Fix “Samsung TV No IP Address” — IP auto setting failed, Wi-Fi not connecting, 0.0.0.0 IP

Technician avatar Technician
Hi! We’ll get your Samsung TV “No IP address” issue fixed so streaming apps stay online instead of dropping out. I just need a quick picture of your setup so we can target the right Wi-Fi and IP address fixes.

Which Samsung TV model / year do you have, and are you using Wi-Fi or Ethernet to connect it? On the Network Status / IP Settings screen, what exact message do you see — something like “No IP address”, “IP auto setting failed”, “Unable to obtain IP address” or an error code (e.g. 102 / 107 / 202)?

Lastly, do other devices (phones, laptops, tablets) connect fine to the same router, and is your TV on the 2.4 GHz or 5 GHz Wi-Fi network if you know? That will help us see if this is a Samsung TV issue, DHCP problem, or router configuration issue.

It’s a Samsung Smart TV, a few years old. I’m on Wi-Fi, not Ethernet. When I run Network Status it shows the TV and router, but under IP Settings it says “No IP address” and all zeros like 0.0.0.0. Sometimes I also see “IP auto setting failed. Unable to connect to network.”.

My phone, laptop and a tablet all connect to the same Wi-Fi with no problem. I think the TV is on the 2.4 GHz network, but I’m not 100% sure. Restarting the router and TV hasn’t fixed the Samsung TV Wi-Fi not connecting issue.

Thanks, that helps a lot. When a Samsung TV shows “No IP address” with 0.0.0.0, it usually means the TV never received settings from the router’s DHCP server.

Common causes are:
• TV Wi-Fi glitch or software bug so it connects to the router but doesn’t grab an IP.
• Router’s DHCP is misconfigured or temporarily stuck, so “IP auto setting” keeps failing for the Samsung TV.
• Wi-Fi issues (weak signal, interference, wrong password) that make the link unstable, especially on 5 GHz at long distance.
• Security settings like MAC address filtering or parental controls blocking the TV from getting an address.

We’ll start with quick checks (power reset and Network Status), then test automatic vs manual IP, DNS, and finally do a network reset on the Samsung TV if needed so streaming apps stop losing connection.

The router is from my ISP, and everything else works fine on it. The TV is in the living room on the other side of a wall from the router. When the problem happens, sometimes I can see my Wi-Fi network name but it just won’t connect, and when it does connect it fails on IP auto setting and shows No IP address again. I haven’t touched DHCP or any advanced router settings.

Got it. Let’s first rule out simple glitches on both the TV and router. This alone often fixes a Samsung TV no IP address / IP auto setting failed problem.

Step A — Power-cycle TV and router the “Samsung way”
1) With the TV on, press and hold the Power button on the Samsung remote until the TV turns off and the logo appears again. This does a “cold boot” (better than just turning it off).
2) Unplug the TV power cord from the wall for at least 30 seconds. While it’s unplugged, also unplug the router / modem for 30 seconds, then plug the router back in and wait until Wi-Fi is fully up.
3) Plug the TV back in and turn it on. Go to Settings → General → Network → Network Status. Let the test run and check if it still shows No IP address or if it now shows a normal IP like 192.168.x.x.
4) If your router has separate 2.4 GHz and 5 GHz SSIDs, try connecting the Samsung TV to the 2.4 GHz network first — it’s usually more stable through walls.

After doing that sequence, tell me if the TV still shows 0.0.0.0 IP or if it gets an IP but still can’t reach the internet.
Customer
I did the cold boot and unplugged both the TV and router like you said. After everything came back up, I reconnected to my Wi-Fi on 2.4 GHz this time. The TV can see the network and accepts the password, but Network Status still shows No IP address and IP stays at 0.0.0.0. It says the TV and router aren’t connected properly.
Technician avatar Technician
Thanks for checking. Since the Samsung TV still has no IP address, let’s look directly at the IP settings and try a manual configuration, which often gets around flaky DHCP.

Step B — Check IP auto setting and try a manual IP
• On the TV, go to Settings → General → Network → Network Status → IP Settings.
• Make sure IP Setting is set to “Obtain automatically” at first. If it still shows “IP auto setting failed”, we’ll switch to manual.
• On a phone or laptop that’s connected to the same Wi-Fi, check its IP details (usually under Wi-Fi → Advanced). You should see something like IP 192.168.1.20, Gateway 192.168.1.1, DNS server, etc.
• Back on the Samsung TV, set IP Setting → Enter manually and enter:
  – An IP in the same range but not used by anything else (for example 192.168.1.50).
  – Subnet mask 255.255.255.0 (if that matches your other devices).
  – Gateway equal to your router’s address (often 192.168.1.1).
  – DNS server 8.8.8.8 or your router’s IP.

