Slow Internet Streaming

[Waynejwj]

I have had a Hisense 75U7K for a month now but it has an annoying problem. The first two weeks it functioned fine. I use this TV for internet streaming about 75% of the time and after about a week the Tv slows down dramatically when switching between streaming services and anything internet related. It gets so slow that it will eventually take several minutes to perform any web activity. The TV channels work properly. Now about once a week I have to unplug the TV and restart in order to get the Tv to function normally. Once I restart the TV switches very quickly. I have tried several suggestions on the internet including clearing the cache. I owned a Hisense 75U7G for 20 months until the panel went bad. The 75U7G did not have this problem. I have 75 Meg wifi connection on 5g for two TV's.
