My wifi used to work, then got flaky, now never works

I've already visited http://ezlan.net/ but no joy.

MY system uses windows 2000 pro, and a Hawking wifi PCI card. No WEP
security.

The wifi used to work fine. Then a few weeks ago it tended to get
flaky, it would drop frequently a connection to the access point even
though the signal strength was the same as before. Now, it can "see"
the AP, same signal strength, seems to try to connect, but the
connection looks to not achieve itself after a brief handshake of sorts.

I looked at http://ezlan.net/ but even though it looks to be
comprehensive, no joy. I tried turning off virusscan (MacAfee) but no
joy. I tried reinstalling the wifi board drivers, no joy. Net Stumbler
sees all the neighbor's networks just like it did when the wifi worked,
so the antenna must be okay. As far as I can tell, win2000pro doesn't
have wireless zero configuration.

Baffled, any help TIA

Does NetStumbler show your SNR, in addition to Signal Level? Is SNR the same?
You're sure that there are no new neighbours? Maybe some that come and go?

What changes did you make, just before "a few weeks ago"? Have you gotten the
latest drivers for the Hawking? Maybe firmware for the WiFi router?

I had an external Hawking wifi booster (preamp and power amp) that went
bad. It could pass received signals but not transmit my outgoing
signal. Removed it and now I can connect. So there was nothing wrong
with any SW or HW inside the PC.
