Since firmware 6.1.8 there is new calculation of the CCQ value.
1. what exactly was changed in the way how CCQ is calculated?
2. with old algo, CCQ over 95% was indicating a good link, what is the number now?

It is not just the CCQ... it is also the TX/RX rates also.
Had a service call.
Customer had little or no service at all.
2Ghz. PB states -73dB, 50-60%CCQ, TX @ 3.25mbps (= broken)
Cannot even login to CPE from AP it is so bad.
Has 6.1.8 firmware.
Swap for a NanostationM.
-72dB 90%+CCQ, TX @ 65mbps.
Touched nothing , except Update software from 6.1.7 to 6.1.8
Back to little to no internet and CCQ=50%, TX=3.25Mbps specs again = broken.
This is not just a "re-calculation" ... this is buggy-broken firmware.

@PeterK2 CCQ calculation and its reporting were fixed.
CCQ reporting does not impact link performance. Performance deterioration or other link problems could be impacted by other things that should be investigated.

of course, only thing I want to know is what is doing the new algo and what are safe numbers, so you are saying in next firmware again 95% and higher number will means a good link?

I understand that "calculation and its reporting were fixed" means it will be back in old numbers in 6.1.9.
But that is not important, just tell us, as years until now around 95% of CCQ means stable link? thanks
