It's this one:

But I've tried another d-link and a linksys router and all behaved
exactly the same way.
The card is a linksys wmp54g. I'm using xp, but I can't remember the
service pack level off hand. All of the machines in the house are xp.
They have different boards (mostly netgear), all go down including the
tivo.
Is the 15ft line of sight or is there furniture in the way?
Line of sight.
How often does it disappear and for how long? This is not a trivial
question. If it follows a pattern, it will help identify a possible
source of interference such as 2.4GHz cordless phones, microwave
ovens, and other wireless networks. Do you have any other 2.4GHz
wireless devices in the area?
It goes down maybe twice a week. When it happens during the day, my
wife gives up on it. Then when I get home, I disable/enable and it
comes right back up. Other times when it happens, there's nothing to
connect to since it doesn't show up in the list. I just keep hitting
refresh. Sometimes it comes back, sometimes not.
It's probably not the microwave since we use that a lot more than it
goes down. We have a cordless phone, but iirc, it's not 2.4ghz. And
using or not using the phone doesn't seem to have an affect. There's
no other wireless devices in our house. If there is interference, it's
not from us.
Moving the antenae has no affect, nor does changing the channel.
Bingo. Interference, probably at the access point. Do you have it
located in a window where it can see the crud from the rest of the
neighborhood?
No, it's accross the room on a book case. Although it still manages to
pick up *a lot* of other networks when it's working. Like 10-12 other
networks. When it goes down, I can see 2 or 3, none of them mine.
That leaves cordless phones,
Would the neighbor's phone be close enough for this? it's a tract
neighborhood with maybe 20 feet between the houses.
microwave ovens,
same thing. it's not ours.
industrial
dryers,
like in a laudromat? we don't have any. And our dryer is gas-powered
and runs constantly.
video links,
like a wireless security camera? I don't have anything like that.
maybe the neighbors do.
and frequeny hopping devices.
I'm not sure what this would be. Car transmitters or garage door
openers? Those work in bursts. I would think they could knock me off,
then I could get back on. Sometimes, I'm kept off for 20 minutes or
more.
Definately try moving the access point to a
more "protected" location.
I'm not sure where I would put it.
The guy at besy buy (yuk) suggested switching to a different "country"
that has channels other than 1-11. My card supports this, but it looks
like the access point doesn't.
It's been behaving lately, but now comcast is flaky. I'll see if I can
gather more intel next time it goes down.
