Phone knocks off WiFi

[Brett_Tabke]

Why would a cordless phone knock out a WiFi connection? (900mhz phone). Using internet, phone rings, wifi lost. hmmm. That just don't seem right.

I was buying a new microwave oven and a cordless phone, so I read the reviews from consumer reports. They said don't use a 2.4 GHZ phone if you are using a microwave near it.

When I got the phone under troubleshooting one of the causes for poor reception is as follows:

You're too close to appliances such as microwaves, stoves, computers.

wierd....

Welcome to the wireless world, I guess... My cell phone wipes out my FM radio and makes my monitor squiggly if it's too close. Just got a little TV for the kitchen and the 900 Mhz phone causes a major whine on the TV audio when in use.

I guess with all these signals floating around there's bound to be some interaction.

My weirdest interference is from powerful CBs on trucks. I've gotten CB calls through my FM radio at work when the radio was OFF. (Scares the heck out of you when your radio starts yelling at you unexpectely!) I suspect those truckers are doing a bit of non-FCC signal boosting. ;)

I've heard of other people having trouble with their WiFi and 900Mhz phones, but usually the other way around; I've heard them say their WiFi clobbers their phone.

I think this depends on what brand of hardware you have. I've got a Siemens 900Mhz spread spectrum phone right next to my Linksys 802.11b Wireless AP/Router with no problems whatsoever.

Up here, the university did some kind of microwave signal experiments that knocked out the wireless internet connections of half the city. (It's a small city, but still... hehe) Solar flares can mess up wireless internet connections something awful too.

Heck, it's not just competing signals sometimes. There's a specific spot in my living room where someone standing will almost wipe out the tv signal.

Brett, any way you could rearrange the house so the phone wasn't coming into the wifi connection's "line of sight" to the computer, maybe?

It's could be a number of things. ALL cellular phones cause a degree of out-of-band interference.

Possible causes include;

- Phone 'slightly' faulty, producing extra out-of-band radiation.
- wifi card not sheilded correctly, signal affecting internal workings. (more likely)

.....or my personal favorite.....

"rusty bolt effect", the mobiles signal is mixing (where rust occurs) with other signals - which when combined, hit the wifi frequency.....How rusty is your office?
