You can actually try other channels, but I will say that the best solution is to place your wireless router in a central point. Otherwise, the PLC can be a very good alternative, except that I do not know the speed allowed.

It will probably, on the interface configuration. wireless router explore the performance of each channel from 1 to 13, rebooted the router once , one of them will provide you the best connection.
