MikroTik

Trying to run an SR2 and SR9 in a routerboard 153.
Getting random reboots around 3 - 5 times a week.

Noticing some clients signal levels are changing upwards
of 20db at time. one minute they are -60 and next around -80db.
There are days where the signal will not change at all, usually for the worse. This is a very quiet rural area so i don't believe interference
is the culprit. my scans show nothing.

We have recrimped all ends several times. Antennas are good.
Running 48v POE about 75' on outdoor cat 5.

any suggestions?

If you are seeing the problem on the SR9 side it sounds like a classic case of interference. We **regularly** see interference manifested as a signal drop on the SR9/MT combo.

Don't depend on your scans unless you are doing them with a spectrum analyser We have very poor luck so far picking up any non-802.11 900 other than a Trango 900 running 15' away, but have very good visibility of other MTs at 30km+ distance.

Even in deep rural areas you could have a high powered paging transmitter close enough to cause a world of hurt. A good maxim in 900 is you are more likely to have interference than not.

No, it's on the 2.4. We aren't using 900 in the area yet. Future use.
When the weather warms up a bit I am going to get a climber up to
pull the SR9 out and see if that fixes the problem.
I have done the frequency scan that is in mikrotik.
2.4 is showing clear.

Just curious if the sr9 and sr2 were pulling too much power to cause
the RB153 to reboot and drop signal.

we're having the same problem

sr9 and a cm9 seem to be ok.
soon as we add a rb52 or another cm9, boom... reboots within minutes.
