Over the last several weeks, my Surface Pro 3 has ceased to work on the network I used to do my remote work. But my other devices connect just finely. You load the page, it tests for antivirus, and once it finds it, it goes to a page that says "Continue to Internet." My Surface no longer does it. I tried restoring my service to a previous date, and then Windows would not load. I ultimately had to run a recovery just to get back into Windows. Now I notice my Surface takes longer to connect to other networks and may well allow only a limited connection. I got it to connect to my phone, which eats up my data, but it's going slower. I can't figure this out.
