Just installed Ubuntu 18.04.3 LTS, but my Wifi connection is terrible, barely getting into any website. I have a Qualcomm QCA9565 802.11b/g/n Wirelles adapter, with all the drivers on OS updated. Did I miss something? Some driver? Do I need to install something else, or activate it?

Thanks for the time!

    Is this a USB wireless adapter? – Some Guy With Cats Sep 9 at 18:02
  • willhaley.com/blog/finding-linux-wifi-usb sheds some light on the subject, confirmed by itsfoss.community/t/… – K7AAY Sep 9 at 20:39
  • @Caio Varella Bento 802.11b and 802.11g use the 2.4GHz channels which can be slow since so many others also use them; 802.11n uses 2.4GHz or 5GHz which is often much better. Please click edit to tell us which channel you use askubuntu.com/questions/309458/… & also advise whether your WiFi adapter is USB-attached, or inside the PC. If it's inside a laptop, please provide the make & model # as well; please get the model # off the sticker which also has the serial #. – K7AAY Sep 9 at 23:10
