I've always been able to connect my laptop in the garden which is about 40 meters from the H633 router, but just lately the WiFi just doesn't seem to reach? It's the same with my phone, I used to get full WiFi, but now my phone connects to it's own 4G? It's now even getting really hard to connect in the kitchen, it's as though the power is slowly reducing? The router has not been moved and is in the same place its always been. Has anybody had this problem? Or is the routers WiFi on it's way out? Any help would be gratefully appreciated.
