Limited Access After 8.1 upgrade

I have an ASUS K35TK, it's about a year old, and was running windows 7, until I upgraded to 8.1 about 5 days ago. Since upgrade I frequently get limited access. I've never had this problem before upgrading. While it's limited on my asus, my parents laptops still work, my iPod, tablet and other devices. The network checks fine. The only thing different is my OS. I've tried disabling IPV6, as suggested for this problem, I got nothing. I've deleted my profile and reconnected, I've done some stuff with netsh commands on CMD, and nothing changes. Connecting through Ethernet is fine, just the wireless is messed up. I downloaded all the proper drivers for windows 8 from the asus website before upgrading. Everything installed fine and I'm not having any driver issues. This is an error specifically with windows 8.1. My brother had run 8 for a we months with everything fine, he upgraded to 8.1 and has the same problem. He has a Lenova with completely different specs. But I'm at a loss, and it's frustrated me so intensely. Apparently it's a common issue, and I haven't found anything to fix it. SO please, if you can help, let me know.

Hmmm are you sure that isn't the Asus K53TK?

The problem isn't with Windows 8.1 specifically, the problem is that Asus has not updated the wireless drivers for your ASUS K53TK, which only shows drivers for Windows 8 but not 8.1.

You should keep checking the Asus site or Windows update for an updated driver.

Yes ! That's right, I'm sorry, I didn't pull the right name out of the top of my head. But yes, it's the K53TK. And it says all drivers are updated, but that would make sense if it hasn't gotten an 8.1 release for my driver. But yea, I checked the asus site 4 days ago, and downloaded all the right windows 8 drivers before upgrading just in case. But I guess I'll just have to wait am for asus to update. Thanks for the reply !
