Same problem here with my husband's Acer Netbook.
Everything's perfectly fine on my Laptop. Very weird. I hope they issue a fix for it soon as there seem to be quite a few people with the same problem.
I've tried all the "fixes" I could find on Google but none actually fixed it.
(this also seems to have been a problem in the beta)
hi,
I have done up gradation on 18th, And checked all points is ok.
I m using windows 8 Pro, If you have any problem wireless, check the system maintenance option and do the diagnostics.
If you have other problem with Windows Pro 8.1 , Please wright on the wall.
I've done all diagnostics, tried all fixes I could find online. Nothing solved the problem.
Ended up installing Windows 7 again and then upgraded back to Windows 8.
Will just stay away from 8.1 with the netbook.
Yeah I also had issues connecting to my wifi after the 8.1 update on my Vaio pro 13. A couple of restarts and repeated attempts of disconnecting and reconnecting to my network, it finally went through. It's working fine now but I noticed I have an update for my wireless in windows update. Not sure I'll install it in case it breaks it again.
