Is there a way to reduce interferance from Cordless phones?

[nikemen]

So, I upgraded our phones to the new Uniden TRU-8888 phones, all 5.8 ghz phones. For the most part, I like these phones.

The real reason I went with them was to reduce, or eliminate interferance with my 802.11 b/g network.

But, I have found that the phones DO create interferance. When I am on the network and a call comes in, there is no question there is a pause in connectivity.

When I am doing a file transfer from the mail network, and make a call, BOOM I can see the network connection stop, slow or die.

Ending the call brings the connection back.

If I have a phone connection and try to make a network connection I either don't get a connection, or it takes a LONG time to negotiate. USually, NO connection.

Could it be the A side of the IBM A/b?G card? Is there a way to shut off this side of the card to test this?

Is there anything one can do to eliminate this? I thought that getting away from 2.4 gHz was going to be a cure all.

any thoughts or experience would be MOST appreciated.

Wow, no responses, I guess that means that there are no issues, nobody has any problems like this?

Or, some of use wireless networking but don't need or have cordless phones. ... JDHurst

That's odd.

I have been through several different iterations of 2.4Ghz phones in my home in an effort to stop interference with my network. Several years ago I set up an 802.11 network using Raylink cards running at 2 MBps and had lots of problems with interference between the WLAN and the phones --- every time someone used a phone things went haywire. I changed phone brands twice in an effort to get rid of it and along the way changed the WLAN to 802.11B using Lucent/Orinoco cards but continued to have problems with both the WLAN and the phones.

I ended up with some Panasonics on 2.4Ghz and the problems seemed to be reduced to only occasional interference. I later implemented a dual 802.11A/B network with a dual band D-Link router in an effort to move the WLAN away from the phones completely.

Two members of my family have notebooks and a desktop that have 802.11A PCMCIA cards and have never experienced any problems to or from the phones. My wife has a Dell notebook with 801.11B and has never reported any problem to me. My T-40 has both 11A/B and sometimes it selects 802.11B rather than the 11A network --- but even then I've never seen any interference FROM the phones.

I say FROM the phones because before switching to the 11A WLAN I occasionally had really poor reception/interference/breakup on the phones (even the Panasonics) that I suspect may be due to the network, but never the other way around.

But with all the wireless phones, WLANs, microwave ovens, security systems, etc., in the neighborhood I'd be hard pressed to say where the interference was coming from at any given time. Sometimes it amazes me that anything works with all the RF 'racket' going on

I have same issue with 802.11b before.. change your 802.11b channel may help

But,

shouldn't they be completly on differant frequencies?

Some phones work at the same frequency as some of the Wi-Fi hardware. I.e. G works at 2.4 GHz - Same as some newer wireless phones. B at 900 MHz - Same as some older phones.

If you know for a fact, that you are getting interference, change the channel on both devices. I.e. Fix channel 11 for Wi-Fi and 6 for you phone. You have to play around to find the optimum setup.

On side note: the standard 802.11 a/b/g, is quite complex and is only the Transport Layer for the OSI model.
