Looking for Adapter or Router or Access Point

[G_Pap]

Hello, I have WNCE 4004 connected to an IPTV device and I don't have good picture quality ( I have played with the settings ). 

This adapter can run only at 450 Mbps - 5GHz as I see in the specs.

I read somewhere that in case my IPTV device works fine it needs to be connected with Gigabit Router via cable.

Because I cannot do that ( different rooms ), is there any similar adapter that offers Gigabit via Ethernet ?

Maybe a Router or Access Point can help, please suggest me.

Thanks.
