminal services which bombs out straight away
soon as the connection is lost.

cheers
