In the past week (perhaps longer) my Note 5 loses Internet connectivity while on WiFi while other devices on the wifi network are fine. This has happened at home and work. The icon shows wifi is connected with a strong connection. Turning wifi on and off or toggling airplane mode don't fix the problem. If I restart the phone, however, connectivity will be restored. I've had the phone since it's release date and don't recall this being an issue before the last week or two. Anyone know how to fix or troubleshoot this?
