Title:
BCM43602 802.11ac Wireless regression - PCI ID 14e4:43ba
Status in linux package in Ubuntu:
Confirmed
Status in linux-signed package in Ubuntu:
New
Bug description:
[Description]
The wifi device BCM43602 802.11ac Wireless (PCI ID 14e4:43ba) running
with the proposed kernel 4.4.0-155.182-generic will cause kernel
trace[1]. However the wifi function works properly with the kernel
4.4.0-154.181
[Steps to Reproduce]
1. Install ubuntu xenial, enable the proposed repository, and update the
system with "sudo apt-get dist-upgrade"
2. nmcli d wifi rescan
3. nmcli -t -f SSID,CHAN,FREQ,SIGNAL d wifi list ifname wlp2s0 (if your wifi
interface is wlp2s0), you will see the available SSIDs in your environment.
4. nmcli d wifi connect <SSID> ifname wlp2s0 name TEST_CON
[Expected Result]
The AP is connected
[Actual Result]
You will get the message: "Error: Connection activation failed: (5) IP
configuration could not be reserved (no available address, timeout, etc.)." and
the kernel trace from /var/log/syslog[1]
Sometime the system hangs when connecting to a wifi AP.
