Picked up the i5/256/8 model from BB yesterday. It simply will not stay connected to wifi, literally for more than a few seconds at a time. I've tried the registry edit that MS posted as a workaround for slow wifi connectivity, but that didn't help. I've even done a fresh reinstall of W10. No luck. Starting to think it's a hardware issue. Before I go trouble of boxing it up and exchanging it for a new model at BB, any other suggestions?
