I had no issues with my Droid Razr Maxx dropping wifi connections before the update. I use my work's wifi connection (to which I have no access to the router or anything like that) and I will connect to it and accept the user agreement, and half an hour later I'll look at my phone and the wifi indicator will be grayed out and it's prompting me to accept the wifi user agreement again, meaning it is not connected. I never had this problem before the update. I haven't gone out of service range - I've been sitting at my desk. I've tried forgetting the connection and adding it again - no dice. I've seen on this forum that if you replace your router or reset it, that might work, but I have a feeling if I went to the IT guy and told him that I need him to reset the entire router for my phone, he would laugh and point.
Any ideas?
