SMs dropping off randomly

Hello

So we have finished our second tower we have put all all e pmp 1000 2.4 sector aps, all running 2.4

I have old canopy 2.4 and ubquity 2.4 in certain areas

We are running the sectors on a 10mhz channel

and SMs in the 10mhz channel to avoid interference from my other equipment

I am the only ISP in the area so don't need to worry about other bands.

After we swap out the SMs radio to new it is working flawlessly, as we add more SMs to a certain AP it seems some are dropping off, we have sms that are 200 feet away from the tower. Signal strengths on each smĀ  looks fine.

Just wondering if anyone had a similar issue, or em i not setting up my new SMs properly.

Hi tnner,

Could you please provide System Log from AP and SM which are experiencing that issue.

Reason of disconnect should help to find what is causing the issue.

Thank you.

Seems its like a sync issue

My SMs will drop off, i turned the GPS to internal to see if that would help.

SM side

2477mhz

10mhz channel, i am in the middle of changed out my canopy 2.4 and ubquity 2.4 aps, i set the seperation right so they shouldn't be interfering.

Is this AP facing another epmp AP on a different tower ? You may have your front and back options set incorrectly.

Also try aiming your gps pucks so the wireless symbol is facing up, towards the sky, not flat. You could be to low of a signal to your gps. In another post recently about GPS sync being dropped I helped another gentlemen with that issue. Also set your hold off time to 300 so it has a little time to recover if it does get knocked down.
