Causes of Samsung TV Disconnecting from WiFi

Interference- Wireless signals can easily get interrupted by various interference. Things like thick walls, large appliances, and crowded wireless networks can all degrade your WiFi signal quality. If your WiFi router is far away or there are a lot of objects between it and your TV, it may struggle to maintain a steady connection.

Outdated software- Samsung routinely rolls out software updates for their TVs like other smart devices. If your TV is not running the latest firmware, it may have bugs or connection issues that are fixed in newer versions. Failing to keep your system software up-to-date could be the reason for random disconnections.

Overloaded network- If you have many devices simultaneously connecting to your home WiFi network, they can overload the router and cause connectivity problems. Too many high-bandwidth streams or downloads at once can temporarily disrupt the wireless signal between the router and your TV.

Weak password- If your WiFi password is outdated or easy to crack, others may access your network without your knowledge. This strains the available bandwidth and can cause the TV to disconnect frequently. Using a strong, unique password can help prevent unauthorized usage of your network.

Power level setting- Some WiFi routers allow adjusting the strength of the wireless signal broadcast. If this is set too low, your TV may struggle to maintain a consistent connection. Check that the power level is at 70-100% for best results.

Frequency interference- WiFi’s 2.4GHz and 5GHz frequency bands can encounter interference from other devices like baby monitors, cordless phones, microwaves, and Bluetooth gadgets. If these are too close to your router or TV, they may disrupt the signal.

Faulty hardware- In rare cases, the TV’s WiFi antenna or wireless card could be defective. If you’ve ruled out the other issues, this physical hardware problem may require repair or replacement.

Samsung TV Keeps Disconnecting from WiFi: Troubleshooting Steps

Before calling for professional help, there are a few basic troubleshooting tips you can attempt yourself to get your Samsung TV connecting reliably again:

Restart your devices

Simply turning your TV and router off and back on again can clear up temporary glitches and get the WiFi working again. Unplug both for one minute before restarting. Also, restart your cable/DSL modem if applicable.

Check proximity to the router

Samsung recommends placing your TV within 15 feet of your WiFi router for optimal connectivity. Walls and interference will further limit this range. Move the devices closer together if possible, or look into WiFi extenders.

Remove obstacles

Check for objects that may be blocking the signal path between your TV and router. Thick walls, cabinets, appliances, and electronics can degrade WiFi strength. Change the orientation or clear any obstructions.

Update software

Search your TV settings menu for firmware updates. Apply the latest software update to rule out bugs in older versions. Also, update your streaming devices, smart home hubs, and router firmware.

Change WiFi channel

Log into your router admin page and try changing the broadcast channel to a clearer one. Nearby networks may cause interference if using the same channel. Channels 1, 6, or 11 are typically best.

Adjust router position

Elevating your WiFi router and positioning the antennas vertically can significantly improve signal range and strength. Place it in a central area on an upper floor or shelf for best coverage.

Check router settings

Ensure the security, encryption type, and password are current on your network settings. Disable any unused ethernet ports or features like guest networks that could impact connection speeds.

Replace router

If your router is several years old, replacing it with a newer model with stronger WiFi capability may be necessary. Dual-band routers on the 5GHz frequency are ideal for streaming 4K video.

Add WiFi extender

For very large homes, you may need a mesh WiFi system or an extender to boost coverage in the area around your TV. This pulls the signal from the router and rebroadcasts it locally.

Try wired connection

For the most reliable connectivity, use an ethernet cable to connect your Samsung TV directly to your home router or modem if possible. This removes WiFi as a point of failure.

Reset network setting

As a last resort, reset your TV network settings to factory defaults. Open Settings > General > Reset and choose “Reset network settings”. Be aware you’ll have to set up WiFi again afterward.

If you are still experiencing frequent disconnections after trying these tips, your Samsung TV, router, or WiFi environment may have underlying issues requiring professional service. Contact Samsung Support or your local TV repair shop for additional help diagnosing and resolving persistent wireless connectivity problems. Investing in robust home networking equipment and setup can provide more consistent streaming to your Samsung Smart TV.
