[Kernel-packages] [Bug 1569484] Re: Auto Ethernet connection profile appears. Wifi does not work anymore.
I've tried kernel 4.6rc3 to no avail (same machine, Dell XPS 13 9350). The thing has the broadcom 4350 card. I'm running a 4.4 lowlatency kernel on this machine, which is not upgraded automatically or anything, so the problem can IMHO not come from a kernel change, but it must be something network-manager (or external driver) related. The "error getting signal strenght" is only a consequence of the wifi not being recognized as a wifi, but as an ethernet connection. Ethernet doesn't have the parameter "signal strength". The problem lies here: GERÄTTYP STATUS VERBINDUNG docker0 bridgeverbundendocker0 wlp3s0 ethernet verbundenwlp3s0 wlp3s0 is found to be an ethernet connection. Since today also my MacBook Pro shows the same behaviour, with a broadcom BCM43602. I manage to get wifi running by defining the ssid/passphrase with wpa_passphrase, starting wpa_supplicant manually and then running dhclient on the interface and setting a nameserver in /etc/resolv.conf by hand. I ordered an Intel wifi card for now, want to see if this changes anything. Strange enough, every 26th (or something around that) will let the wifi show up like it's supposed to, so the problem is really very hard to grasp. -- 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/1569484 Title: Auto Ethernet connection profile appears.

Definitely seems to be brcm-driver related; I swapped my card for an intel 8260 and everything works like a charm. If any logs are needed I can provide from my macbook pro with the same issue. -- 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/1569484 Title: Auto Ethernet connection profile appears.

Regarding https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1990700/comments/13: I'm still seeing the same issue on Ubuntu 22.10 with mainline kernel 6.1.8 and 6.1.9.

About the 5G support: nm-applet reports LTE, but it does work on 5G. I just got 400+ Mbps yesterday when testing, which obviously is not LTE. Might just be a naming issue there.
