Make sure you are using only channels 1, 6 or 11.
It could be that the room the router is located in has a wall that has chicken wire inside it
As a good test, do you have a smartphone such as an iPhone?
If so, turn on the personal hotspot setting, stay on this screen (do not go off this screen - changing screens stops it working correctly), this now makes your router into a wifi Hotspot.
Place the iPhone next to the router... do your devices see the signal as weak as the original router?
An iPhone should give off a much weaker signal than the router, so it should by rights be much weaker. If it's the same / better then you know the routers pretty junk. EDIT: The WiFi is so bad that turning my homehub on next to this router, would mean I couldn't even connect to the technicolour WiFi as my homehub literally overpowered it that much on the same channel. Having both a sky hub and homehub on same channel next to one another - worked fine on both. I assume it's because the Sky hub is a fairly strong range as well. So it's possible neighbours devices with a much stronger WiFi output aren't helping as they're overpowering the measly signal.
Also is your router one of these? http://ecx.images-amazon.com/images/I/71UgdlsyEqL._S...
If so they have terrible WiFi range. Well compared to the homehub I have it's truly abysmal...
