connect wireless router to access point via powerline adapters
Have a wireless router in the basement and want to put an access point on the second floor. Don't want to run a cable so thought about using powerline adapters to connect the two. I can't find anything that states this will work
That is pretty much what powerline adapters are made for. They do work but be prepared to be disappointed with the throughput and buy them from a store with a good return policy. After the installation, check the throughput both a speed test web site and streaming video to a couple of devices to see if it bogs down too much. If you are satisfied with what they provide, then you are in good shape.
