New CCQ algo in fw 6.1.8

[ Edited ]

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?

 

thanks

i'd love to know also because the link works the same but CCQ is way lower

@UBNT-Dalia do you have a short summary of the calculation change to hand?

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.
Works great.
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.

I don't think I've seen the actual data rates change due to v6.1.8 vs v6.1.7. Do you have support files from these units?

@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'm not sure what you mean by 'in next firmware again 95% and higher number'. We aren't planning to change the CCQ calculation again.

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

There are no plans to revert to the old CCQ method in v6.1.9.
