Fix “Samsung TV Unable to Connect to Network” — Wi-Fi, DNS & IP settings

Technician avatar Technician
Hi! We’ll get your Samsung TV “Unable to connect to network” error fixed so apps and streaming work again instead of failing to connect.

First, a couple of quick questions so we target the right fix:

• Which Samsung Smart TV model and year do you have (for example, NU7100, Q60, Frame, etc.)?
• Are you connecting over Wi-Fi or Ethernet cable? If Wi-Fi, is it 2.4 GHz, 5 GHz, or you’re not sure?
• On-screen, does it only say “Unable to connect to network” or do you also see a network error code like 101, 102, 107 or 202?
• Finally, are other devices (phone, laptop) working fine on the same Wi-Fi network right now, or is everything offline?

With that, we’ll work through the fastest Samsung TV not connecting to Wi-Fi fixes step by step — no random guessing in the menus.
Customer
It’s a Samsung Smart TV from a few years ago (UE55 series I think). I use Wi-Fi, not a cable. When I run the network test it says “Unable to connect to network” and sometimes shows error code 107. My phone and laptop connect to the same Wi-Fi with no problem. I’ve tried restarting the router, but the Samsung TV still won’t connect to Wi-Fi and none of the apps will load.
Technician avatar Technician
Thanks, that helps a lot. On Samsung, network error 107 usually means the TV can see the router but can’t reach the internet or DNS servers properly.

Most Samsung TV unable to connect to network issues come from one of these:

• Saved Wi-Fi details on the TV are corrupted (wrong password cached or glitchy profile).
• The router is blocking the TV’s IP or MAC address, or the DHCP lease is stuck.
• The TV’s IP settings / DNS are misconfigured (for example, DNS server not responding).
• Old TV firmware or a buggy Smart Hub update that breaks Samsung Smart TV network connection until you reset the network.

We’ll start by making the TV forget the current Wi-Fi profile and do a clean network reset, then we’ll set manual DNS (8.8.8.8) and check if the router is handing out a proper IP address.
Customer
Got it. I don’t think I changed anything; it just started doing this one day. Network Status on the TV shows my Wi-Fi name, but there’s an “X” between the TV and the router symbol. It keeps saying “Unable to connect to network” when I try again. I’ve re-entered the Wi-Fi password but it still fails. Other devices stream Netflix fine, so it really seems like only the Samsung TV can’t connect to the network.
Technician avatar Technician
Perfect, that description matches a typical Samsung Smart TV not connecting to Wi-Fi case.

Step A — Clean restart and Wi-Fi profile reset on the TV
1) With the TV on, press and hold the Power button on the remote until the Samsung logo appears and the TV restarts. That’s a soft reset (clears cached network glitches without wiping apps).
2) After it boots, go to Settings → General → Network → Open Network Settings → Wireless. Highlight your home network, choose Forget / Disconnect (or remove the network), then re-select it and re-enter the Wi-Fi password carefully.
3) If it still shows “Unable to connect to network”, turn on a mobile hotspot on your phone, place it near the TV, and try connecting the Samsung TV to that temporary Wi-Fi.

• If the TV connects fine to the hotspot, the problem is more on the router / home Wi-Fi side.
• If the TV also fails on the hotspot, we focus on TV network settings, DNS and firmware next.

Try those steps now and tell me what happens when you test your home Wi-Fi and then the phone hotspot.
Customer
I did the soft reset and removed the old Wi-Fi network. After reconnecting, it still said unable to connect to network. Then I tried my phone’s hotspot right next to the TV and interestingly it connected to the hotspot and Netflix worked there. So the Samsung TV can get online, but only through the hotspot, not my main Wi-Fi network.
Technician avatar Technician
Great troubleshooting — that proves the Samsung TV’s Wi-Fi module still works. The issue is between the TV and your home router.

Step B — Fix router / Wi-Fi settings so the Samsung TV can connect
1) On the router, temporarily reboot the modem and router (unplug for 30–60 seconds, then power on the modem, then router, then TV). This clears stuck DHCP leases that often cause error 107 or 102 on Samsung TVs.
2) In the router’s wireless settings, make sure your main network is using WPA2-PSK or WPA3-Personal security (not WEP, enterprise, or open guest mode that blocks devices).
3) Disable any MAC address filtering / access control lists for now, or add the TV’s MAC address to the allowed list so it’s not blocked from the network.
4) If your router merges 2.4 GHz and 5 GHz into one SSID (often called “Smart Connect”), try splitting the bands and giving the 2.4 GHz network its own name (for example, “Home-2G”). Older Samsung TVs are often more stable on 2.4 GHz for basic streaming.
5) Back on the TV, go to Settings → General → Network → Network Status and run the test again on your home Wi-Fi.

