Television recommendations please

Here is why I think it may be my wifi extender. I can spend a good half hour doing soft and hard reboots of my tv in the bedroom and get nothing. I can disconnect it, bring it into the living room and it connects immediately after being plugged in. The wifi extender is about 20 ft from the tv, with only the bedroom door in the way, and even with the door open, it won't connect. My laptop and phone connect fine from the bedroom, but they connect just fine even when I bypass the extender and connect to the main hub.
