Sorry if this is dumb, I'm new to Ubuntu and just jumped in. My issue is the my WiFi will connect fine, but after a few minutes it will stop working, but still say it's connected fine. I can temporarily fix this by disconnecting and reconnecting, but it will occur again. I'm not sure if I need some sort of driver or software, so if anyone can answer or anything it's greatly appreciated.

  • Please edit your question and add output of lspci -knn | grep Net -A3 terminal command. This will give the information needed about your specific WiFi device. Also make sure to set the recommended wireless encryption settings, WPA2-AES, at your router. Avoid any WPA/WPA2 mixed mode and/or TKIP.

  • Possible duplicate of Wireless disconnect issues Ubuntu 16.04 with RTL8821ae Yes, your device need tweaks, the default driver installed by Ubuntu isn't the best.

    @MichaelBay the single antenna issue seems to be limited to HP laptops with RTL8723be chipsets
