Your MW is emitting enough 2.4GHz radiation to effectively jam other signals in the house, and you ditched the safe piece of gear? The MW should be FCC certified not to emit RF at all, actually. If the MW interferes with the wireless, the MW should be replaced.

I agree with djmcmath, try changing your wireless channel from the default. There are 11 channels available for B and G networks, 1,6, or 11 have worked best for me in the past. If you have secured your wireless (no broadcast, wep, etc) then I think you will need to configure your wireless cards for the same channel.

How close is your cordless phone to your router? Try moving one of them if they are too close.

Also if you have a fax line that should proabably have a filter as well.

masraum - The only problem with 802.11a is that is has a shorter range signal and can be easily obstructed. Of course if you live in an apartment or small home this may not be an issue.

Or just wait until 2008 when 802.11n is approved (270 Mbit/s) this may not fix your problem but your LAN will be blazing :)

Let us know how it goes.

Re: Wireless Router "lost" when using telephone
 

I have the same problem with Belkin(?) router I have had for a couple of years. The issue just started recently oddly enough. I use the speakerphone function when I need the phone. Keeps the calls shorter :)

I really need to look into the issue.

Well, I tried an old school corded phone, and that worked, no problem. Plugged the cordless phone back in, scanned for another channel, placed a call...problem solved! Thanks again for all the help.

Glad your problem is fixed, this sort of thing drives me nuts. I had exactly the same problem a while back, broadband would drop out when you used the phone, then started dropping out for no reason. Dunno how many times I rang the phone company and eventually they agreed to come out to take a look. Something made me take the cover off the wall socket before they came out just to check those wires were OK, and turned out a critter had manged to sneak up into the tiny little junction box and barbeque itself across the contacts. Removed the cremated remains, replaced the box and was all OK again :rolleyes:
