It may be a band frequency conflict

Submitted by Kerry Kobashi on Thu, 02/05/2009 - 12:13am.

The band frequency of the wireless router is likely interfering with the band frequency of your wireless telephone. Both are probably on the 2.4Ghz block.

You can handle this in one of three ways:

  1. Set the band frequency on the telephone console to be something other than the 2.4Ghz band
  2. Change the channel the router is on (more below)
  3. Buy a new wireless phone outside the 2.4Ghz band

If you decide to try the channel route, you can test this by starting at channel 1, and then calling your home telephone. If the line drops, move to the next channel on the router.

The various channel frequencies are:

  1. Channel 1 - 2.412Ghz
  2. Channel 2 - 2.417Ghz
  3. Channel 3 - 2.422Ghz
  4. Channel 4 - 2.427Ghz
  5. Channel 5 - 2.432Ghz
  6. Channel 6 - 2.437Ghz
  7. Channel 7 - 2.4422Ghz
  8. Channel 8 - 2.447Ghz
  9. Channel 9 - 2.452Ghz
  10. Channel 10 - 2.457Ghz
  11. Channel 11 - 2.462Ghz
  12. Channel 12 - 2.467Ghz (a)
  13. Channel 13 - 2.472Ghz (a)
  14. Channel 14 - 2.484Ghz (a, b)

Note:
a - not available in US
b - not available in Europe

As you can see, the frequency ranges are stepped up so it may be possible for you to get out of the band of your wireless phone. Try to choose one as farthest away from 2.45Ghz as possible to avoid conflict.

Hope this helps.

That was it! I moved it to channel 11 and dialed the telephone. My Internet connection didn't drop. Wow man you saved me some money. I was almost going to get a new telephone that would have set me back a $100. You rock! Glad I found this place! Thanks!