Let me know: after the router reboot and these changes, does the Samsung TV still say Unable to connect to network, or do you get a slightly different message or error code?
Customer
I rebooted the modem and router, turned off the access control feature, and split the Wi-Fi so 2.4 GHz has its own name. The TV now connects to the 2.4 GHz network, but sometimes I still get network error 107 when I open certain apps. The Network Status test sometimes shows the TV connected to the router but an “X” between router and internet. So it’s better, but not fully fixed.
Technician avatar Technician
That’s progress — we’ve fixed the Wi-Fi association, now we just need to stabilize how the TV reaches the internet and DNS.

Step C — Set manual DNS and run a full Samsung TV network reset
1) On the TV, go to Settings → General → Network → Network Status. When the test finishes, choose IP Settings.
2) Leave IP setting = Auto, but change DNS setting from “Automatic” to Manual, and enter 8.8.8.8 (Google DNS). Confirm and let the TV retest the connection.
3) If apps are still flaky, go to Settings → General → Network → Reset Network. Confirm the Samsung TV network reset so it clears all old Wi-Fi profiles and IP data, then set up the Wi-Fi connection again from scratch.
4) After reconnecting, open a couple of apps (YouTube, Netflix, Samsung TV Plus) and see if the “Unable to connect to network” message or error code 107 still appears.

Manual DNS plus a full network reset fixes most Samsung TV not connecting to network cases where the router itself is fine.
Customer
Switching DNS to 8.8.8.8 and doing the network reset seems to have helped a lot. The TV now connects to Wi-Fi right away and most apps open normally. I did see the unable to connect message briefly once when starting a streaming app, but when I tried again it worked. Is there anything else I should change in the Samsung settings so this doesn’t come back?
Technician avatar Technician
Nice — that’s exactly what we want: the Samsung Smart TV connects to Wi-Fi and apps mostly work, with only an occasional hiccup.

To make the fix more permanent:

• Go to Settings → Support → Software Update → Update Now and install any pending Samsung TV firmware update. Many updates specifically improve network and app reliability.
• If certain apps still show “Unable to connect”, open Settings → Support → Self Diagnosis → Reset Smart Hub. This clears cached app data and re-authenticates with Samsung’s servers (you’ll just sign back into apps afterward).
• If you can, try running a wired Ethernet cable from the router to the TV. Even if you mainly use Wi-Fi, testing Ethernet tells us if the remaining glitch is purely wireless or something else on the TV.

After the software update and, if needed, a Smart Hub reset, we’ll lock in a stable Samsung TV network connection so that “unable to connect” message becomes rare or disappears entirely.
Customer
I updated the software (there was a new version) and did a Smart Hub reset. I also tried an Ethernet cable as a test, and with that the TV connects instantly and never shows the error. On Wi-Fi it’s now pretty solid too — no more constant “Unable to connect to network”, just an occasional hiccup if the Wi-Fi is busy. So it seems much more stable overall.
Technician avatar Technician
Excellent — that tells us everything from the router to DNS is now behaving, and the TV’s software is up to date.

To stop Samsung TV network errors from creeping back:

• Leave the TV on the 2.4 GHz network if the signal is stronger there, or move the router closer if you want to use 5 GHz for higher speeds.
• Avoid hiding the router behind the TV or in a cabinet; keeping it in the open reduces Wi-Fi interference that can trigger random disconnects.
• Once your settings work, grab a photo of your Samsung TV IP settings / DNS (8.8.8.8), Network Status screen and Wi-Fi password so you can quickly re-create the setup after a factory reset or router replacement.
• Every few months, power-cycle both the TV and router to clear out old sessions and renew DHCP leases — this alone can prevent a lot of “Samsung TV can’t connect to network” complaints.

Follow those habits and you’re much less likely to see error 101 / 102 / 107 or the “Unable to connect to network” message again.
Customer
That makes sense. I’ll keep the router out in the open and leave the TV on the 2.4 GHz network with the DNS set to 8.8.8.8. After all these steps, my Samsung TV connects to Wi-Fi every time and all the apps load normally. No more “Unable to connect to network” messages so far. Thanks for walking me through it.
Technician avatar Technician
You’re welcome — glad we could get your Samsung Smart TV back online.

