Why cant my Blu Ray player get a signal from my router?

I have a Samsung Blu-Ray player that is hooked up to Linksys Cisco Gaming adapter. I have this problem often where the Adapter(Living Room) will not pick up signal from my Linksys Router(Bedroom). Sometimes it works and sometimes it doesnt. So I am unable to watch Netflix. Are these two not compatible? Do I need a specific router/ adapter? Someone please help!
