2.4 Ghz phone interference

Greetings,
I live in an apartment building and have had a flawless running wireless
network for months. Recently I've been getting dropped connections, which is
extremely frustrating. My guess is that a neighbour has picked up a 2.4 Ghz
phone, and when they use it, it zaps my connection.
I've tried changing the channel from 6, to 11, to 1. No difference. (I'm
using a linksys wrt54g btw)
Is is possible that a neighbours phone could cause this much interference?
How close does the phone have to be to cause interference? Short of breaking
down the door and beating their phone with a hammer (or asking them to get a
different one), what can I do about it?
Thanks!

you can try reducing the fragmentation threshold and RTS/CTS threshold

I set mine to 2321 and 2309 respectively and stabilised the network
considerably without affecting performance very much.

This applies to all parts of the network. Router,cards etc.

But the interference may be too severe for this to solve the problem. YMMV.

My guess is that if you are using Windows XP, it is more likely that someone
has added a wireless network. Do you see any new SSIDs showing up in your
wireless networks? If that is the case, there are several things you can
do.

-- Be sure your SSID is unique.
-- Be sure you are broadcasting your SSID (Windows XP has a problem if it is
not in this case)
-- Disable the option to allow Windows to manage your wireless settings and
stop and disable the wireless zero configuration service. By doing this
assumes that your wireless adapter has its own configuration program that
you will need to use.

Also, I meant to mention that you could try a different channel. Try 1, 6,
or 11. These are the only non-overlapping channels.

I am using XP Pro. When I scan for wireless networks, mine is the only one
that appears. Would another network interfere if they weren't broadcasting
their SSID? I am broadcasting mine, and it is unique.
Do you have more details regarding the wireless zero thing... I've never
heard of it.

Hi Jeff,
They are non overlapping when used with each other, but so are 2 and
7. The trick is to find a channel that does not overlap with what the
other 2.4GHz device is using. So if the other network is using channel
3, you'd have to use 8.

Do a google newsgroup search of this group for "wireless zero
configuration". You will see plenty of postings for it. You could add my
name to the search as well. :-)

Hmmm..I wonder what type of phone your neighbor has.

I have a 2.4G phone system also and I get no interference w/ my laptop
and pda streaming data and music. I have the following wireless settings:

beacon int: 100ms
rts thres: 2346
frag: 2346
dtim int: 1
short preamble, no broadcast, auto cts mode, superg w/o turbo 802.11g
only mode off.

I use dhcp and static address w/ mac filtering, but that may not affect
your situation.

Good luck-I hope you get it resolved; this networking stuff is fun when
you get it to work;-)
