2019 4K Toshiba Fire TV problems galore?
 

It keeps losing the wifi feed.

Its last year's model and is 42 in.

Hopefully the model number won't be necessary because I have poor eyesight .

The router is about 20 feet away.

I have a similar sized Samsung TV more than 50 feet away and has no trouble receiving wifi feed.

Thinking about getting another Samsung TV (as a replacement) and just add an Amazon Fire TV device.

If the above Toshiba TV has memory problems what's the best way to delete useless apps to free up space?

I could run a line from the router to the TV too see if that helps and if that does work then I would need to move the TV closer to the router.
