Monitors Samsung Smart Monitor P28 (models M50/M70 2023–2026 series) combine the features of a display and a smart TV, but their wireless capabilities often go unused. Users encounter difficulties when connecting to Wi-Fi for the first time: the menu grid is unclear, and the instructions lack step-by-step screenshots for a specific model. This article fills this gap—here you'll find Three official ways to activate Wi-Fi (including hidden functions for older firmware T-MSMDEUC-1403.5), as well as solutions to typical errors like “no networks available” or “authentication failed”.
Peculiarity P28 - dual mode of operation: as a PC monitor and as a standalone device Tizen OSThis determines where to look for Wi-Fi settings. We'll cover both scenarios, and also explain why the monitor might not see the 5 GHz network and how to fix it without a factory reset. If you've already tried connecting and received an error, skip the basic steps and proceed directly to diagnostics section.
1. Method: via the monitor's main menu (Smart TV mode)
This is the standard method for those who use Samsung P28 as a standalone device—without a connected PC. The interface is identical to that of a TV. Samsung on Tizen, but with the caveat that there is no physical remote control (you'll have to use the keys on the case or the virtual remote control in the mobile app).
Algorithm of actions:
- 📺 Click the button
Sourceon the bottom panel of the monitor (orMenu, if you have a modification with a joystick). - 🔄 In the menu that opens, select the item
Smart Hub(orHome- depends on the firmware). - ⚙️ Go to
Settings → General → Network → Open network settings. - 📶 Select
Wireless networkand wait for the available access points to be scanned.
If the list of networks is empty, check:
- 🔋 The monitor is connected to a power outlet (the Wi-Fi module is turned off in energy-saving mode).
- 📡 The router is turned on and broadcasting the network in the range
2.4 GHz(by default P28 does not support5 GHzwithout manual adjustment). - 🔒 The MAC address filter is disabled on the router (sometimes it blocks new devices).
⚠️ Attention: If after selecting a network the monitor asks Samsung account password - this is a synchronization error with the servers Samsung AccountSolution: Restart the monitor by holding the button Power within 10 seconds, then try again. Wi-Fi password and account password Samsung - different things!
2. Method: via the monitor menu in the “PC Screen” mode
When P28 connected to the computer via HDMI/USB-C, its menu is simplified, and Wi-Fi options can be hidden deeper. It's important not to confuse the settings here. network connection of the monitor with the network settings of the PC itself - they are independent!
Step-by-step instructions:
- Disconnect the cable from the PC (or switch the signal source to
TVvia buttonSource). - Click
Menuon the monitor body →System → Network. - Select
Network Setup → Wireless. - In the list of networks, find yours and enter the password (use virtual keyboard on the screen).
If the monitor writes "Failed to connect to the network", despite the correct password:
Check the case of your password (Tizen is case sensitive)
Make sure your router is not using WEP encryption (not supported)
Disable the VPN on your router (DHCP is interfering)
Reboot your router and monitor at the same time-->
| Error | Cause | Solution |
|---|---|---|
| "No networks available" | The Wi-Fi module is disabled by software. | Network reset: Settings → Support → Self-diagnosis → Network reset |
| "Authentication failed" | Incompatible encryption (WPA3) | Switch the router to WPA2-PSK in its settings |
| "IP address not received" | DHCP failure on the router | Assign a static IP manually (see section 4) |
3. Method: using a mobile app Samsung SmartThings
If the monitor's physical buttons aren't responding or the on-screen menu is unavailable, use the official app. This applies to owners P28 with newer firmware T-MSMDEUC-1410.1, where remote control support has been added.
Instructions:
- 📱 Install SmartThings from Google Play or App Store.
- 🔍 Turn on Bluetooth on your phone and find the monitor in the list of devices (it should appear as
Samsung M50/M70). - 🔗 Connect to your monitor and select
Management → Network → Wi-Fi Setup. - 🔑 Enter your network password—the app will automatically transmit it to the monitor.
The advantage of this method is automatic range detection (2.4/5 GHz) and support WPA3, which older monitor firmware does not recognize. However, for this to work, the monitor must be included and was within a radius of 5 meters from the phone.
4. Troubleshooting: Why Wi-Fi Won't Turn On
If none of the methods worked, the reasons fall into three categories: hardware (module failure), software (firmware failure) and external (router problems). Let's look at each one.
