interference, distance, more clients on AP, client chose to remain connected to weaker AP rather than roam to stronger signal (they do that and it's the cleints decision), connected initial data rate unsustainable so dropped to sustainable rate...probably other reasons but that'll do for a start.

Be pleased you are connecting at 140!
A solid reliable connection is far more important than maximising throughput.

===2nd thoughts====
After a reread I might be missing your intention. Please provide more info about the speed drop, ie what device or widget is reporting it.

Still not enough useful info.

What device is connecting to what device at what speed and where is this being reported (zd, ap, client)?

Remote possibility: Are you using mesh feature to connect AP to ZD (so no wired connection, this cuts throughput in half)?

90% of the time, the answer is Client SNR is directly related to Distance from the AP.
Higher RSSI, closer to the AP, translates to highest throughput. Try analyzing your
client link thoughput at near and far distances, and you will likely see this.

Hi Thanks for your Response ....Client is seated below the Access Point its not more than 5 feet .. also only one person connected to the Ap

Hi

its happening bcos of dynamic rate selection...

DRS is up-shifting and downshifting for rate optimization and improved performance. The algorithms used for dynamic rate switching are proprietary and are defined by radio card manufacturers. Most vendors base DRS on receive signal strength indicator (RSSI) thresholds, packet error rates, and retransmissions. Because vendors implement DRS differently, you may have two different vendor client cards at the same location, while one is communicating wit the access point at 11 Mbps and the other is communicating at 2 Mbps.

there is nothing much you can do as it is something well thought by WNIC driver to run at 140 MBPS at that location ir-respective of location or how far it is from AP.
