This is my first day with the lumia 928. I previously had the 822 but was having too many problems with it. I am now having some of the SAME problems with this phone. I cannot use wifi. My phone will connect to the wifi, but will not let me use any apps that require internet and I cannot go on the internet period unless wifi is shut off and I use my data. I have tried rebooting it and resetting it and deleting and re-adding the wifi on my phone. The issue does NOT have to do with the wifi itself, my ipod, computer, and my friends devices all connect without problem. I cannot do anything with the router anyway, since I am at college and it is their wifi. I am very frustrated at this because I have had this issue with my 822 and it never seems to get fixed. I have already used all of my data for the plan. Any suggestions?
