Please can you help. We have a wireless D-Link N router in the lounge but are not able to get a signal in our computer room. Do we need to buy an additional N router or relay to help boost the connection?
Try raising the router above furniture level.
Experiment with channels -- some work better than others in different environs.
If you can detect strong neighbouring wifi, choose a channel 5 stops from strongest neighbour.
Relocate cordless phone base, video sender away from router or computer.
Try moving the computer within the room.
