1) Along with the "system freezing" problem I have been having with 5.4, I also sometimes can't connect to the wifi I have been using for years. I have a modem in the room next to my office and I also have a hot spot on my desk, and sometimes LL will simply not connect to them.
(and occasionally LL will connect to the modem but still will not work)
2) Also - I have a TP-Link TL-WN725N usb adapter, and I don't think LL recognizes it.
This is a dual boot system, and Windows still connects to both easily and they both work well.
suggestions?
