Lotsa different things going on here.

You guys have heard me say it before, don't buy Smart TV's if you have a dumb option because of crap like this.

Separate your points of failure.

We all agree by now that WIFI is for convenience and wired is for performance.

WIFI, at best, will only deliver ~half the bandwidth you are contracted for.

This happens because WIFI does not have backhaul. (Mostly but we will get to that)

Think of WIFI as an old school bucket fire brigade with a line of fireman passing buckets but they only have one bucket.

They pass a full bucket forward but have to pass the empty back down the same line before they can pass another full one forward.

If you had two lines of fireman and more buckets, one line passing buckets forward and the other passing empty buckets back you can dump a **** ton more water.

The line passing empty buckets back is backhaul.

There are ways to address it using Mesh systems where one AP can broadcast and another provide backhaul or a hidden 2nd 2.4ghz band dedicated to it.

Some router vendors use the combined SSID trick where they broadcast on 5 and receive backhaul on 2.4. I've never been a fan of that as I've not seen it work consistently.

For TV's really the best solution is a MoCA to ethernet bridge. Generally cable drops are in or near areas where people would naturally put a TV. Your broadband service runs on MoCA which means it's passing ethernet over coax. Unless your coax network is old and janky it's the best solution as coax is capable of gigabit.

Even if there is a coax drop closer to the TV than any AP's or router it's a better solution as it allows you to hardwire an AP closer to the TV.
