Is there a known issue with tv and blu-ray wifi adapters? I have a brand new sharp tv and panasonic blu-ray player in a room that is about 40' away from the wifi router, which itself is in it's own room. Other devices near the tv and blu ray player connect fine, like laptops and smartphones, although with a weak signal, but neither the tv or blu-ray connect. Both will intermittently detect the router but neither will connect. The blu-ray has updated firmware. Both items were bought at Costco so that may be part of the problem too....confirming my theory that Costco electronics are potentially inferior because of the price demands they put upon manufacturers. The wifi router is an Xfinity modem that is less than 6 months old.
I'm headed to Best Buy in the morning to look into buying a 3rd party wifi router, but I thought I would check in here first before I talk to one of their "geniuses".
