Hi, wifi is not the T8s strength, check the reviews. As for 5g I was the same when I got mine, and on 2g I was only getting 8mbs. So I'm wired now and getting 12 to 14, witch for full HD and 5.1 is fine. Have you tried changing channels on your router, that may help...but the way I look at it is as long as it does not effect your viewing pleasure, does it matter. Enjoy and a Happy Easter to you to.
