I have the R7800 which I flashed Kongs latest openwrt build with stock settings, everythings seems to work great except one thing.
I have the LG OLED C8 TV, it won't stay connected to the 5GHz WiFi, I can connect to it but after a few seconds or minutes it disconnects, it works good with 2.4GHz but I get low speeds so can't use it, every other devices works without problem.
I noticed that I can't choose auto when choosing the width (20/40/80/160MHz) so I use 80MHz which I've done before, but when using 20MHz the TV seems to stay connected but I get lower speeds so can't use it either, maybe if it was possible to have a auto option it could work, but the 80MHz settings works with Voxel firmware and the ASUS RT-AC86U with Merlin firmware.
I think it's something with openwrt but its funny because every other devices works great, maybe there is a setting I should change? or maybe try another openwrt build that maybe works better? thank you!
