Fix “Samsung TV won’t connect to Wi-Fi” — no network, errors & Wi-Fi disconnects

Technician avatar Technician
Hi! We’ll get your Samsung TV won’t connect to Wi-Fi issue fixed so apps go online again instead of showing network errors.

First, what kind of message do you see on the Samsung Smart TV — “Unable to connect to network”, “No network detected”, “Wireless network disconnected”, or an error code like 107 or 105?

Can other devices (phone, laptop) connect to the same Wi-Fi without problems? And is the TV close to the router on Wi-Fi, or are you using Ethernet? Finally, has this Samsung TV not connecting to Wi-Fi problem just started recently after a power cut, new router, or software update, or has it been happening for a long time?
Customer
It’s a Samsung Smart TV from a few years ago. When I go to Network settings and try to connect, it either says “Unable to connect to network” or gives error code 107. Sometimes it doesn’t even show my home Wi-Fi in the list, just a few random networks from neighbors.

My phone and laptop connect fine to the same Wi-Fi, so the internet is working. The TV used to work before, but all of a sudden the Samsung TV Wi-Fi stopped working. Restarting the router and TV hasn’t helped so far.

Thanks, that helps a lot. A Samsung TV won’t connect to Wi-Fi situation usually comes from one of three places:

• The TV’s saved network settings are corrupted, so it can’t join any wireless network until you reset network settings on the Samsung TV.
• The router has changed (new SSID/password, different band, MAC filtering, or DNS issues), so the TV can’t get a proper IP address or DNS resolution.
• In rarer cases, the TV’s wireless module or MAC address is having trouble, which you can sometimes see in Network Status as “MAC address failed”.

We’ll go step by step like Samsung suggests in their own troubleshooting: run Network Status, reset the TV’s Wi-Fi profile, check 2.4 GHz vs 5 GHz, and apply simple router/DNS tweaks so your Samsung Smart TV connects to Wi-Fi again and stays online.
Customer
I didn’t change the router recently, except my ISP gave me a new modem/router combo a couple of months ago. Phones, tablets, and a laptop all connect with no problem.

On the TV, sometimes I see my Wi-Fi name but it fails after entering the password, and sometimes it just says no networks found. I haven’t touched any IP or DNS settings, and I don’t think I’ve done a network reset on the Samsung TV before.
Technician avatar Technician
Perfect — we’ll start right on the TV side, where most Samsung TV not connecting to Wi-Fi cases are fixed.

Step A — Network Status & clean network reset on the TV
1) On the Samsung TV remote, go to Settings > General > Network > Network Status. Let it run the test and note if it shows a red X between the TV and router, or between router and internet.
2) Still in Network, choose Reset Network. Confirm, let the TV restart if needed. This wipes old Wi-Fi profiles that can block connections.
3) After the reset, go to Open Network Settings > Wireless. Wait a moment to see if your home Wi-Fi SSID appears in the list.
4) If your network appears, select it, re-enter the Wi-Fi password carefully (watch for capital letters), and try connecting again.

If the Samsung TV still won’t connect to Wi-Fi or doesn’t see your network, we’ll try a phone hotspot next. That helps us see if the TV can connect to any Wi-Fi at all or only fails with your home router.
Customer
I ran Network Status; it shows a red X between the TV and the router. After doing Reset Network and rebooting, my home network appeared in the list again. I entered the password, but it still said “Unable to connect to network (error 107)”.

I tried turning on my phone’s hotspot and connecting the Samsung TV to that — surprisingly, the TV connected to the hotspot fine and apps worked. It’s just the home Wi-Fi network that it refuses to join.
Technician avatar Technician
That test is really useful: it proves the TV’s Wi-Fi radio still works, so we can focus on how the Samsung TV and router talk to each other.

Step B — Adjust Wi-Fi band, SSID and basic IP/DNS for the TV
• In your router admin page, check if you have separate 2.4 GHz and 5 GHz Wi-Fi. Many Samsung TVs are more stable on 2.4 GHz for range, while newer ones work well on both. If both bands share the same name, temporarily give the 2.4 GHz band a unique SSID like “Home-2G” and the 5 GHz band “Home-5G”.
• On the TV, under Open Network Settings > Wireless, try connecting to the 2.4 GHz network first. That often fixes Samsung TV can’t connect to Wi-Fi issues caused by distance or 5 GHz quirks.
• Next, in Network Status > IP Settings, set DNS to “Enter Manually” and type 8.8.8.8 or your ISP’s DNS. Leave IP assignment on “Automatic/DHCP”. Many people find error 107 disappears after forcing a stable DNS.
• Make sure your router doesn’t have MAC address filtering turned on for Wi-Fi, or if it does, add the Samsung TV’s MAC address (shown in Network Status) to the allowed list.

