Public bug reported:
ISO testing 20.04 Lubuntu daily (20200315). From the Live desktop, I
click my nm-tray access point, supply the password. nm-tray will
timeout. Trying again will timeout. What works is clicking the same
access point a couple times before it times out. This causes an
immediate failure and successful connection (two balloon msgs).
This problem is not specific to Lubuntu. It happens with Kubuntu,
Budgie, Mate, Xubuntu. The common theme is: it appears to be out of sync
in some manner. The wifi connection needs to be interrupted before
timing out. Then an immediate attempt (within 2-3 seconds? I haven't
tested how long it can wait) succeeds.
This problem also happens after install and reboot. For example, with
yesterday's daily image (20200314), I had to reboot Lubuntu twice after
install before the wifi worked. (I haven't reached that point yet today.
I'm creating this bug report from the Live desktop. I will update with
more info about post-install.).
Note: I don't know if this is acceptable wifi behavior. Good enough? I
figured I should report it and let someone decide. It seems to be
specific to this laptop (Lenovo Thinkpad E440 20C5) or it's Intel 7260
wifi card.
