I have a Lenovo thinkpad 13 laptop running Linux mint 18. After a recent update it stopped logging in to my university network (still worked at home). Someone suggested that I remove network manager from my system and try wicd. But when I did that and rebooted, there is a problem with xsession and it keeps saying "your session lasted less than 10 seconds...etc"
This has happened before on my old laptop when doing something else and the solution was to just type:
sudo apt-get install cinnamon
However, my problem now is that I have no internet connection so I cannot reinstall cinnamon. My laptop has no dedicated ethernet port so I can't plug directly to the router, however I have been able to usb tether from my phone in the past.
Is there a way of connecting via my USB phone tethering so that I can reinstall cinnamon and log back in to mint? Or failing that, is there a way I can install the cinnamon package from a USB drive?
I think my wifi might still be available too. When I type iwconfig, the result is:
