Several Devices Connected: 

Many home devices are connected to the same network, like laptops, phones, TVs, and smart home devices. Meanwhile, connecting too many devices to the same network system may result in some connectivity issues. For instance, connecting too many devices to the same network results in a slow Wi-Fi network, which eventually causes the TV not to connect to the Wi-Fi network.

Incorrect Date/Time

All the LG TVs have a built-in internet time, which is used to keep track of time. Your network may be out of sync with the date and time.

Generic Bug

Sometimes, you may feel that your TV is experiencing a temporary error or problem with the Smart functions. You may see an error code on your device, and the apps may stop working. If this happens, please wait a few hours to see if the issue goes away.

Old Firmware

Updating your TV’s firmware will repair bugs, cover security holes, develop the TV’s performance, and improve its compatibility with other devices.

Weak and disturbed Signal

If your router and TV are far apart, you will have a rough time connecting it with the router. So, you’ll need an adapter like power over ethernet or network over coax to keep your link as firm as possible.

Location Settings of the LG TV

LG TV might face Wi-Fi connectivity issues if an incompatibility issue is seen in the location settings. The difference in the location of the tv and router may result in this problem.

Quick Start of the LG TV

Many recent gadgets, including LG TV, use a Quick Start feature to decrease the device’s boot time, but sometimes, this feature fails to load essential device firmware modules (including Wi-Fi), thus causing the issue at hand.

Auto Optimize Network Settings of your Router

If your router is configured to auto-optimize the network, it leads to various issues under discussion. The TV’s data packets by this auto-optimize function of the router may bring problems in the compatibility between the TV and router.

Corrupt Firmware of the  TV and Router

If the router’s or firmware is corrupt, it roots in one’s incompatibility with the other and causes Wi-Fi connection problems.

LG TVs mostly have difficulties connecting to Wi-Fi because of signal strength or router compatibility issues. You can solve most problems by resetting the TV’s settings and the security setting on your router.
