channel problem 5 6 7 8

Wierd problem.
I bought a wrt54g today and set it up on channel 6, my laptop with a
builtin intel 2200bg wouldnt connect.
It is running XP SP1. I put the wrt54g on channel 1 and 11 and it
worked. channel 5, 6 ,7 and 8 would not work but 4 and 9 detected the
wrt54g but would not connect. I suspected the wrt54g but I have a
wap54g (that I usually run on 11) and did the same test and had the
same results with my laptop. I figured my laptop card was at fault so
I put in a oninoco card and it also had the same results. Any ideas?

Sounds like interference in your area, don't use those channels.

Both the WRT54G (assuming thats a wireless router) and the WAP54G (assuming
thats an AP) won't work with channels 5 through 8 -- with either of the two
wireless laptop (built-in or the Orinoco card)...

Hmm. Something is in the air. I take it that its probably not outside
SSIDs, or you would have already noted that easily. Have ya tried running
Netstumbler on the laptop to see how bad the SNR is on the those channels
while the router or AP is broadcasting channels 5 to 8.? Might be able to
track it down doing that. Common sources of home interference (2.4 Ghz) can
come from cordless phones, microwave ovens, fish aquariums, security
systems, baby monitors, garage door opens, you name it.

I might be mistaken, but isn't there a "spectrum analyzer"-type program
available for Orinoco cards? I seem to recall coming across one
(downloadable) at some point and was interested in it until noting that it
wouldn't work with any of my hardware. By "spec annie", I mean that the
program will display any signal received in the card's band -- regardless of
what scheme it is using.

Any suspect commercial/industrial sources outside your home? Hopefully this
won't be the case, as really won't be able to do anything short of wrapping
your house in aluminum foil. :/

Keep us posted on what you find out as this is an interesting topic.

Are you using Super "G" Mode? If so I understand that super g will
only work on a certain channel.
This is here say buy it comes from a reliable source who I have known
for years. I do not use Super G...so I do not know what channel it
uses..but he said his would only work on channel 11 or something like
that...it was in his documentation.

I look forward to hearing what fixes your problem.

I tested another laptop and it had the same issue. Netstumbler shows
my AP on channel 6 but it drops in and out. I used my Spectrum card
and snoop
and there is a fairly high signal around channel 6. I just didnt
expect it cause
i live in the boonies of arkansas and not that many close neighbors.
Maybe
someone put in a wisp but I would expect to see an SSID if thats the
case or
my neigbors are brighter than I thought. Everything looked normal
on Netstumbler comparing to other channels except the SNR faded in and
out
along with the AP active, Inactive.

Do you have 2.4 freq. portable phones, microwave, baby monitor, etc all
these devices use the 2.4 freq. that your router uses. The 2.4 range is a
shared freq., if you want less interference get a router that uses the A
freq. it uses the 5.8 freq.

No, I have nothing in the house that could cause it. It must be an
outside source.
I can use 1 or 11 and it works fine so its not a problem its just that
I had bought
a new wrt54g and was checking it out when I discovered 6 wouldnt work
so
I thought it might be the new box.

Interesting. A WISP was in the back of my mind when I wrote my previous
message. Interesting how these might come into play with private home
networks down the road.

Could be coming from an (non communications related) industrial source as
well. Know of any local HAM groups? I bet they would be more than happy
to help track down whatever this RF source is.
