L11UG "stalls" at basic rates in PtMP (ROS 7.16)

[Bomber67]

At a couple of occasions I have been notified by customers of poor wireless performance, and the reason turned out to be the AP being stuck at 6 or 7.3 Mbps. It looks like it does when configuration.distance is omitted for longer links, rates do not start “climbing” when pulling traffic.

This has happened after AP has been running for weeks, and I have seen it in 2 different setups:

1. All AX clients (L11UG) with ROS 7.15.x
2. All AC clients (RB922) with ROS 6.45 (yes I know it’s old, they’re due for replacement)
   Signal in the 50s/60s, configuration.distance param properly set.

After an upgrade/reboot rates are back.
So what is the reason for this?

Interesting, I still don’t know of any success stories using the L11UG in WISP or long-distance environments. Could someone shed some light on this topic and help us configure it to replace our old AC access points?

Yes this is an interesting topic.
My impression is that ax performs better than ac, that noise suppression is better and that it is able to maintain god/top rates at lower signal levels, 573 Mbps at 40 MHz even a bit down in the 60s
Even if it’s 802.11 afaik it handles the “hidden node” problem, which ac does not.

But I miss the ability to control and monitor the connections…looks like it all is taken care of by the wireless chipset. You set a few params, it connects and works but you don’t see much about what’s happening.

Hi Bomber. I’ve been trying for a few months to find feedback on new AX devices for use in a WISP setup, but I haven’t been able to find much information until now. Your post is like a beacon in the desert to me!

I wanted to ask, what APs do you use, and what antenna do you pair with your L11UGs? Do you think this setup is usable for a WISP?

Thanks!

The situation is a little challenging.
Almost a year ago MT informed their distributors that the Disc Lite ac - the “goto” CPE device for many WISPs including me - was discontinued, without releasing its AX successor, leaving a “hole” in their product portfolio.

Nobody can give a sane answer regarding when an integrated AX client will be available.

I am running a small WISP and needed to upgrade to AX/60G to increase speed.
I could not wait for the “Disc AX” or whatever it will be, so until now I have used RF Elements starterdish 21 and Jirous Gentlebox JCE-320 MCX.

For APs I have used RFE Asymmetric Horns, mostly 60 degrees.
On the models with twistport adapter, radio swap is very easy.
