So I just got my N5 and now I'm having problems with data. Whenever I try to go to a website, it would just direct me to tmobile's login website and a sign into network notification pops up as well. When I log in, the website doesn't even load. I've tried changing APNs, network mode, custom roms and several solutions over the internet but nothing works. I have a grandfathered data plan so that might be the problem but it works fine on my Galaxy Nexus. I'm taking it to the store tomorrow but if anyone can suggest a solution it'd be great.
