Is it true that 802.11b uses the same 2.4Ghz frequency that a lot of cordless phones use? My friend said that every time a call comes in it knocks out the network connection. If that is the case, why isn't that advertised more, not by the companies of course, but by people in general in the How-To forums and FAQ. This is like the first tim I've ever heard of that, and 802.11b has been around forever.

There is a lot of info out there that Fast Food is Not Healthy, Smoking and Drinking is Not Healthy, and more.

Does it Help? Nah!

And there is always Google.

http://www.google.com/search?s...+and+802%2E11+Wireless

Have a problem get a 900MHz. (it only $10). Or Upgrade to 5.8GHz. and ditch the 2.4GHZ it just a piece of plastic.

Have a Nice Holiday.

Yes, they do both use the same frequency band and can have a lot of problems because of that. But why don't companies tell you? Because they can make money off of you regardless of if you have done enough research.

802.11g ("54"Mbps) uses the same range as well.

You can try moving channels. Channel 1, 6, and 11 tend to not overlap (TEND : Not absolute).

Good Luck

I see you did a search on google for "2.4GHz phone and 802.11 Wireless," but that is as obvious a search as doing "802.11 Wireless and Salami" if you didn't know there was a relationship. I've never done a search on google for "Pacemaker and 802.11g" either (well until now).

Like they say, you don't know what you don't know.

It's a VERY common topic on the newtworking boards on pretty much every major, and minor, Tech BBS in the world. Hard to believe you've never heard of it before. Must not be a Forum regular at too many places. I

There are 802.11 g and b friendly phones out there too. I had the same problem until I replaced my phone with one clearly labeled network friendly.

Let me add another note though. I just connected my wireless last night and I have a 2.4Ghz phone, and not a single problem. In fact I didn't even remember that issue until the end of the night. I know there are channel selectors on the router's config page, but I used whatever default. So there must be more to this issue, again that isn't widely discussed. Either it is blown out of proportion or some phones are more troublesome than others.

And I haven't been a regular. I got my overdose of Hot Deals and have been more active in other boards like motorcycle, cars, and finance stuff. Everything is seasonal. Thanks anyway.

FYI microwave ovens can cause the same or more problems. They tend to bleed RF all over the 2.4 Ghz range. Older and cheap ones seem to be worse than newer better ones. We have 2.4Ghz phones in the office and if you're within 15 feet of the microwave it will wash you out in a minute, dito for the wireless laptop connection. As the others said wireless phones and wifi usually get along pretty well if you change the channel on the WAP.
