xbox wireless-g adapter (mn-740) loses network signal at r..

Archived from groups: microsoft.public.broadbandnet.hardware (More info?)

Have you tried as a test disabling MAC filtering & WEP?

It is possible that one or more of the devices behind the MN-740 are
attacking the router. I know of several viruses that do that.

So my suggestion at this point are to do the following on all computers
in your network.

Go to http://housecall.antivirus.com & do an online virus scan for free.
(I've seen several viruses cause the symptoms that you are seeing.)

Download, Install, Update, & then scan for spyware with both ad-aware &
"Spybot Search & Destroy".

I was running a virus scan, had run ad-aware and spybot,
and tried turning off MAC filtering (WEP was already off).
No luck. Identical behavior with a replacement unit.

I bought a Linksys product, and it's working fine. I'm
sure Microsoft's products are excellent (and are cheaper),
but the MN-740 doesn't seem to work with the SMC 7004VWBR.
