Re: [AFMUG] odd Force 200 backhaul issues.
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 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.

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

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. Brandon Yuchasz -- Error!
