I allow myself to ask for your help. I am completely new to openwrt. I managed to flash my router without any problem, OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.272.48698-9883bb3.
I am having wifi cutoff problems on all my peripherals, 2.4GHz and 5Hz. Often on peripherals the wifi logo with the exclamation point appears to say that there is no internet connection, or when I stream music the sound cuts off at times. The videos on the chromecast freeze waiting to load.
In short, as it is, it is not 100% functional.
The 2.4GHz driver displays GENERIC and the noise level on the 2 wifi bands displays unavailable.
I hesitate to go back to stock firmware but the openwrt features are great and I would miss it.
Thank you for your help
