Trouble with Nanostation M5-XW and SW

Dear maintainers.

First of all, very good work you're doing with the project and the forum. Lots of information and good advice in here, and very good reading material as well. Especially for me as a newbie to AREDN, there is a lot to learn and study.

I got myself three used Ubiquiti Nanostations M5 with hardware revision XW. They all work quite nicely with good throughput and stability with AirOS6 and also with a genuine openWRT installation With my local WLAN hotspot at home I'm getting max. throughput, modulation scheme MCS15 nearly constantly, FTP throughput around 6 MByte/s. Very decent.

Installing the latest works like a charm, however, the mesh building and once its established, its stability is very poor. First I thought I bough faulty hardware, but the hardware performs fine. Also, after a few Gigabytes of data, the mesh dies, the stations every now and then come to re-establish briefly, but no luck again. After power-cycling all stations, same game from the start.

I downgraded to use which installs ok but fails to save the first password change and never lets me go any further than that. Is this a known issue? Couldn't find any notice about that.

Next stop was release and I'm lucky the first time with AREDN software. Throughput in a peer-to-peer mesh is nearly as good as with AirOS and openWRT, mesh build-up is quick, stability and re-establishment are wonderful. More recent releases I haven't tried out yet.

Is already known to have issues at least with Nanostations XW, or am I the first to report, or may there be something I missed in setting them up? (Just doing it the normal way with tftp...). How can I support further investigation?

Cheers and 73, Andreas.

" the mesh building and once its established, its stability is very poor. "
Hi, Andreas:
Please further explain 'mesh building'.
Please further define 'stability'.
LQ/NLQ values would be a measure of quality.
TxMbps and SNR would be a measure of signal strength.
If all the AREDN devices are in/at the same location,
I recommend setting Distance to farthest node to 1 km. i.e. Not automatic (0 km).

73, Chuck
