Samsung TV Error 102 — What It Means & How to Fix It

What Does This Error Mean?

Error 102 means your Samsung TV found a Wi-Fi network but could not obtain an IP address from it. The TV needs an IP address from your router to communicate on the network. Restarting the router or assigning the TV a static IP address usually fixes Error 102.

Affected Models

Samsung QLED Q80B
Samsung QLED Q70A
Samsung Crystal UHD AU8000
Samsung The Frame
Samsung Neo QLED QN90B

Common Causes

Router's DHCP server has run out of available IP addresses to assign
Router's DHCP service has crashed or frozen
The TV previously had an IP address conflict with another device
TV's network adapter is not completing the DHCP handshake
Router firmware bug preventing new IP assignments

How to Fix It

Restart your router by unplugging it for 30 seconds and then plugging it back in.

This restarts the DHCP service and clears any frozen IP assignment table.
On the TV, go to Settings > General > Network > Reset Network, then reconnect to Wi-Fi.

This clears the TV's cached network lease and forces a fresh IP request.
Check how many devices are connected to your router and compare to the DHCP pool size.

Many routers default to 50 IP addresses — if more devices are connected, some will fail to get one.
Assign the TV a static IP address via Settings > General > Network > IP Settings > Enter Manually.

Use an IP in your router's range (e.g., 192.168.1.200) and set DNS to 8.8.8.8.
In your router admin panel, expand the DHCP pool size to allow more addresses.

Refer to your router's manual — typically found under LAN > DHCP settings.
Update the TV firmware via Settings > Support > Software Update to fix any known DHCP bugs.

Samsung has released firmware updates addressing DHCP negotiation failures on some models.

When to Call a Professional

Contact your router manufacturer's support if the DHCP service keeps failing. Samsung support can help if Error 102 persists after a full router and TV network reset. A network technician can check DHCP logs and IP address pool settings on your router.

Frequently Asked Questions

What is a DHCP error and why does it cause Samsung TV Error 102?

DHCP is the system your router uses to automatically assign an IP address to each device. Without an IP address, the TV cannot send or receive any data on the network. Error 102 means the TV asked for an address but the router did not respond or ran out of addresses to give.

Will setting a static IP fix Samsung TV Error 102 permanently?

Yes — a static IP bypasses DHCP entirely, so the TV always has a valid address. Make sure to pick an IP address outside your router's DHCP range to avoid conflicts. Write down the static IP in case you need to troubleshoot the network later.

Can too many devices on Wi-Fi cause Error 102?

Yes — if your router's DHCP pool is full, new devices cannot get an IP address. Disconnecting unused devices or expanding the DHCP pool resolves this. A typical home router supports 50–254 simultaneous IP addresses.
