only 176/176 data rate with AP3865 WDS

[Ronald_Dvorak]

Hi, we just prepare the installation of a WDS link with model AP3865 on both sites with 2x AO-5D23009N-5GHz-23dBi-9degree antenna per AP.

I've configured the APs for 80MHz, ac-strict, 3dbm tx power.

The APs are right now in the lab (in the same room) but we only get a data rate of 176/176.
We are running latest code on the controller.

Any idea... we thought that with 2 antennas per AP (instaed of 3) we'd reach MCS#9 - 2x2x2, NGI, VHT80 = 780mbs.

Here a screenshot of the report - it's the second WDS link....

Hi Doug, please have a look at GTAC case 01146766!

I took a look at the ticket, you will want to increase your TCP window size (use the max) and send multiple streams to get an average (start with 4 at once). I will update the ticket as well...

Matthias,

You would need to provide more info on the design, the above issue was resolved by changing the antenna diversity on a specific ap model. The speed may be limited based on the antenna types or settings used. I would suggest if you are seeing an issue, you contact the GTAC for further assistance.

Same issue - how can i tune up performance or troubleshoot that ? We uses V9.15.08 and AP 3715 (pre Test in a lab scenario).