Save those settings and run Network Status again. Let me know if the TV now shows a proper IP instead of 0.0.0.0 and whether streaming apps start working.
Customer
I set the IP manually like you described. Now Network Status actually shows an address (192.168.1.50) instead of no IP address, and the connection test says the TV is connected to the router and internet. Netflix and YouTube work again.

The weird thing is that after the TV sits in standby for a while, sometimes it loses connection and I get the “IP auto setting failed” or “unable to connect to network” message again until I redo things.

Great — that tells us the Wi-Fi radio is fine and the issue is mostly how the TV and router handle addressing. Let’s harden the router side so your Samsung TV Wi-Fi doesn’t keep dropping its IP.

Step C — Fix DHCP & Wi-Fi settings on the router
1) Log in to your router’s web interface or app. Under LAN / DHCP settings, make sure DHCP server is enabled and the pool has free addresses (for example 192.168.1.2–192.168.1.200).
2) If your router has an option like Address reservation / DHCP reservation, add the TV’s MAC address and reserve 192.168.1.50 for it. That way the Samsung Smart TV always gets the same IP without fighting with other devices.
3) In the Wi-Fi settings, pick a fixed channel for 2.4 GHz (1, 6 or 11) instead of Auto, and avoid crowded channels to reduce interference that can make the TV drop off and show No IP address again.
4) Turn off any strict features like MAC filtering, Access Control lists or “Block new devices” that might prevent the TV from renewing its lease.
5) Save the changes, reboot the router once, and then reboot the TV. Put the TV’s IP back to Obtain automatically and see if it now gets a stable IP from DHCP without errors.

If the Samsung TV still loses IP after that, we’ll do a Network Reset on the TV itself, which clears old Wi-Fi and IP data.
Customer
I checked the router. DHCP was on and there are plenty of addresses free. I added a DHCP reservation for the Samsung TV using its MAC and gave it 192.168.1.50, then put the TV back to “Obtain automatically”.

It connects again and shows the right IP, but every few days I still see the “Samsung TV no IP address” message or apps say there’s no internet until I run Network Status a couple times. Other devices are fine, so I’m guessing the TV’s network settings are a bit messed up.
Technician avatar Technician
That’s a good clue. When DHCP is healthy but a Samsung TV keeps dropping Wi-Fi or shows No IP address randomly, doing a full network reset plus a quick DNS tweak usually clears the cobwebs.

Step D — Reset Samsung TV network settings & adjust DNS
• On the TV go to Settings → General → Network → Reset Network. Confirm. This wipes saved Wi-Fi networks, IP and DNS settings.
• After the reset, power the TV off and back on. Then reconnect to your Wi-Fi network and keep IP Setting on “Obtain automatically”.
• In IP Settings → DNS Setting, choose Enter manually and set DNS server to 8.8.8.8 or 1.1.1.1, which can be more reliable than some ISP DNS servers.
• Check for a software update under Settings → Support → Software Update and install if available — Samsung has fixed lots of Smart TV Wi-Fi and IP bugs in updates.
• If possible, test a direct Ethernet cable connection once. If Ethernet is rock solid but Wi-Fi still drops, we know it’s purely the wireless side and can tune placement and channels further.

After the network reset and DNS change, use the TV normally for a bit and see if the “No IP address / IP auto setting failed” error comes back.
Customer
I did the Network Reset and reconnected the TV to Wi-Fi, then set DNS to 8.8.8.8 and installed a software update that was pending. Since then, it’s been a lot better — no more No IP address errors so far, and streaming apps connect faster.

I can’t easily run Ethernet to the TV right now, but Wi-Fi seems stable again. Is there anything else I should change so the Samsung TV Wi-Fi doesn’t start dropping IP addresses again in a few weeks?
Technician avatar Technician
Nice — that’s exactly what we want to see. Let’s lock in the fix so your Samsung Smart TV keeps its IP and stays online for streaming.

Step E — Keep Samsung TV Wi-Fi & IP stable long-term
• Leave the DHCP reservation in place so the TV always gets the same IP address from the router.
• Keep the TV on the more stable 2.4 GHz network unless you’re very close to the router and need 5 GHz for high-bitrate 4K streaming.
• Avoid placing the router inside cabinets or behind the TV; line-of-sight or at least higher placement usually prevents random Wi-Fi disconnects.
• Every month or so, reboot the router and TV once — this often prevents the “IP auto setting failed” bug from appearing again.
• If you ever change routers or ISP equipment, do another Network Reset on the Samsung TV so old network profiles don’t conflict.

With those in place, your TV should stop throwing No IP address or “unable to connect to network” messages. And if it ever does, you now have a clear checklist to get back online quickly.
Customer
That all makes sense. I’ll leave the reservation and 2.4 GHz Wi-Fi as is and do the occasional reboot. So far everything has stayed connected — no more Samsung TV network errors when I open Netflix or YouTube. Thanks for explaining how the IP address stuff works.
Technician avatar Technician
You’re very welcome — glad we could get your Samsung Smart TV back online.

