I am at wits' end. I've been at it for 14 hours now.
It was actually working fine before a windows 8.1 update came along. I don't know what Microsoft did, but my once happy laptop experience became a nightmare.
Now I need to get close to the router just so I could have a stable connection.
This is just absolutely frustrating since I use my laptop for gaming.Prior to the update, I could play online games just fine on my table. Now I can't even get past my the character select screen. It's definitely the wireless card, because I have a portable router in the same location as my laptop, and everything works properly (connected via LAN cable).
I have literally tried everything that I can, but I just can't seem to make the 7260AC go back to the way it was. I've refreshed my laptop, restored it to factory settings (going back to windows 8 from 8.1), and practically done everything that all the users recommended in this site.
I just don't know what to do anymore. I have an Asus N550jk. The router I'm connected to is only 2.4Ghz, the encryption is TKIP/AES. It shouldn't really matter since it worked with the same settings before some windows 8.1 patch made it break.
I really just hope that Intel solves this soon. I have always liked Intel products. Now I'm not really sure.
