If the Wi-Fi signal on your TV device drops or intermittently disconnects, try a power restart or reset of your TV and your modem/router first. A power cycle or reset of your devices often improves or resolves Wi-Fi connectivity issues.
Restart the router. Unplug the power, wait about 1 minute, and reconnect. Try connecting another device to the router. If it works, it's a TV problem, and if it doesn't, it's a router problem.
Try connecting to a different network. Switch on hotspot on your phone, and then connect to that network via your Smart TV's network settings menu. If the Smart TV can access the Internet over other networks, the issue is likely to be in the router or Internet connection itself.
Your Wi-Fi connection could be cutting in and out, or dropping entirely due to a weak signal, distance from the router, interference from other devices, or outdated firmware. You can try moving closer to the router, reducing interference, updating firmware, or getting a Wi-Fi extender.
WiFi Dropping Out
There are a few factors that can cause issues with your WiFi signal. The distance from your router to your TV is important. If it's too far the signal will be weak and prone to dropping out. Move the position of the TV or the router closer to each other to avoid this.
Spyware and viruses can definitely cause problems, but your Internet connection speed can also be affected by add-on programs, the amount of memory the computer has, hard disk space and condition, and the programs that are running. Two of the most frequent causes of poor Internet performance are spyware and viruses.
Step One: Confirm Whether Your Internet Provider Is Down
If all your devices get no internet connection, yet your WiFi indicator is still on, the most obvious answer is that your internet provider has an outage. Before you start rebooting and shuffling wires around, it's always a good idea to check this first.
Restart your smart TV and Wi-Fi router
A restart will refresh the settings on your smart TV without erasing any of your data. Just unplug your smart TV, wait 30 seconds, then plug it back in. To restart your Wi-Fi router, unplug it, wait 30 seconds, then plug it back in too.
Select the Start button, then select Settings > Network & Internet > Status > Network reset.
If you use your Samsung TV to access the internet, you can also clear the cache in your TV's built-in browser. To do this, open the browser and go to the “Settings” menu. From there, you can select “Clear Browsing Data” and choose to clear the cache.
As a rule of thumb, a Netgear representative told us, consumers should consider replacing their router after three years, and representatives from Google and Linksys said a three-to-five-year window was appropriate. Amazon, which owns the popular Eero brand of routers, put the range at three to four years.
Most modems last for about 2-3 years but higher quality modems can last for 5-8 years. Most high quality modems end up being replaced because they become outdated, not because they have broken down.
The quickest, easiest, and most painless way to gauge your WiFi speed is to use a free, browser-based test like the one offered by Internet metrics company OOKLA at Speedtest.net. With about 8 billion tests under its belt, OOKLA has more data to back speed comparisons than any other tester out there.
It might be because of an outdated router or a less-than-ideal router location. You might be able to solve slow speeds with an easy fix, like upgrading to a mesh network (which also has to be set up in the right spot) or simply restarting your modem and router.
Why does LG TV Keep Losing WiFi Connection? There are a variety of reasons why LG TV remains disconnected from WiFi. Common causes include weak signals, out-of-current firmware, inaccurate date and/or time, WiFi connection-blocking features, and use of the 5GHz spectrum.
Restart your device.
Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference. If not, turn mobile data off and Wi-Fi on and check again.
