Linksys WRT54G and 2.4G telephones.

Newbie predicament:
I've been offered a Linksys WRT54G system for free, but I just upgraded my
2.4g phone system to 8 handsets. I know they are supposed to interfere with
each other but was told it would work ok as long as the router and the phone
base unit (and handset?) weren't in the same room. Anyone have any advise on
the issue? It would be prohibitively expensive to replace the phones. Do
they interfere simply by being powered up, or only when a call comes in (or
goes out)?

TIA.

That's 50% true. However, the handset and the computer can't be in
the same area either. That means that yacking on the wireless phone
at the same time as you're pounding on your wireless laptop is not
going to work.

Different models have different problems. If it's an FM 2.4GHz
(non-spread spectrum) type of phone, it will probably work just fine
in the same room as the WRT54G. If it's a DSSS (direct sequence
spread spectrum) cordless phone, then it will slow down the wireless,
but not kill it. If it's a FHSS (frequency hopping spread spectrum)
cordless phone, it will kill the wireless. Since you didn't bother
specifying the maker and model number of your phone, I can't offer any
additional guesswork.

Well, up until about a month ago, I would have said that they only
interfere when being used. My Panasonic GigaRange KX-TG2257 2.4GHz
phone is probably DSSS and only causes problems when I'm yacking on
the phone. However, there has been one report in this newsgroup that
there are some models where the phone base constantly transmits, even
when there is no phone conversation. I'm not sure I believe this, but
it is possible.

>TIA.

Standard answer: Try it and see if it works. If there's a problem,
it will be obvious.

i got a wrt54g and some panasonic 2.4ghz phones

occasionally when a call is coming in or being placed my wireless connection
dies about 10% of the time

because the phone will use the same channel the router is using.occasionally

the router and the phone base are rather far away

Sorry I left out pertinent info. The base unit is a Uniden model
DCX5285, the handsets are Uniden model DCT520. It is a DSS (Digital
Spread Spectrum)per the spec sheet, nothing about DSSS.

Just downloaded the manual. It's a Frequency Hopper. That seems to kill
the whole plan.

Typo error. It's a DCT5285. DSS is the buzzword invented by the
industry to hide the technology behind the device. One would not want
to "confuse" the consumer. If it says frequency hopper, it probably
clobbers the entire 2.4Ghz band. I still think it's worth trying to
see how bad it is. It just might be tolerable. However, with 8
phones scattered around the house, finding an optimum location for the
WRT54G is going to be a problem.

Definately worth trying for a couple of reasons. One the frequency band that
is used is not exactly the same between the two systems, two, I have 4
handsets and WiFi and suffer no problems.
Furthermore my previous BT set did not interfer nor does my brothers system
interfer.

Keep your receipts and open the boxes carefully with ripping them, but give
it a go
