I suspect I have an transmit and receive mismatch between the client and the AP - the client can hear the AP fine, but does not seem to be able to push data back. Is there a stat that I can look at to verify the Tx and Rx differences?
Look at the RSS on the client side then look at the RSS from the server (wireless side). What are the differentiators. Also, what is the radio dBm level set to? If it's to high, you might just create that scenario. I tend to limit both 2.4 and 5 Ghz to 14-15 dBm.
