Re: effect of disabling burst-time

Correct. Use with caution with point to multi point setups, as all other radios are not being accessed for the time of the burst. If you set the burst to 1 second you will have at least a 1 second latency before the next radio is sent data. Using Nstreme will likely provide better results.

Re: effect of disabling burst-time

Burst time will allow continuous transmission for the set duration. Not so bad on a P2P but can cause problems on P2MP as no other radios can communicate until the transmission is complete. This could cause latency issues and enable some clients to "hog" the AP traffic at the expense of others.

no not always. There is often more noise/interference/fade at one end of a link then the other so one side may need to do more retransmits then the traffic going other way.

You could also have an interference problem. The chip sets are limited in what they "see" and many modulations will not show up. Also look for lower then normal signal strength, high CCQ and do a usage scan. If any of these are not normal it is likely interference rather then a software issue.
