drop

Hi,

I have a wireless setup in my house, which is a linksys wrt54g which is
providing a wireless signal from my adsl connection . Picking this signal up
is my pc using a belkin f5d7000 pci card. I also have a dell demension 2400
laptop which is connecting wirelessly to the linksys.

Both connect and I can access the internet, which is the main use of the
laptop, but randomly the pc will drop its connection and when I go into view
wireless networks, where there is usually 2 networks , there are none.
Refreshing doesnt sort this. The only thing that does is a reboot of the pc.
As a test I have powered up the laptop when the PC has gone down and it can
locate the signals perfectly.

Has anyone any ideas on this ?

Thanks

Jon
