I am having a similar issue. Got the phone on Friday and had to connect to wifi every 2 minutes during the restore. Watching a video for 10 minutes, I had to reconnect to wifi atleast 5-6 times. Seems to be a widely known issue with iphone 5. I have a call with their support tomorrow. Will update what they say.

They recommended resetting it to factory settings and then restoring from back up. It didn't work for me so they got my phone replaced recently. Haven't had issues on my new phone so far.
