Over the last couple of days I have been having issues with 3 samsung devices connecting via wifi on a hub 3. The devices are a a20 mobile, j6 mobile and a samsung tablet. The strange thing is that another samsung tablet in the house is connected perfectly with no issues. TV and streaming from tv is connected fine. All 3 devices are saying incorrect IP address. I've tried various resetting etc on both device and router to no avail. The virgin tv and wifi service was down in the area on thursday last week. It came back on but with a flashing green wifi light on the router. The devices were connected but when i restarted the router to try and get rid of the flashing light I've never been able to get the devices to reconnect. I really dont know if this is a router issue or samsung issue? Could it be something to do with a recent Android update possibly? Any help will be greatly appreciated.
