I own a TP-Link Archer C7 V2. Using it with the original firmware was not very satisfying as it was constantly disconnecting WiFi connections. I installed LEDE 17.01.4 and this fixed the disconnection problem. I got good WiFi speeds: about 50 Mbps on 2.4 GHz and about 100 Mbps on the 5 GHz. The range was reasonable throughout the house. After a couple of years of trouble free use, the router started disconnecting frequently again, so I upgraded to OpenWRT using openwrt-19.07.3-ath79-generic-tplink_archer-c7-v2-squashfs-sysupgrade.bin
Upgrade went smoothly, and the wifi disconnection problem seemed to be fixed. Now I notice the WiFi range seems poorer and we only get about 50Mbps on the 5 GHz WiFi, even went the device is right next to the router. The 5Ghz WiFi is set AC Mode, auto Channel with Width set to 80GHz. Max transmit power set to driver default.
Any ideas on how to squeeze more speed and range out of the WiFi. I am wondering if this is a driver issue.
I initially upgraded from Firmware to LEDE-17.01.4 and then flashed OpenWRT from within the Backup/Fash Firmware menu, using openwrt-19.07.3-ath79-generic-tplink_archer-c7-v2-squashfs-sysupgrade.
This is what I get when I try to install
Package kmod-ath10k (4.14.180+4.19.120-1-1) installed in root is up to date.
Collected errors:
* opkg_install_cmd: Cannot install package kmod-ath10kath10k-firmware-qca988x.

I can easily bring back the ath10k-firmware-qca988x-ct kmod-ath10k-ct by reflashing sysupgrade file, but I'd like to get more functional WiFi drivers if I can.
I had a similar problem with my TP-Link Archer C7 and Openwrt 19.07.3. CatFriend1 instructions fixed it.
Mine was worse as 5 GHz would not even start without the recommended change in package.
Is there a bug report for this ?
