I woudl recomend doing a site survery of you house/office by:

Downloading http://www.metageek.net/products/inssider/

Then turn it on and walk around to all rooms to get a good idea of the other wifi interference in the area.

Now go into the router config and under wifi setting find channel.
Now based on you site survey pick a channel that is used little or empty keeping in mind the overlap as seen in the graph. 1 or 11 general work well because most users keep it on default 6.

In addition you need to check to see if the router is over heating. IT needs relatively good air flow to work correctly also do not stack another device below or above it because the extra heat will become a issues. If it has been overheated before that may be the issue and it may be permanently damaged.

Also keep in mind wifi will not go though steel or water very well so that may be contributing. In additon 2.4ghz wireless phones and microwaves cause problems. Changing the phone out with a 5.8ghz one will help and moving the router away from microwave will also help.
