No Wifi Post-install Possible Fix


Post by j2mcgreg » Mon Jan 14, 2019 3:51 pm

I have been doing some research on why wifi failed in my latest attempt to install MX18 on this Acer Aspire 3. I searched "no wifi post-install" on google which first took me to a Win 10 forum and that led me to an Acer and then Lenovo forum. Apparently, on newer Acers and Lenovos that use the InsydeH20 Set-up Utility, there is a glitch that causes Gnome to activate Airplane Mode during the install. I then searched for 'Airplane Mode Debian Stretch' which led me to this page from the Debian forums :


The gist of which is:
First, as root, run:

Code: Select all

rfkill list all
then, if it shows that wireless is software blocked, as root run:

Code: Select all

rfkill unblock all
followed by:

Code: Select all

ifup wlan0
Note that it appears that setup utilities other than InsydeH2O provide the utility to disable Air Plane mode. There was talk in the lenovo forums on how to disable Air Plane mode by disabling a module in the bios.

I haven't tried this yet, but will tonight or tomorrow morning.

reminds me of my old EEEPC904ha. when you flip the wifi off under windows, it actually changed a bios switch that survived reboots into linux. took a while to find that one.
lenovo ThinkPad T530 - MX-18
lenovo s21e - MX-18, antiX-17.3.1 (live-USB)
FYI: mx "test" repo is not the same thing as debian testing repo.
