Hi, I have similar issue with AC3165 on Lenovo 720S. To be more precise I can't connect to 2.4Ghz network on new TP-Link router but able to connect to 5Ghz network. Insteresting that the issue doesn't not appear with older access point which provides only 2.4Ghz network using the same WiFi basic settings (802.11n mode, 20Mhz channel bandwith, AES encryption).
*BUT* what does solve the issue in my case is reloading of iwlwifi module after boot. I.e. doing # modprobe -r iwlwifi # modprobe iwlwifi fixes 2.4Ghz connection issue with TP-Link -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1848953 Title: Intel wifi 3165 [8086:3165] subsystem id [8086:4010] not working properly in Ubuntu 19.10 Status in linux package in Ubuntu: Confirmed Bug description: I have a clean install of the latest Ubuntu, 19.10, but since the live usb, a bug appeared.
