Samsung TV keeps disconnecting from Wi-Fi, won’t stay connected or drops internet while streaming
Technician
To start, can you tell me:
• Exact TV model (for example: Samsung QLED, Crystal UHD, The Frame) and roughly what year it’s from?
• Whether it’s connected over Wi-Fi or Ethernet cable right now?
• What you actually see when it drops — “Unable to connect to network”, “Wireless network disconnected”, error code like 102 or 107, or apps saying “no internet connection”?
• Does your phone/laptop stay online on the same Wi-Fi when the Samsung Smart TV loses connection?
With that we can narrow down if your Samsung TV Wi-Fi keeps disconnecting because of the router, the TV’s network settings, or a known Smart TV bug.
Technician
Most of the time, a Samsung Smart TV Wi-Fi keeps dropping situation comes down to one (or a mix) of these:
• Slight Wi-Fi instability or weak signal right where the TV sits (even when phones are fine).
• Outdated TV firmware that has bugs maintaining Wi-Fi or handling network errors (error 102/107).
• Glitched network settings on the TV — bad IP/DNS data, old network profile, or DHCP issues.
• Router options like MAC filtering, band steering, IPv6 causing the TV to drop while other devices stay connected.
We’ll move through a proven sequence: 1) refresh TV & router, 2) check Network Status on the Samsung TV, 3) reset and re-add Wi-Fi, 4) adjust IP/DNS, 5) update firmware & Smart Hub, 6) test a wired/Ethernet or alternate network. I’ll keep each step clear.
Technician
Step 1 — Soft reset your Samsung TV and router
1) With the TV on, hold the Power button on the remote until the TV fully shuts down and the Samsung logo appears, or unplug it from the wall.
2) Unplug your Wi-Fi router/modem for 30–60 seconds.
3) Plug the router back in first and wait 1–2 minutes until all lights are normal and Wi-Fi is up again.
4) Plug the TV back in and power it on.
Step 2 — Check Network Status on the Samsung TV
• On the TV, go to Settings → All Settings → Connection → Network → Network Status (or Settings → General → Network → Network Status on some models).
• Let it run and tell me what you see: “Connected to the internet”, an error code (102, 107, 13), or a red X between the TV and router/internet.
This tells us if your Samsung TV Wi-Fi not working consistently is due to the local Wi-Fi, or a specific DNS/IP problem.
Technician
Step 3 — Forget and re-add the Wi-Fi network
1) Go to Settings → All Settings → Connection → Network → Open Network Settings → Wireless.
2) Highlight your Wi-Fi network, choose Manage / Forget / Delete (label varies), and confirm.
3) Then select your Wi-Fi again, enter the password carefully, and connect.
Step 4 — Check IP and DNS settings
1) While still in Network Status, select IP Settings.
2) Make sure IP setting is on Get automatically (DHCP) unless your internet provider told you otherwise.
3) For DNS setting, if it’s “Get automatically”, temporarily switch to Enter Manually and set
8.8.8.8.4) If it was already manual with some old address, set it back to Get automatically and test again.
After this, try streaming YouTube or Netflix for 15–20 minutes. Let me know if the Samsung TV keeps disconnecting from Wi-Fi or if it seems more stable.
Technician
Step 5 — Reset the network on the Samsung TV
1) Go to Settings → All Settings → Connection → Network → Reset Network (on some models: Settings → General → Network → Reset Network).
2) Confirm the reset; the TV will drop all saved Wi-Fi networks.
3) After it finishes, go back to Open Network Settings, choose your Wi-Fi and reconnect.
Step 6 — Update TV firmware (Tizen)
1) Go to Settings → All Settings → Support → Software Update (or Settings → Support → Software Update).
2) Enable Auto Update and select Update Now / Check for Updates.
3) If an update is available, install it and let the TV restart fully — don’t interrupt this.
Step 7 — Quick Smart Hub refresh (optional but helpful)
• Some models have Self Diagnosis under Settings → Support where you can choose Reset Smart Hub to clear deeper glitches related to apps and network.
After the network reset and firmware update, test again: stream an app or run YouTube for 20–30 minutes. Tell me if the Samsung TV still keeps losing Wi-Fi or if the drops are less frequent.
Technician
Step 8 — Check Wi-Fi strength where the Samsung TV sits
1) On the TV, go to Settings → General/Connection → Network → Open Network Settings → Wireless and look at the Wi-Fi signal bars.
2) If you only see 1–2 bars, the TV is on the edge of coverage — that’s when a Samsung Smart TV keeps dropping Wi-Fi under load.
Step 9 — Try a different band or wired connection
• If your router has both 2.4 GHz and 5 GHz, try connecting the TV to the one with the stronger signal and less congestion.
• If possible, temporarily connect the TV with an Ethernet cable from the router or a Wi-Fi extender and test for an evening. If the Samsung TV disconnects from Wi-Fi but is rock-solid on Ethernet, we know it’s purely a wireless issue (range, interference, or the TV’s Wi-Fi module being fussy).
Step 10 — Basic router-side checks
• Make sure the TV is not on a guest network with stricter rules.
• If your router has strong MAC filtering or advanced security, ensure the TV’s MAC address isn’t blocked.
• In some cases, disabling IPv6 for the TV’s network profile or turning off aggressive “smart connect / band steering” can help when a Samsung TV keeps disconnecting from the router for no clear reason.
Try Ethernet if you can, or move the router a bit closer, then test again and tell me whether the drops continue.