Summary: To fix a Samsung TV “Unable to connect to network” error, reset the TV and router, forget and re-add Wi-Fi, split 2.4/5 GHz if needed, set manual DNS (8.8.8.8), run a Samsung network reset, and install the latest firmware and Smart Hub updates. Testing with Ethernet is a great way to confirm the Wi-Fi is the only weak link.

If the error ever returns — or if you see new network error codes like 102, 107 or 202 — you can open a chat with an expert and we’ll trace the issue live with you, step by step.
Customer
Sounds good. I’ve taken pictures of the network settings like you suggested. For now everything is working perfectly — the TV connects on its own and all the apps stream fine. Really appreciate the detailed Samsung TV Wi-Fi troubleshooting help.

Quick answer: the accepted fix

Accepted fix when a Samsung TV shows “Unable to connect to network”: reboot TV and router, forget and re-add Wi-Fi, split 2.4/5 GHz if needed, set DNS to 8.8.8.8, run a Samsung network reset, and update the TV’s firmware so Wi-Fi and apps connect reliably again.

Why Samsung TVs show “Unable to connect to network” (Wi-Fi vs wired, DNS, interference)

Most Samsung TV “Unable to connect to network” messages are caused by local network issues, not your streaming apps. The TV relies on a clean connection to your router, valid IP settings from DHCP, and a working DNS server. If any of those fail, the TV may see your Wi-Fi name but still can’t reach the internet.

Common triggers include weak or unstable Wi-Fi signal, crowded 2.4 GHz channels, routers that block new devices with access control, or TVs stuck on automatic DNS that no longer responds. Moving the router closer, using a less congested band, setting manual DNS (like 8.8.8.8), and occasionally testing with a wired Ethernet connection are all powerful ways to stabilize a Samsung Smart TV network connection.

How to tell if it’s your Samsung TV, router, or ISP causing the network error

To narrow down a Samsung Smart TV not connecting to Wi-Fi problem, compare it with other devices and a second network:

First, check whether phones and laptops can browse the web on the same Wi-Fi network. If everything is offline, you’re likely dealing with a router or ISP issue. If only the Samsung TV shows “Unable to connect to network”, try connecting it to a mobile hotspot or a temporary guest Wi-Fi. When the TV works on the hotspot but not your main router, the router’s Wi-Fi settings, DHCP, or access control rules are the main suspects.

If the TV fails on all networks — including a hotspot and wired Ethernet — even after a full network reset and firmware update, there may be a deeper problem with the TV’s Wi-Fi module that needs professional diagnosis.

Samsung TV “Unable to connect to network” — quick troubleshooting tips

Restart everything, reset the network, then tune Wi-Fi, DNS and Smart Hub.

Fast path: soft-reset your Samsung Smart TV → reboot modem and router → forget and reconnect to Wi-Fi → split 2.4/5 GHz bands if needed → set manual DNS 8.8.8.8 → run a full Samsung TV network reset → update TV firmware and, if necessary, reset Smart Hub. If Wi-Fi still misbehaves, test a wired Ethernet cable to confirm whether the issue is wireless-only.

FAQ

Why does my Samsung TV keep saying “Unable to connect to network”?

A Samsung TV “Unable to connect to network” message usually means the TV can’t get a stable IP address or reach DNS. Causes include weak Wi-Fi signal, router access control blocking the TV, DHCP glitches, or outdated TV firmware. Sometimes the Wi-Fi profile on the TV is simply corrupted and needs to be removed and re-added after a network reset.

How do I fix Samsung Smart TV not connecting to Wi-Fi?

Start by soft-resetting the TV and rebooting the router. Then forget and reconnect to Wi-Fi, preferably on a dedicated 2.4 GHz or 5 GHz network. Next, set manual DNS 8.8.8.8 in IP Settings and run a full Network Reset in the Samsung menu. Finally, update the TV’s firmware and, if needed, reset Smart Hub so streaming apps can reach the internet reliably again.

What DNS should I use when my Samsung TV can’t connect to the network?

If automatic DNS fails, switch to manual DNS in your Samsung TV’s Network Status → IP Settings screen. A common choice is 8.8.8.8 (Google DNS) or 1.1.1.1. Using a stable, public DNS often clears Samsung TV network error 107 / 102 when the router’s default DNS is slow or unresponsive.

When should I replace my router or TV for persistent Samsung network errors?

If you’ve tried reboots, network resets, manual DNS, firmware updates and even Ethernet, but your Samsung TV still can’t stay connected while other devices work fine, the TV’s Wi-Fi module may be failing. If multiple devices drop or get errors, the router may be outdated or overloaded, and upgrading to a modern Wi-Fi 5 / Wi-Fi 6 router is often the most reliable long-term fix.
