I’ve got Realtek RTL8822BE 802.11q/b/g/n/ac WiFi adapter, rte_8822be driver on my laptop. Sometimes wifi just turns off saying ‘disconnected’, while inxi -N still shows both ethernet and wifi drivers present. Other times wifi adapter just straight-up disappears. Sometimes a few resets fix the problem.
