Public bug reported:
Hallo,
since an update of my xubuntu 18.04.2 the onboard Wlan connection to the
Internet is not working properly.
If my Notebook is close to the Wlan Access Point, i can't get an Internet
access, no Websit, no Ping is anserewd, the wlan Icon shows full strength and
IP is assigned. When I go with my Notebook 2 rooms further everything works.
Then I go back the same Issue. With an USB Wifi Dongle it works evrything
properly, so it is not a Network Problem. With a Live DVD and an Older kernel
the onboard Wlan HW works properly, so it is also not a Hardware Problem.
The only diffrence between the two conditions is the antenna Position in the
room and the Signal strength see below.