When that’s done, try reconnecting the TV to the home Wi-Fi again and let me know if the “Samsung TV won’t connect to Wi-Fi” error changes or if it finally stays connected.
Customer
I logged into the router and gave the 2.4 GHz and 5 GHz different names. The TV connected to the 2.4 GHz network on the first try after that.

I also set DNS to 8.8.8.8 in the TV’s IP settings and left IP on Auto. Now the Samsung TV connects to Wi-Fi and passes the Network Status test, but after a while it sometimes disconnects and says “network cable unplugged or wireless network disconnected” and I have to reconnect it.
Technician avatar Technician
Good progress: we fixed the basic “won’t connect” problem — now we just need to stop the Samsung TV Wi-Fi from dropping after it connects.

Step C — Stabilize Wi-Fi (signal strength, channel, router load)
1) On the TV, go to Settings > General > Network > Network Status and check the signal bars. If it’s only 1–2 bars, move the router a bit closer, higher, and out of cabinets to improve Samsung TV wireless signal strength.
2) In the router’s 2.4 GHz settings, set a fixed channel (1, 6, or 11) instead of “Auto”. This can stop random channel changes that disconnect older TVs.
3) If many devices are streaming and gaming at the same time, enable QoS / Media / Streaming priority and set the Samsung TV as a high-priority device so it keeps its connection when your network is busy.
4) Power-cycle both TV and router properly: unplug both for 60 seconds, then plug in the router, wait for Wi-Fi to come back, and only then power the TV. This simple sequence clears a lot of “Samsung TV keeps disconnecting from Wi-Fi” complaints.

After these changes, watch a streaming app for 15–20 minutes and see if the Samsung TV Wi-Fi connection still drops, or if it now stays connected.
Customer
Signal strength shows 3 full bars now after I moved the router out of the cabinet and a bit closer. I also set the 2.4 GHz channel to 6 and turned on a “Video Streaming” QoS mode with the TV prioritized.

After the reboot sequence, the Samsung TV stayed connected for about an hour while we watched Netflix with no issues. So far there have been no random disconnects or “no network detected” messages. Is there anything else I should change on the TV itself so the Wi-Fi connection doesn’t break again?
Technician avatar Technician
That sounds much better already. To really lock this in, we’ll clean up software and app layers that often cause stubborn Samsung TV network errors even after Wi-Fi is fixed.

Step D — Update software & Smart Hub for Samsung TV Wi-Fi issues
• While the TV is online, go to Settings > Support > Software Update > Update Now and install any pending updates. Samsung specifically mentions software updates as a fix when a Samsung TV won’t connect to Wi-Fi or shows error 107.
• After updating, check Settings > General > System Manager > Time and make sure the date and time are correct or set to “Auto”. Incorrect time can break secure connections to apps and make it look like the TV lost internet.
• If certain apps still misbehave, you can go to Settings > Support > Device Care (on newer models) and run diagnostics, or use the menu to Reset Smart Hub. This logs you out of apps and clears cached data that sometimes blocks Wi-Fi sign-ins.

Between a stable Wi-Fi signal, corrected DNS/IP settings and clean apps, most Samsung Smart TV not connecting to Wi-Fi issues stop coming back.
Customer
I updated the TV’s software and the date/time was slightly off, so I set it to automatic. I haven’t needed to reset Smart Hub yet because everything seems to be working again.

The TV now connects to my home Wi-Fi every time I turn it on, and apps load like normal. If this problem shows up again later, what’s the best order to check things so I don’t have to guess?
Technician avatar Technician
Great question — a simple checklist makes future Wi-Fi problems much easier to fix.

Step E — If your Samsung TV won’t connect to Wi-Fi again, check in this order
1) Other devices: make sure phones/laptops can get online on the same Wi-Fi; if they can’t, you’re dealing with a router/ISP outage, not just the TV.
2) Network Status on the TV: run the test and see where the red X appears (TV->router or router->internet). This tells you if it’s a local Wi-Fi issue or an upstream problem.
3) Reset Network on the TV, then reconnect to the correct 2.4/5 GHz network with the right password and DNS on Auto or 8.8.8.8.
4) Router band/channel: confirm the TV is on the band that works best in its location and that channels aren’t constantly hopping.
5) If MAC address failed appears or the TV won’t see any networks at all (not even your hotspot), back up your settings and consider a factory reset of the Samsung TV. If even that doesn’t fix it, the Wi-Fi module may need service.

Keeping your router in an open place, avoiding overcrowded guest networks and letting the TV update regularly will prevent a lot of those “Samsung TV won’t connect to Wi-Fi” days before they begin.
Customer
That all makes sense. I’ve written down the steps, especially the part about using Network Status to see where the problem is. For now the Samsung TV connects to Wi-Fi right away and stays online.

Thanks for helping me figure out why the Samsung TV wouldn’t connect to Wi-Fi while everything else worked fine.
Technician avatar Technician
You’re welcome — glad we could get your Samsung Smart TV back online.