Technician
Step 11 — Improve Wi-Fi where the Samsung TV is
• If you can, move the router higher, more central, and closer to the TV — fewer walls and no big metal cabinets in between.
• Another great option is to use a Wi-Fi extender / mesh node or powerline adapter near the TV and either connect the TV to that node via Wi-Fi or Ethernet. This often completely stops a Samsung Smart TV from disconnecting from Wi-Fi every few minutes.
Step 12 — Keep the network clean
• Avoid overloading the network with big downloads or multiple 4K streams on the same band while the TV is streaming.
• If your router allows it, give the TV a DHCP reservation so it always gets the same IP address; this can prevent the TV from dropping when leases renew.
After moving the router or adding an extender, switch the TV back to Wi-Fi and test for another evening. If the Samsung TV no longer disconnects from Wi-Fi, you’ll know the fix was signal quality rather than settings.
Technician
Step 13 — Prevent future disconnects
• Keep Auto Update on under Settings → Support → Software Update so firmware bugs related to Wi-Fi get patched.
• Every week or two, power the TV and router off fully (not just standby) for 30 seconds to clear memory and renew network leases cleanly.
• If you ever see error code 102 or 107 again, repeat the quick version: run Network Status, Reset Network, and reboot the router.
• If the TV ever stops seeing any Wi-Fi networks or shows “MAC address failed” in Network Status, that can indicate a failing Wi-Fi module — in that case, using Ethernet permanently or booking service through Samsung may be the best move.
If you want, I can also help you optimize picture and app settings now that the Samsung Smart TV stays connected to Wi-Fi. Just open the chat and share your exact model number.

Quick answer: the accepted fix
Accepted fix when your Samsung TV keeps disconnecting from Wi-Fi: fully power-cycle the TV and router, then run Network Status under Settings → Connection/Network. Next, reset the network on the TV, reconnect to Wi-Fi, and update the TV’s software/firmware. If the TV still won’t stay connected, set DNS to 8.8.8.8, test a wired Ethernet connection, and improve Wi-Fi coverage with a closer router or extender.
Why your Samsung TV keeps disconnecting from Wi-Fi
Most Samsung TV keeps disconnecting problems come from a handful of causes: weak or unstable Wi-Fi signal where the TV sits, outdated firmware that struggles to hold a network connection, corrupted network settings on the TV, or router features like MAC filtering and band steering that confuse the TV. If the TV shows “connected” but then drops streaming apps or throws network error codes (102, 107), start with a power cycle, Network Status check, and network reset, then move on to DNS and firmware updates before assuming the hardware is bad.
How to verify your Samsung TV Wi-Fi issue is fixed
To confirm your Samsung Smart TV Wi-Fi keeps disconnecting issue is solved, test more than just one app. Stream Netflix or Prime Video for 20–30 minutes, then switch to YouTube or another app. The TV should stay online without showing “unable to connect to network” or forcing you back into Wi-Fi settings. Also, turn the TV off for a while and back on: if it reconnects automatically every time and your Samsung TV no longer disconnects from Wi-Fi during normal use, your fix is stable. If Ethernet is always solid but Wi-Fi still drops, that’s your sign to focus on improving wireless coverage or using a wired connection permanently.
Samsung TV keeps disconnecting — quick troubleshooting tips
Most Samsung Wi-Fi issues are fixed by refreshing network settings, updating firmware and improving signal.
Quick path: restart the TV and router, run Network Status, then Reset Network on the Samsung TV and reconnect to Wi-Fi. Set IP to automatic and try DNS 8.8.8.8, then install any available software update. If your Samsung TV keeps disconnecting from Wi-Fi but works on Ethernet, move the router closer or add a Wi-Fi extender so the signal at the TV is strong and stable.

FAQ
Why does my Samsung TV keep disconnecting from Wi-Fi?
Most Samsung TV keeps disconnecting from Wi-Fi issues are caused by weak signal at the TV, outdated firmware, or corrupted network settings. Start by power-cycling the TV and router, running Network Status, and resetting the network in Settings → Connection/Network. Updating firmware and improving Wi-Fi coverage near the TV usually stabilizes the connection.
How do I stop my Samsung TV from disconnecting from Wi-Fi?
To stop a Samsung Smart TV from disconnecting from Wi-Fi, reset the TV’s Network settings, reconnect to Wi-Fi, and check IP/DNS values (use automatic IP and try DNS 8.8.8.8). Then install the latest software update. If the TV is stable on Ethernet but not wireless, move the router closer or use a Wi-Fi extender or mesh node near the TV.
What does Samsung TV network error 102 or 107 mean?
Samsung TV error 102/107 generally points to a Smart Hub or internet connectivity problem — the TV can’t maintain a stable connection to Samsung or app servers. Reboot the router and TV, run Network Status, reset the network, update firmware, and double-check DNS settings. If the TV keeps showing these errors on Wi-Fi but not on Ethernet, treat it as a wireless stability issue.
When should I factory reset my Samsung TV for Wi-Fi issues?
A full factory reset is a last resort for when a Samsung TV won’t connect to Wi-Fi even after network reset, firmware update, and router checks. If Network Status shows MAC address errors or the TV can’t see any Wi-Fi networks, back up your settings, then go to Settings → General & Privacy → Reset (or Support → Self Diagnosis → Reset) and re-set the TV from scratch. If problems persist after that, it’s time to contact Samsung support or an expert for hardware diagnosis.
