3.6 Km Ptp Link -- bad RX ccq and BW [SOLVED]

Good morning I was wondering if someone could give me any suggestions to improve my situation. PtP.png In theory, I should have a signal strength of around -65db. The screenshot can only show a shot, but the RX values actually keep changing (ccq ranges from 29% to 70% and bw can go up to 86.6Mbs) TX...

Re: 911G-5HPacD crash/reboot when sending 1M+ over wlan1

Thanks again to all of you guys. I am not an expert and did not know about the existence of the "/system health" command . And it looks like the power supply was somewhat damaged. Failed unit (station): fan-switch: on fan-on-threshold: 40C voltage: 7.5V temperature: 41C Working unit (peer AP): fan-s...

Re: 911G-5HPacD crash/reboot when sending 1M+ over wlan1

Thank you guys .

Currently the unit is powered by an 18v 1A power supply. But it could also be damaged.
I will give it a try with a PS with more Amps.
I also have a 24v 0.8 A that i could try, but i guess what matters the most are the Amps .

Re: 911G-5HPacD crash/reboot when sending 1M+ over wlan1

Today the issue resurfaced. Is there any way to understand what is causing the issue? I logged to disk but there is nothing shown there. Is there a core dump that i can send to MT for analysis? I need to know if this is a hardware issue or i can workaround it in any way. Anyone from MT that could an...

Re: 911G-5HPacD crash/reboot when sending 1M+ over wlan1

Going crazy. I was trying to troubleshoot further so I thought i gave it a try and set tx-chains=0,1 with rx-chains=0 (or 1) No issues. After that i was about to reproduce for having a look at the disk logs, so I have set tx-chains=0,1 and rx-chains=0,1. Surprise issue was gone. what the hell ... gi...

If i enable both tx chains ( tx-chains=0,1) the issue is reproducible. If I only use 0 or 1 all is fine. Once again, it was working fine until yester...
