how do you troubleshoot wireless connectivity problem?

[bleuless]

when it works its great, when nothing can connect at all! and in the past i seem to be able to fix it by randomly toggling some setting in the wireless router (trendnet TEW-431BRP).

i am not sure if it equipment incompatibility, or the stupid router, or air interference.

i tried multiple different vendor wireless adapter clients, the results are not conclusive. so i know its not the clients, but incompatibility may be the case.

i know its not config because a working config would work one day not the next. and when it does work, it stays up as long as i leave the pc on/connected.

with regular ethernet, i can set up a sniffer, but wireless... what do you do when it won't even connect? the survey shows it sees it, but it won't connect to it as if the pw is wrong or something... i don't want to go buy another router if it turns out to be air interference (even with full bar with my signal booster). i am posting this at 6:30am from about 1:30 hour of frustration.

Easiest way is to change channels to 1, 6, 11 and see which one is the most stable. Fiddling with settings on the router usually leads to creating a configuration problem - just because it works one day and not the next does not mean it isn't configuration related.

Second step is to remove all security/encryption, then try different channels. If this works then you know it is a configuration problem. Also just because you have a strong signal doesn't mean you don't have a tremendous amount of interferrence/noise.
