*** I was directed to the mailing list and kindly ask you to have a look, Thank 
you! ***

Hi,

I've now waited a long time to observe why my Archer C7 v2 and v5 units got bad 
performance on 2.4 GHz and sometimes complete crash of the WiFi drivers while 
the LAN interfaces are still working.

It all seems to boil down to OpenWrt's decision to include ath10k-ct drivers 
instead of ath10k (non-ct) drivers since 19.07.x releases.

Since then, many users including me according to the below referenced topics 
have the same issues, e.g.:

2.4 GHz download speed is capped around 10 MBit/sec.
ath10k driver crashes, requiring "rmmod ath10k-pci; sleep 10; insmod 
ath10k-pci;" or "reboot" to make the router work again.
5 GHz max bandwidth is a lot slower than with non-ct drivers, but still okay
the feeling "of less WiFi range", because devices that are further away seem to 
have trouble connecting at 1st try. For me, standing at the exact same 
distance, I've observed my devices connecting fine.
It's a "mysterious" story since then, because I've read a lot of threads here 
(and participated myself), I feel like 80% of the feedback I got for my "ath10 
non-ct builds" was "hey, my WiFi problems with the Archver C7's were solved 
thank you." and the rest like "not sure - or it's the same like with ct 
drivers".

This leads me to kindly ask you to consider including ath10k (non-ct) drivers 
in the next upcoming major OpenWrt releases. It would save me and other people 
the effort to build a new OpenWrt image ourselves whenever a new official 
stable commit is available as release. I'd hope to use the official built 
images again in the future and also advise other people to use them. You are 
really doing great work on OpenWrt!

Thank you.

Kind regards