Summary: To fix a Samsung TV that won’t connect to Wi-Fi, run Network Status, do a full Reset Network, connect to a clear 2.4 or 5 GHz SSID with the correct password, adjust DNS/IP settings, then stabilize Wi-Fi with better router placement and QoS. Finally, update the TV’s software and, if needed, reset Smart Hub. If you ever see error codes or “Unable to connect to network” again, you can open a chat with an expert and we’ll trace the issue with you live.
Customer
Perfect, the step-by-step approach really helped. Now I know what to do if the Samsung TV Wi-Fi connection ever acts up again, instead of just rebooting everything randomly.

Quick answer: the accepted fix

Accepted fix when a Samsung TV won’t connect to Wi-Fi: run Network Status, Reset Network, and reconnect to a stable 2.4/5 GHz SSID with the correct password and DNS, then move the router into the open, set a clean channel, enable streaming QoS and update the TV’s software so the wireless connection stays online.

Why Samsung TVs won’t connect to Wi-Fi (2.4 GHz vs 5 GHz, DNS, router settings)

Most Samsung TV won’t connect to Wi-Fi problems come down to a mismatch between the TV’s saved network settings and what the router expects. If the router password changed, the Wi-Fi band was split, or DNS/IP got corrupted, the TV may show error 107, “unable to connect to network” or simply fail to see your home Wi-Fi while phones still work.

Samsung recommends starting with Network Status to see where the connection fails, then using Reset Network and trying a different band (2.4 GHz vs 5 GHz). Setting DNS to manual (for example 8.8.8.8), avoiding MAC filtering, and placing the router in an open location often resolve “Samsung Smart TV not connecting to Wi-Fi” without needing hardware repair.

How to check if the issue is your Samsung TV, router, or ISP

To narrow down a Samsung TV Wi-Fi problem, you want to test each piece separately.

First, confirm that other devices on the same network can reach the internet. If your phone and laptop also can’t connect, you may have a router or ISP outage rather than a TV issue. If they work but the Samsung TV can’t connect to Wi-Fi, focus on the TV’s network settings.

Next, connect the TV to a phone hotspot. If the TV connects to the hotspot but not to your home Wi-Fi, the TV’s Wi-Fi module is fine and the problem is likely router settings, Wi-Fi band, or DHCP/DNS. If it can’t see any networks at all, even a hotspot, then a hardware issue with the Samsung TV wireless adapter is more likely and you may need service after trying a full factory reset.

Samsung TV won’t connect to Wi-Fi — quick troubleshooting tips

Reset the TV’s network, pick the right Wi-Fi band, then tune router and DNS settings.

Fast path: run Network Status on your Samsung TV → choose Reset Network and reconnect to the correct 2.4 or 5 GHz Wi-Fi with the right password → set DNS manually if needed → move the router into the open, closer to the TV → set a fixed Wi-Fi channel and enable streaming/QoS priority for the TV → then update TV software and, if apps still misbehave, reset Smart Hub for a clean start.

FAQ

Why won’t my Samsung TV connect to Wi-Fi?

A Samsung TV won’t connect to Wi-Fi when the TV can’t talk properly to your router. Common causes include an incorrect Wi-Fi password, outdated or corrupted network settings on the TV, DNS/IP conflicts, MAC filtering on the router, or weak Wi-Fi signal. Running Network Status, resetting the network, and reconnecting to a stable 2.4 or 5 GHz SSID usually reveals whether it’s a TV setting, a router configuration, or an ISP issue.

How do I fix Samsung TV error 107 or “Unable to connect to network”?

For error 107 and similar “Unable to connect to network” messages, start with Settings > General > Network > Network Status and then choose Reset Network. After the TV restarts, reconnect to your Wi-Fi with the correct password, then in IP Settings set DNS to Auto or manually to 8.8.8.8. If the error persists, move the router closer, try a different band (2.4 vs 5 GHz), and make sure the router doesn’t block new devices with MAC filtering.

Why does my Samsung TV keep disconnecting from Wi-Fi?

If your Samsung TV keeps disconnecting from Wi-Fi after it connects, the usual culprits are weak signal, crowded Wi-Fi channels, overloaded routers, or power-saving features. Check Wi-Fi signal bars in Network Status, move the router into the open, set a fixed channel, and enable QoS or streaming priority for the TV. Keeping the TV’s software updated and occasionally rebooting both TV and router helps prevent random drops.

When should I factory reset or repair my Samsung TV for Wi-Fi issues?

If you’ve tried Network Reset, band changes, DNS/IP tweaks, router placement and software updates but your Samsung Smart TV still won’t connect to Wi-Fi — especially if it shows “MAC address failed” or can’t see any wireless networks including a phone hotspot — the internal Wi-Fi module may be faulty. At that point, back up settings, try a full factory reset, and if the issue persists, contact Samsung support or a repair technician to diagnose the hardware.
