60g Nray random lockup

RouterOS Wireless Networking

Hello!

Do you guys had a problem with a pair of nray that see each other BUT wont establish a link until you reboot the ap nor station side?
I have a link that do that. It works like a charm for 10-15 days, something 2-3 months sometimes few days , then the link goes down. I some cases, I can still scan from the station and I see the ssid, but it wont connect back. The only fixe I found is to reboot the ap or somethime both radios.

WHAT I DID :

I tried to swap radios
Turning off interfaces
different FW
We also changed the AP for a wap60
6.47.10 station and 6.49.6 the ap

We have watchdog setup in the AP. And it reboot now by itself. But now we have to manually reboot the cpe side. It’s very weird.
Someone can help me ?


MORE DETAILS :
Stable current at each side, one side is a DC/DC setup with AGM batt and meanwell PSU, the other side (ap side) is a UPS cyberpower 1500va. So we have stable power source.
150M from st to ap, with a good signal well aimed, on channel 4.5 in a clear LOS.
We use this link to transport FTTH modem data to a router.

Hello
never had such a problem, but if you want an auto-reboot use watchdog to reboot it automaticaly

next v7 beta version will have potential fix for this issue.

Do you know the cause of this behaviour? We have dozen of nray link in production since months/years and only this specific link has this trouble. We even replaced both nray and tried to swap a nray by a wap60.

Knowing the cause would help to understand.


Thank you

this may happen in rare occasions if link has been lost for significant time slot and from AP side.

Do you think trying the lastest ROs7 version a good idea?

It looks like its related to or area. Since we swap both radios and we still have this problem. And it happens only on this link.