Summary: To fix a Samsung TV No IP Address problem, power-cycle TV and router, connect to a stable Wi-Fi band, confirm IP auto setting, set a manual IP if needed, check DHCP and reservations on the router, then perform a Network Reset and set reliable DNS. Once that’s done, your TV should stop dropping its IP and streaming apps should stay connected.

If you ever get stuck again — “IP auto setting failed”, “Unable to obtain IP address”, or “Samsung TV cannot connect to network” — you can open a chat with an expert and we’ll walk through the exact menus on your model with you.
Customer
Perfect, thanks. The TV has been working all evening with no drops, and now I know what to check if the No IP address error ever pops up again.

If a friend or family member complains that their Samsung TV has No IP address, keeps showing “IP auto setting failed”, or their Samsung TV Wi-Fi keeps disconnecting during streaming, you can share this checklist — and if you’d like someone to click through Samsung and router settings with you in real time, just start a chat with an expert and we’ll take it from there.

Quick answer: the accepted fix

Accepted fix when a Samsung TV shows “No IP address”: power-cycle TV and router, connect to a stable 2.4 GHz or 5 GHz Wi-Fi, verify IP auto setting, reserve an IP for the TV in the router’s DHCP, then run Network Reset on the Samsung TV and set reliable DNS so streaming apps stay online without dropping the IP.

Why Samsung TVs show “No IP Address” (DHCP, router settings, Wi-Fi issues)

Most Samsung TV No IP address problems come from how the TV and router talk to each other, not from your internet speed. The TV has to request an address from the router’s DHCP server; if that process fails, you see “No IP address”, “IP auto setting failed” or 0.0.0.0 in Network Status.

Glitches in the TV’s Wi-Fi module, buggy firmware, crowded Wi-Fi channels, or strict security (MAC filtering, access control) can all stop your Samsung Smart TV from getting an IP. Separating the path into router with healthy DHCP, a clean Wi-Fi channel, and a TV with fresh network settings usually clears the error and keeps services like Netflix, YouTube and Prime Video connected.

How to tell if “No IP Address” is the Samsung TV or the router

To narrow down a Samsung TV IP address problem, compare it with other devices on the same router. If phones and laptops get normal IP addresses (like 192.168.x.x) while the TV shows 0.0.0.0 or No IP address, the router is likely fine and the TV’s network stack needs a reset or manual configuration.

If multiple devices randomly lose their IP address or cannot obtain one, that points more to a DHCP / router issue. In that case, resetting the router, updating its firmware, and checking DHCP settings is as important as resetting the Samsung TV. Testing the TV briefly on a different network (for example a mobile hotspot or another router) is also a good way to see whether the TV itself can get an IP normally.

Samsung TV No IP Address — quick troubleshooting tips

Reset TV and router, fix DHCP and DNS, then keep Wi-Fi simple and stable.

Fast path: cold-boot your Samsung Smart TV → power-cycle the router → connect to a stable 2.4 GHz or 5 GHz Wi-Fi network → set IP to Obtain automatically → if it still fails, assign a manual IP and DNS → add a DHCP reservation for the TV in the router → run Network Reset on the TV and update firmware so it stops losing its IP during streaming.

FAQ

Why does my Samsung TV say “No IP address” or “IP auto setting failed”?

A Samsung TV No IP address or “IP auto setting failed” message usually means the TV did not receive an IP from the router’s DHCP server. That can be caused by temporary glitches in the TV’s network stack, DHCP problems on the router, Wi-Fi interference, or security features like MAC filtering and access control that block the TV from joining the network.

How do I fix Samsung TV No IP address on Wi-Fi?

First, cold-boot the TV and power-cycle your router, then reconnect the TV to a stable 2.4 GHz or 5 GHz Wi-Fi network. In IP Settings, start with “Obtain automatically”; if that fails, temporarily use a manual IP address with the correct subnet, gateway and DNS. Add a DHCP reservation for the TV in the router, perform a Network Reset on the Samsung TV, and set DNS manually (e.g. 8.8.8.8) to keep the connection stable.

Should I use automatic or manual IP and DNS on my Samsung TV?

For most people, leaving the Samsung TV on automatic IP (DHCP) is best, especially if you create a DHCP reservation for the TV in the router. However, when troubleshooting No IP address or “unable to obtain IP address” errors, manually assigning an IP and DNS can confirm the TV’s Wi-Fi is working and often restores connectivity while you sort out DHCP issues.

When should I replace or reset my router if Samsung TV keeps losing its IP?

If you’ve power-cycled equipment, checked DHCP, added a reservation, updated firmware, and reset the Samsung TV’s network settings but it still shows No IP address while other devices also drop off, your router may be the weak link. In that case, a full factory reset of the router or upgrading to a newer model with reliable Wi-Fi and DHCP can be the best long-term fix.
