I installed a lubuntu 16.04 and connected to my home network during install but have not been able to successfully connect after installing on my american megeatrends computer since. I connect to the internet without problems using my cell phone hotspot.

I'm using a belkin wireless usb adapter to connect to the internet. It worked fine when installing from usb. Once I installed the OS to the computer I could see my home network but could not connect to it. It would ask for the password, I entered it, and it would ask again, and again, never connecting. If I use my cell phone as a hot spot I connect instantly. I've spent more than an hour on the phone with my ISP, they don't think it's them, neither do I. I'm using the same adapter on another computer also running lubuntu and it works fine. I don't know if it's related but I can't shutdown my computer without pressing the power button. I've tried to power off from the terminal, I've tried adding acpi=force to /etc/default/grub among numerous other recommendations I've found online. Nothing works.
