Your TV Samsung Stubbornly refuses to connect to Wi-Fi, even though other devices in the house work fine? This situation is familiar to many Smart TV owners, especially after a firmware update, a new router, or a move. In 80% of cases, the problem can be resolved without calling a technician, but to do so, you need to accurately determine the cause.
In this article we will look at all possible scenarios: from basic checks (like rebooting the router) to hidden TV settings not covered in official instructions. We'll pay special attention to specific models. Samsung QLED, The Frame And Crystal UHD 2020–2026, where the connection algorithm differs from older series. You'll also learn how to bypass router restrictions. WPA3 and what to do if the TV "sees" the network, but cannot obtain an IP address.
We warn you right away: if your Samsung If your device was released before 2018, some methods (such as manual DNS configuration) may not work due to an outdated Wi-Fi module. In this case, you'll need to use alternative connection methods—we'll cover those as well.
1. Basic diagnostics: what to check first
Before digging deep into the settings, make sure the problem isn't hidden on the surface. Here 4 key pointsthat are often overlooked:
- 🔌 Router power supplyUnplug it for 30 seconds, then plug it back in. This will reset the DHCP cache, a common reason why a TV isn't receiving an IP address.
- 📶 Distance to the router: Samsung with module
Wi-Fi 4(Pre-2020 models) lose connection as early as 10 meters from the router if there are walls in the way. Check the signal strength on your smartphone in the same location. - 🔒 Wi-Fi password: Enter it using the TV keyboard, not through the app. SmartThings — sometimes the character case gets confused.
- 🔄 Network mode: If the router is operating in mode
802.11r (Fast Roaming), turn it off - Samsung does not support this standard.
Checking the router is especially important if other devices also started to glitch connection. For example, after updating the router firmware, the MAC address filter may have been enabled or the broadcast channel may have changed. Log into the router's admin panel (usually at 192.168.0.1 or 192.168.1.1) and check:
- 📡 Wi-Fi channelIf it's set to "Auto", try selecting the channel manually.
6or11(they are the least susceptible to interference). - 🔐 Security type: Samsung doesn't work well with
WPA3— switch toWPA2-PSK. - 📱 IP distribution: Make sure the DHCP server is enabled (otherwise the TV will not be assigned an address).
⚠️ Attention: If your router is from a provider (for example, Rostelecom or MTS), some settings may be blocked. In this case, call support and ask them to disable "client isolation" on your Wi-Fi network—this is a common cause of problems with Smart TV.
2. TV settings: hidden connection options
If the basic check doesn't help, it's time to look into the TV's service menus. On models Samsung After 2019, the Wi-Fi connection algorithm changed - it now depends on the firmware version TizenHere's what you need to do:
- Reset network settings: Go to
Settings → General → Network → Network ResetThis will delete all saved passwords and reset DNS settings. - Manual IP entryIf your TV sees the network but won't connect, try setting a static IP. To do this:
- In the Wi-Fi connection menu, select "Advanced".
- Please enter an IP address from your router's range (e.g.
192.168.0.100). - In the field
DNSenter8.8.8.8(Google) or1.1.1.1(Cloudflare).
Settings → Network → IP Settings → IPv6 Settings and select "Disable".On models QLED 2022–2026 There is another trick: if the TV takes a long time to connect, try Disable the "Quick Connect" feature in the Wi-Fi settings. It speeds up the connection, but sometimes leads to interruptions.
☑️ Checking Samsung TV settings
If after these manipulations the TV still does not connect, check regional settingsIn some countries (for example, in Europe) Samsung blocks connections to open networks or networks with non-standard characters in their names. Go to Settings → General → Language and Region and select "Russia" or "USA".
3. Firmware issues: updating and downgrading
One of the most insidious bugs is when the TV stops connecting to Wi-Fi after automatic firmware updateThis is typical for models Crystal UHD 2020–2021, where in versions Tizen 5.5–6.0 There was a bug with the Wi-Fi module driver. This is how it's fixed:

Settings → Support → About TVIf the firmware version is older16xx(For example,1603.5), it needs to be updated. - Forced update:
- Connect your TV to your router via Ethernet cable (yes, even if Wi-Fi is not working).
- Go to
Settings → Support → Software Update → Update Now. - If the update is not found, download it manually from the website. Samsung (specify the exact model!) and download via USB.
- Download the required firmware from the forum SamMobile (search by TV model).
- Unzip the archive and copy the file to the flash drive in the following format:
FAT32. - Insert the flash drive into the TV, go to
Settings → Support → Software Update → Update Now— the system will find the rollback file itself. - Unplug the TV from the power outlet.
- Press and hold the button on the remote control
Enter (OK)and, without letting go, turn on the TV. - Hold the button for 10-15 seconds until the recovery menu appears.

| Channel width | 20/40 MHz (car) |
Width 80 MHz may cause interference, especially in multi-apartment buildings. |
| Security type | WPA2-PSK (AES) |
WPA3 And TKIP are not supported by the majority Samsung TV. |
| MAC address filtering | Disabled | The TV may not be included in the "white list" of devices. |
| Client Isolation (AP Isolation) | Disabled | Blocks the interaction of devices on the local network, which interferes Smart TV receive IP. |
If your router supports guest network, try connecting your TV to it. Sometimes the main network is overloaded by firewall rules or ISP restrictions. Also, check if the router's firewall is enabled. parental control - it can block access Samsung TV to the Internet by default.
For routers TP-Link, ASUS And Keenetic There is one more trick: turn off the function Band Steering (automatic switching between 2.4 and 5 GHz). TVs Samsung often "get lost" when switching between frequencies, especially if the 5 GHz signal is weak.
