2.4ghz Cordless Phone Interference

    Im sorry to start another "cordless phone" thread but after much searching I cannot find a solid answer.

    I have a pain in the ass frequency hoping 2.4ghz Panasonic cordless phone. It uses a frequency range of 2406mhz to 2478mhz. My WRT54GS can operate between 2412mhz and 2462mhz, depending on the channel selected. So obviously my phone can walk all over my wireless signal and it usually does. About half the time a phone line is activated (using the phone) I will lose my wireless signal. The other half of the time, I get lucky with the frequency lottery and both signals can co-exist nicely. Or I can press the channel botton on the phone a few times until the wireless works but its a real pain in the ass because there is no easy way to permently set the phone frequency.

    My question is, Is there a 3rd party utility (ie. Sveasoft) that can force my wireless router to operate at a frequency outside its normal range? If I can get my wireless router to run at < 2406mhz (or > 2462mhz) it should completely avoid cordless phone signals, regardless of what channel the phone lands on. But Im not sure if my wireless cards (WPC54GS) can operate on a non standard frequency. I guess I could play the signal amplification game but seperating the wireless and phone frequencies makes more sense.

    I dont think any 3rd party firmware will help with the frequency problem. I have a 2.4ghz AT&T phone shown HERE. My daughter sits on the phone and IM's her friends from a laptop all hours of the day with no disconnects. When she's not on my wife is there with the phone glued to her ear. I have a 2 router setup, one as an AP and another as Client Bridge upstairs both set to channel 11. Never have had any issues yet, knock on wood. Could be just your phone.

    no 3rd party firmware will use any channel outside of the g spectrum as this would make it inoperable with the wireless clients. the WRT54G supports from 1-13 and so do most Wireless clients.

    you can change ALL the wireless routers and device you have and nothing will change. the problem is the Phones. the panasonic are known to cause problems.

    Just get yourself a new phone. I had a panasonic and it would overpower my wireless no matter where i was in the house until the battery discharged to 1/2 or less. Do yourself a favor and just get a different set, 5ghz will do but if you are concerned about cost then go with a 900mghz which are still readily available. But rather then spend countless hours wasting time trying to come up with something, save the headache and just get rid of the red headed step child of a phone.

    Also trying to operate your router outside the permitted frequencies may be illegal in some if not all of the different countries.
