Samsung TV Not Connecting to Wi-Fi: Fix Guide

A Samsung TV that won't join Wi-Fi is almost always a software or signal issue, not a broken Wi-Fi chip — so work the quick fixes before anything drastic. The usual causes are a stale network cache, the TV trying the wrong band, or a DNS hiccup. One Samsung-specific reset clears the majority of cases.

Start here: the fixes that work most often

1. Reset network settings — the #1 fix. Settings > General > Network > Reset Network, then reconnect. This wipes a corrupted network cache that blocks the connection and survives normal restarts.
2. Power-cycle the TV and router. Unplug both for at least 30 seconds. Restart the router first, let it fully come up, then power the TV — a stale router lease is a common cause.
3. Re-enter the password carefully. A wrong character (case-sensitive) reads as "can't connect." Re-type it and watch for autocaps.

If it sees the network but won't connect

1. Check the band. If your router broadcasts 2.4GHz and 5GHz on separate names, try the 2.4GHz network — it reaches farther and some Samsung models are pickier on 5GHz. If both bands share one name, the issue is elsewhere.
2. Set DNS manually. Network > Network Status > IP Settings > DNS Setting > Enter Manually > 8.8.8.8. A DNS failure lets the TV "connect" but blocks internet/apps and can stall the join. The same manual-DNS fix clears Samsung's error 107 internet-connection failure.
3. Check for a software update — if you can, via a phone hotspot or temporary Ethernet: Settings > Support > Software Update. A firmware bug can break Wi-Fi until patched.

If it connects but keeps dropping

That's signal strength. Move the router closer, add an extender near the TV, or run Ethernet for a rock-solid link. A TV far from the router drops Wi-Fi that a phone in your hand holds fine.

Last resort

Settings > General > Reset (factory reset) clears deeper software faults — back up nothing-needed and re-run setup. If Wi-Fi fails even after a factory reset and a wired connection works, the wireless module may need service.

FAQ

What's the fastest fix for Samsung Wi-Fi problems? Reset Network (Settings > General > Network > Reset Network), then power-cycle the router and TV for 30+ seconds. That clears most cases.

It connects but says no internet. That's usually DNS. Set DNS manually to 8.8.8.8 in Network Status > IP Settings. The same bad-DNS path is also why a Samsung TV won't download apps even when it looks online.

Should I use 2.4GHz or 5GHz? Try 2.4GHz if the bands have separate names — it reaches farther and some Samsung sets are fussy on 5GHz. Use 5GHz only when the router is close.

It keeps dropping after connecting. Weak signal. Add an extender near the TV or wire it with Ethernet.
