Like many, I've been eagerly awaiting the 8.1 upgrade for my Pro. Not because it wasn't working well (it was working VERY well) but because so many of the new features are so great. So Friday morning I updated to 8.1 and it has been SO frustrating so far. The new tiles sizes and customizations and new features are fantastic. I REALLY like 8.1s design. But my Pro can't seem hold a WiFi signal for more than about 3 minutes. Even when I do manage to get connected, its weak. It takes ages to load anything online. On Windows 8 browsing was like lightning. I'm so frustrated with it. Also, not 5 minutes ago, I attached my Type Cover, and the Surface randomly rebooted. I tried a Refresh, it helped a little. But right now this is borderline unusable. I guess I could roll back to 8, but that would be really disappointing. Anyone else having similar issues? Can anyone help me out?
