Well, i just spent a ton of money for a D-link DI-524 802.11g router and 2 D-link wireless cards.

My parents finally found a cordless phone that they like, a multi handset Radioshack 2.4ghz phone.

Well, i set up my network, and everything was going fine until about 3 days ago when my sister answered the ringing phone. All of my network connections dropped.

Now, whenever someone answers the phone i have problems. Ive tried a few different channels but i cant seem to find one that works better then the rest. I cant replace the phone, i cant switch to 802.11a, so what can i do?

I haven't heard of that problem before. I set up wireless networks at my house, both my sister's houses, and my mother's house. We all use 2.4 Ghz phones. We've never had a problem.

Well, i looked this up on the net, apparently this is quite common. Maybe its just a cheap phone?

I HATE RADIOSHACK!

Is there some sort of program out there that monitors all of the channels and detects interference so i can figure out what the best channel to use is?

In studying for Network+ all my books say that if you're going to set up a wireless network and use cordless phones around them, your cordless phones should operate at 900Mhz, or you'll end up with serious interference.

In what I found on the internet, 802.11g works at 5.4 Ghz and shouldn't interfere with 2.4 Ghz phones. Unless the cards you bought are 802.11b.

If so, you'll either need to buy a different phone or wireless cards on 802.11g.

This came from another forum:

Get a "802.11 friendly" 2.4GHz phone. These are usually labeled "DSS" or "Digital Spread Spectrum".

802.11b and 802.11g both work on 2.4 Ghz. 802.11a works on 5 Ghz UNII bands. You can get a lot of interference from 2.4 gig phones when using 802.11b/g, especially the latest generation of phones. Switch to 900Mhz or 5 Ghz phones if you want to use 802.11b/g reliably.

Well, i finally figured it out!

Channel 6? Bad
Channel 1? Horible
Channel 4? Terrible
Channel 11? HORRIBLY BAD AND TERRIBLE!
Channel 2? Perfect! No interference on either the network or the phone!

I ran into the same problem with a Linksys WRT54G. Would kick off internet connection when the telephone rang. Just changed the channel to Channel 2 and everything worked OK after rebooting the router. You might also try to set the frequency channel on the telephone. Sometimes these telephones rotate frequencies.

All of our RC cars interfere with our cordless phones, and it doesn't matter what channel we're on. And the cars are all at 27 and 47 mhz.
