Last week I posted concerns about our AF24 putting out these FCS errors after a firmware upgrade from 1.5 to 2.0. I noticed them in the TIK router running 6.x.
For ‘unknown’ reasons, no one could explain why the TIK router would not sync up at 1Gb and be stable with the Air fiber attached. The resolution was to run 100Mb. UBNT wanted me to do ALL the things we did last year. (swap cable, terminations, grounding, POE etc.) Hah! That was all done including a different Air fiber. Sorry but that is not the problem guys! Upgraded to the BETA firmware and MOST of these errors cleared but still showed randomly at times. Upgraded TIK to 6.2 same issue….actually got real bad… including some customers indicating the network had slowed. We resolved the errors showing up on the TIK Ethernet side by doing all these things PLUS enabling the Flow Control on both the UBNT and TIK router. No errors showing up but some customers SWEAR things have slowed down now. I haven’t test from the other end yet. There is no reason it should be slow since now we have got this working on 1GB. I am willing to lose some money that if we reverse those changes and put a 1GB switches in between the air fiber and TIK router all will clear. WHY does this industry put up with these silly quirks is beyond me. VERY frustrating. I don’t think either UBNT or MT really knows who is at fault here.

I had to run 2.2-beta3 on the AF5s since it has DFS/RADAR improvements. I've had a 3.4 mile link up running DFS band for a couple weeks and it has been pretty stable pushing about 100Mbps. I would kill for a 5.1-5.3GHz AF5. Anyway... since Chuck seems to think it's MikroTik, I will pull out a spare AF24 and see if I get errors on either of my two managed switches in the office.

The interface FCS error counter is zero (or near zero), and each time I did Tools->Discovery, the FCS counter would increment by between 5 and 15. Our AF24s are otherwise working fine. We upgraded to 1.5 to get SNMP, and haven't had the need to upgrade beyond that. George tends to operate a bit closer to the bleeding edge than I'm comfortable with. bp <part-15@SkylineBroadbandService> On 11/7/2014 8:44 AM, Chuck Macenski via Af wrote: You also have issues when connected to Microtik?

I have some AF24's on 2.0 and AF5's on 2.2-beta3. They work fine. If I do a Tools > Discovery, the MT ethernet counters on both sides will increment FCS and Code errors. Same thing happens if I run some pings between the radios (not router to router, radio to radio). I'm guessing this because of the switching method the AF's use (cut-through?).
