Before you do any of this do a backup just in case: LuCI->system->backup
By deleting the ath10k-ct drivers under the "installed" menu, and then installing the non CT ath10k drivers from the "available" menu.
-
LuCI->system->software->update lists->installed->ath10k-firmware-qca9888-ct->remove->dismiss
-
filter->ath10k-firmware-qca9888->install->dismiss
-
Do the same thing with kmod-ath10k-ct, and install the non CT version.
