Samsung TVs fail to connect to WiFi most often because of distance from the router, interference from other devices, outdated software, or incorrect password entry

The first thing to check is whether your TV can actually see your network. Go to Settings > General > Network > Open Network Settings. If your WiFi network does not appear in the list of available networks, your TV is too far from the router or something is blocking the signal. Move the router closer, remove obstacles like metal filing cabinets or microwaves between the TV and router, or switch to a 2.4 GHz band if your router broadcasts both 2.4 GHz and 5 GHz — older Samsung TVs sometimes struggle with 5 GHz.

If your network appears but the TV will not connect, the most common cause is a typo in your WiFi password. Samsung's on-screen keyboard is small and straightforward to mistype on. Go back to Network Settings, select your network again, and re-enter the password character by character. If you are not sure what your password is, check the sticker on the back of your router or log into your router's admin page from a computer or phone.

If the password is correct and the TV still will not connect, restart both devices. Unplug the router for 30 seconds, plug it back in, and wait for it to fully boot. Then restart the TV by holding the power button on the remote for 10 seconds. This clears temporary connection errors that prevent the handshake between devices.

Key Takeaways

  • Check that your WiFi network appears in the available networks list — if it does not, move the router closer or remove obstacles like microwaves between the TV and router.
  • Re-enter your WiFi password character by character, because the on-screen keyboard makes typos straightforward and Samsung TVs will not tell you the password is wrong.
  • Restart both the router and the TV if the password is correct but the connection still fails.
  • Update your TV's software through Settings > Support > Software Update, because older firmware sometimes has WiFi bugs that newer versions fix.
  • If nothing works, forget the network on the TV and reconnect from scratch, which forces the TV to re-authenticate instead of using a corrupted saved connection.

Update your TV's software to fix WiFi bugs

Samsung releases software updates that patch WiFi connection problems. Go to Settings > Support > Software Update > Update Now. The TV will check for updates and install them if available. This process can take 10 to 15 minutes and the TV will restart on its own when finished.

If the update fails or hangs, it usually means the TV lost its internet connection during the read. Restart the TV and try again, or use a wired ethernet connection if your TV has an ethernet port. Some Samsung models have a USB port that accepts firmware updates from a flash drive — check your manual if the standard update method keeps failing.

Forget the network and reconnect from scratch

Sometimes the TV stores a corrupted version of your network settings and will not connect even though everything else is correct. Forgetting the network forces the TV to treat it as new and re-authenticate properly. Go to Settings > General > Network > Open Network Settings, select your network, and choose Forget. Wait 10 seconds, then select the network again and enter your password.

This step fixes connection loops where the TV connects briefly, disconnects, and tries again repeatedly. It also clears any saved settings that conflict with your current router configuration.

Check for interference from other devices

WiFi operates on radio frequencies that other household devices also use. Microwaves, cordless phones, baby monitors, and wireless speakers can all interfere with your TV's connection, especially on the 2.4 GHz band. If your router broadcasts both bands, switch your TV to 5 GHz in Network Settings — it has less interference but shorter range.

If you cannot switch bands or your TV does not support 5 GHz, move the router away from these devices or turn them off while you troubleshoot. Once you confirm the TV connects without interference, you can move the router back and accept occasional dropouts, or keep the devices separated.

Use a wired connection if WiFi keeps failing

If your Samsung TV has an ethernet port on the back, connect it directly to your router with an ethernet cable. This eliminates all WiFi problems and gives you a stable, faster connection. Go to Settings > General > Network > Open Network Settings and the TV should detect the wired connection automatically.

Wired connections are more reliable for streaming 4K video and downloading large software updates. If your router is far from the TV, you can run ethernet through walls using conduit or fish tape, or use a powerline adapter that sends the signal through your electrical wiring.

Reset network settings if nothing else works

If you have tried restarting, updating, forgetting the network, and checking for interference and the TV still will not connect, reset the network settings to factory defaults. Go to Settings > General > Reset > Reset Network Settings. The TV will restart and all saved WiFi networks will be erased.

After the reset, go back to Network Settings and reconnect to your WiFi. This clears any corrupted configuration that survived the earlier troubleshooting steps. If the TV connects after a network reset but fails again after a few days, the problem may be with your router rather than the TV — try connecting other devices to see if they have the same issue.

Frequently Asked Questions

Why does my Samsung TV connect to WiFi but then disconnect after a few minutes?

This usually means interference or a weak signal. Move the router closer, switch to 5 GHz if available, or remove obstacles between the TV and router. If the problem persists, restart the router and forget the network on the TV, then reconnect. If disconnections happen at the same time every day, a neighbor's WiFi network may be interfering — check your available networks list and see if a new network appears at that time.

Can I use a WiFi extender to improve my Samsung TV's connection?

Yes, but extenders sometimes cause their own problems because they create a separate network with a different name. If you use an extender, make sure the TV connects to the main router network, not the extender network, because the extender may drop the connection more often than a direct router connection. A mesh WiFi system is more reliable than an extender if you need coverage in a distant room.

What if my Samsung TV is too old to support my router's WiFi standard?

Older Samsung TVs may not support WiFi 6 or the latest security standards. Check your TV's manual or Samsung's support page for your model number to see which WiFi standards it supports. If your router is very new, try switching it to a compatibility mode that broadcasts older standards, or use a wired ethernet connection instead.

Does a factory reset erase my apps and settings?

A network reset only erases saved WiFi networks and network settings — it does not touch your apps, accounts, or picture settings. A full factory reset would erase everything, but that is not necessary for WiFi problems. Stick with the network reset unless Samsung support specifically tells you to do a full reset.
