speestream wireless/siemens phone interference

I am having trouble with interference between my wireless network and
my 2.4. ghz phone system.

I have a Speestream 2624 wireless router and 2 pc's with Dlink DWL
520+ pc cards. I also have a Siemens 2402 2.4 ghz phone system with
several handsets throughout my house.

The base for the phone system is on the 2nd floor of my 2-story house.
The router is located in the basement.

Most of the time, everything works fine, but I seem to get random
interference while I am talking on the phone. If I literally hit the
phone, the problem goes away (at least until the next random
incident). I have tried changing the channel on the router from 1 to
6 to 11, but the problem persists.

Is there any solution to this other than buying a new wireless setup
or a new phone system?

Thanks.

Your wireless setup has nothing to do with it. WiFi uses DSSS "Direct
Sequence Spread Spectrum" and many 2.4Ghz phones uses FHSS "Frequency
Hopping Spread Spectrum" which allows multiple handsets. Wifi DSSS receivers
does not seem to like FHSS transmissions nearby.
The stronger phone transmissions of FHSS, changing from one frequency to
another several times a second, is not well accepted by the WiFi receivers.

You could try digital "only" 2.4Ghz phones (no DSS or FHSS or Spread
Spectrum labelling, Panasonic got few of these). They transmit only at two
frequencies (transmit and receive) at low power ~10mW.
The drawback: limited or no support for multiple handsets, maximum two as
far as I know. Read the specs carefully.
