Be sure to talk to the laptop maker about drivers for 8.1. Some laptops are not ready.
I updated my laptop from Windows 8 to Windows 8.1 about 3 weeks ago and since than I have problems with Google Chrome and internet connection.
My Google chrome randomly freezes, specially if I have more than 1 tab opened. I also have to refresh the web page multiple times before it's completly loaded. Another problem is that Google chrome seems to have issue with flash player. I have tryed many thing already and non of them fixed the problem. One of the things that I tryed was that I disabeled pepflashplayer in plugins.
I also have a problem with internet connection 2-3x a day I use connection with my wi-fi, than it needs 10 minutes to connect back on, after this most of the websites don't wotk for another hour or so.
I noticed that many Windows 8.1 users have similar problems but I couldn't find the solution.
