i have a siemens 242 2.4Ghz cordless phone that i just got.

at home i have a SMC 7004AWBR wireless router on 1st floor and have a computer with a SMC PCI wireless card in the basement.

For some reason as soon as i start to use my cordless phone my signal on the computer goes to zero.

im using ADSL and the cordless phone is in the basement as well

HELP HELP HELP!!
 
You can get a nice 900MHz phone for less than $10. The audio quality is as good as 2.4GHz.
 
These guys are both assuming that you realize both wireless networks for computers and 2.4ghz phones use portions of the same spectrum to transmit and receive. So you've got 2 options: change the channel your router is using, or buy a different phone.
 
Also keep in mind that with the unlicensed 2.4GHz frequency range there are only three channels that don't overlap each other -- channels 1, 6 and 11. If your router is on channel 6, change it to channel 1 or 11 and your performance should improve. Please note, however, that if you have a channel button on your phone or if your phone is auto-channel seeking, there is a chance that it could jump into the frequency range that you're using for WiFi (your phone could have 40+ channels, while your wifi has only 11 -- big potential for overlap).

We run into this issue all the time when deploying our wireless network -- if we use channel 11 for our actual internet link and the customer wants a wireless link, they *have* to use channel 1 or 6 or there will be (mild or heavy) interference with the backhaul.

it was at channel 6...so i switched it to channel 11...and VOILA

ITS WORKING perfectly...no interruption whatsoever when i use the phone..

thanx alot guys
 
When dealing with transmission, a specific channel does not mean one frequency ON and nothing else.

Channel means that there is a center Frequency that transmits Max. and from both side of this frequency the transmission declines, as you get further away from the defined center frequency (it is like an inverted U graph, and it is called the bandwidth of the transmission).

The most common example is the mixing and interference of Radio reception in an area (like NYC) where there is many stations.

The 2.4GHz band is very loaded with appliances that use it. While switching setting to channels that are very far apart like 6 to 11 get better results, do not kid yourself the best is simply not to use 2.4GHz phone.
