Wanted to follow up on this one as well. Changing to TDD PTP appears
to have done the trick its been up for 5 days now with no issues.
Thanks for all the idea’s everyone.

Steve,
I don’t think I said. Sorry about that. Its 2.4 on 20mhz channel.
Upgrading to 3.5.2 did not work. However, changed it to TDD PTP and
its going on 20 hours stable so far.
As with most things time will tell.
Thanks everyone.

My eptp link was 2.4.3 with the issue for sure
I had a ptmp AP (flexible) 2.5.1 that had an issue where no one
could associate until I rebooted
I would think in 2.6.x it was resolved. I haven't seen any issues
myself since 2.6.x.

Josh,
Was the bug in 2.6.1.x? I will certainly upgrade but just
wondering how long this has been around.
Thanks everyone.

There was a bug that caused it to hang way back in the day
(when the Force 200 and eptp came out). They patched my link
and it quit dying entirely, but I think it was some quick reset.
There's a known bug in 3.5.1 that's semi-resolved in 3.5.2
relating to this, but it is not 100% fixed from what I'm
told. Upgrade to 3.5.2 and when there's a new release you'll
want to upgrade when you can.

I've seen that happen before, but I can't remember what we
did to fix it... I think we may have had to replace the
radio. I can't remember if it was a PTP or PTMP situation,
either... it was a while ago.
It might be worth switching it to TDD PTP mode instead,
and see if that helps.

Yes de-registering the link does make the link start
passing traffic again although it seems a lot shorter
lived so far. Only lasted an hour.

I don’t know. I will report back after trying it.
Thanks for the idea.

Does it start working again if you just de-register
the link, instead of rebooting the radio(s)?

Dave,
I have not seems like such a strange issue I
didn’t have much faith in tech support. My
experience is the list seems to have better info
on these odd issues. One side of this link
requires snow shoes to get to so I am trying to
avoid replacement if at all possible.
Thanks,
Brandon

Have you placed a support request to cambium yet?

Looking to see if anyone has experienced a
similar issue to this:
We have a force 200 backhaul on a small
bridged network.
Several times a day now it stops passing most
traffic. It can be humming along at 25mbps
down and 5mbps upload and then drop down to
2mbps download and less than 1mbps upload.
Downlink RSSI -65 dBm
Downlink SRN 30 dB
Uplink MCS MCS 14
Downlink MCS MCS15
All remains constant during this time.
The ping falls apart during this time between
the AP and the SM although pings through the
network to the SM or through the network from
the AM are both fine it’s just between them
that starts to drop packets.
The units show heavy retransmission packets
from the moment the link is brought online
around 40% at times.
At this point I would assume noise is the issue.
*_But here is the odd part I would like some
help with_*. Rebooting the link fixes the
issue but leaving the link alone does not. It
will stay “broken” until one or both sides of
the link are rebooted. Then it works perfectly
for a time and falls apart again.
Current firmware is 3.5.1 but we have run it
on 2.6.1.1 and 3.3 with similar results.
Any thoughts on how to troubleshot this one
would be awesome.
Best Regards.
