I’m hoping someone might be able to help me out here. I’ve set up an RB/411 broadcast with a Ubiquiti XR9 900MHz radio card for a non-line of sight rebroadcast. I’m getting excellent signals everywhere I’ve tested (not behind hills of course 
) ranging between -40 up close and -75 or so further away. The problem I’m running into is that the link gets dropped every few seconds to few minutes. One really odd thing I noticed was the signal strength was showing at -2147483647 (or so) very briefly before either correcting itself to a valid signal strength or dropping the connection. One other odd thing was that it appeared to work perfectly fine inside the building where the rebroadcast is located, at approximately 70 feet away, yet another 30 feet outside, dropped connections all the time.
We’ve got another 900MHz rebroadcast running identical equipment without a problem, though it’s running a slightly older firmware. The rebroadcast that works fine is running RouterOS 3.10, whereas the problematic one is running 3.22. The steps I’ve used to configure the rebroadcasts can be found here. It has worked before, just not sure why not now.
Any help and/or suggestions would be more than appreciated. Thanks in advance!
Regards,
John
