Hello,
Today I installed the updates and, in addition to several packages, the
wireless-regdb:amd64 (2018.05.09-0ubuntu1~18.04.1, 2020.11.20-0ubuntu1~18.04.1)
has been updated too. As a result, my previous connection problem has been
fixed.
** Changed in: linux (Ubuntu)
Status:
Dear You-Sheng Yang,
I installed the i915 firmware, unfortunately it had no effect on WIFI.
(I read that this is required for the graphics card.)
How can I set the kernel-bug-existence-upstream tag in your comment
above?
