If you want to speed up your TV’s performance and avoid lagging, then you should use an ethernet connection. 

Unlike the Wifi connection, ethernet provides reliable connectivity because of its low latency rate.

The wifi signals become slow due to the distractions like walls, roofs, fans, furniture, etc. That’s why these weak signals impact the performance of the TV. 

You need an ethernet cable to establish an ethernet or wired connection with your Vizio TV. Connect one end of that cable to the router and plug the other end into the ethernet port behind Vizio TV. 

Once you have connected the ethernet cable, check the internet speed on your TV, and you will never regret this.

4- Keep The Router Closer To TV

The rule of thumb is to closer the router from your TV the higher will be its internet speed. If you don’t want to install an ethernet connection, then make sure to keep the router close to Vizio TV. 

So before placing a router you should consider a few things; 

  • Elevate the router to improve signal strength. This usually helps you to avoid distractions like furniture. Plus, this prevents signals from being transmitted directly to the ground. 
  • Keep the router closer to your TV to avoid distractions. This prevents signals from losing strength due to distractions. 
  • Keep the wifi router far away from other electronic devices like microwaves.

5- Ask Your Internet Provider To Upgrade The Plan

If you’re connecting more devices with wifi network, it will gradually become slow. And this impact the internet performance across various defies, including your Vizio TV. 

So make sure to connect limited devices with your wifi router. Or if you don’t want to disconnect devices, ask your internet provider to upgrade the plan. 

Also, use a 5GHz band wifi network instead of 2.4GHz. The 5GHz band provides more stable, reliable, and faster intense performance in the shower range.
