I think the signal-quality indication is based upon the packet error
rate. (You ought to be able to verify this by looking at the CRC-error
counters.) You could have a great signal, but still get lots of errors
if you have high noise or interference, or if something is wrong with
the receiver or transmitter.
There's one other possibility. Just a wild guess.
Do you have the NIC and the AP very close together? (Hmmm, probably not
since your signal strength would probably be 100% if they were really
close together.) (Or is some other transmitter close to your AP?)
Does the signal quality improve if you increase the separation between
the NIC and the AP?
If it does, you might be overloading the front end of the receiver,
causing distortion, which can cause errors.
I have no experience with the Cisco 1200, so I don't know if it's
susceptible to this. My Cisco AP352 works fine even when my NIC is only
a couple feet away, but I figured it was worth a mention.
I hope this helps!
