I had one room where I couldn't get wifi and bought a TP-Link wireless extender that is working will with the BT hub. BT also do them but they are much more expensive. Many other makes on the market.
Yep, but they are not helpful if you need a long range link with special antennae or anything, or, as in my current case, it needs to be a different network. Fine just to fill in a dead spot in the house though (not withstanding the loss of bandwidth if it is of the wifi rebroadcasting type, and if it is of the powerline type then all of the previous discussion applies). A mesh network may be a better solution and they are becoming more widely available now as just mentioned.
