I'm having the same issue, it seems. Ever since I got the latest update, I can't access my Internet Browser, and because of that, I can't accept my wifi hotspot's terms and conditions, so I can't access wifi anymore until this gets resolved. It's getting irritating because when I found I had the issue, I had so much I wanted to do online, and now... nothing. Can't even add Friends, and my Fantasy Life game now gets heavy lag at times with my wireless switch on because it recognizes I'm in my wifI spot, and it's trying desparately to connect and failing, repeatedly.
If this doesn't get fixed soon, I won't be able to claim Diancie on my birthday this weekend in ORAS. D:
