I had WIN8 and was happy with it. Microsoft updated me <without my permission BTW> to 8.1. I have had nothing but problems since!!! My computer won't stay connected to my ROUTER <I have to keep logging off and then back on if I'm IDLE too long>. My wireless printer is NOW NOT recognized by my puter and... My volume keys have suddenly stopped working. I purchased ad NEW router, thinking the router was the problem. I have rebooted router and printer <unplugging both> to no avail. I have tried updating the keyboard drivers and was told they are up to date. Any suggestions for all of my issues will be greatly appreciated. I'm about at my witts end. Hope someone can help.
