Cannot maintain tv connections. Speeds not good

I upgraded to Gigoblast with Panoramic Gateway about a month ago.  Since that time, I have had nothing but problems.  My televisions are all smart tvs and I must reconnect them daily.  Also, I have not gotten speeds above 240 mbps.  Honestly, my previous service was much  better for less money.  I've tried all of the recommended solutions, but have seen no improvement.