Hardware malfunctions
Symptoms:
- 🚫 The monitor doesn't respond to pressing
Menu/Source. - 🔌 The Wi-Fi indicator (if present) does not light up when turned on.
- 🔊 When connected via an Ethernet cable, the network works, but Wi-Fi does not.
In this case it is required replacing the Wi-Fi module (detail BCM43455 For P28). Self-repair is not recommended - contact a service center. Samsung with a warranty card (if the monitor is less than 2 years old).
Software glitches
A common issue is the network stack freezing after a firmware update. Solution:
- Do it network reset:
Settings → General → Reset → Reset network settings. - If the monitor is not responding, do full reset (will delete all settings, including accounts): hold
Power15 seconds until reboot. - After the reset, repeat the Wi-Fi setup from scratch.
How to update firmware without internet?
If Wi-Fi isn't working and you need to update your monitor:
1. Download the latest firmware for P28 to a flash drive (file with extension .exe or .zip).
2. Connect the flash drive to the USB port of the monitor.
3. Go to Settings → Support → Software Update → Update Now.
4. Select the firmware file manually.
⚠️ Do not turn off the monitor during the process (it takes 5-10 minutes).
External factors (router)
Check your router settings:
- 📡 Disable the feature
Smart Connect(2.4/5 GHz aggregation) — P28 may not see such a network. - 🔒 Set up encryption
WPA2-PSK(NotWPA3orWEP). - 📊 Change the Wi-Fi channel to a fixed one (e.g.
6or11) - automatic channel selection sometimes fails.
⚠️ Attention: If your router uses mesh network (For example, Google Nest Wi-Fi or TP-Link Deco), monitor Samsung P28 can only connect to the primary node. Try temporarily disabling additional access points.
5. Manually assigning an IP address (if DHCP does not work)
If the monitor receives the error "Failed to obtain IP address" and the router doesn't assign one automatically, assign a static IP manually. This is especially true for networks with strict security rules (for example, in offices).
Instructions:
- In the monitor's network menu, select
IP settings → Manual. - Specify parameters:
IP address:192.168.1.100(For example)Subnet mask:255.255.255.0Gateway:192.168.1.1(your router's IP)DNS:8.8.8.8(Google) or1.1.1.1(Cloudflare)
To avoid conflicts, select an IP address out of DHCP range your router. For example, if the router distributes addresses with 192.168.1.2 By 192.168.1.50, assign to monitor 192.168.1.51.
6. Connecting to a hidden Wi-Fi network
If your router is not broadcasting the network name (SSID), monitor P28 won't be able to find it automatically. In this case:
- In the Wi-Fi menu, select
Add a network manually. - Enter
Network name (SSID)— exactly as it is specified in the router settings (case sensitive!). - Select the security type (
WPA2-PSKin most cases). - Enter the password and save.
- Make sure that in your router settings connection of hidden devices is allowed (option
Allow Hidden SSID Connections). - Try it temporarily enable SSID broadcasting, connect the monitor, and then hide the network again.
If the monitor still does not connect:
7. Alternative ways to connect to the Internet
If Wi-Fi is fundamentally not working, consider the following options:
| Method | Requirements | Restrictions |
|---|---|---|
| Ethernet (cable) | Router with a free LAN port, Cat5e cable | Wired connection, limited mobility |
| USB modem | 4G/5G modem with support RNDIS |
Need a USB-A → USB-C adapter (for P28) |
| Screen Mirroring | Smartphone with Wi-Fi Direct | For screencasting only, no offline internet connection required |
To connect via cable:
- Connect the monitor to the router via the port
LAN(on the back panel P28). - In the network menu, select
Wired network— The IP address will be obtained automatically.
⚠️ Caution: When using USB modem The monitor may not recognize it as a network device. In this case, firmware with support is required. USB Tethering (available for models P28 2026 and newer).
FAQ: Frequently asked questions about Wi-Fi on the Samsung P28
The monitor sees the network but won't connect—it says "Check the password." What should I do?
The problem may be:
- Incorrect letter case in the password (check
Caps Lock). - Special characters in the password (for example,
#or!- try replacing them with letters). - Encryption type (switch the router to
WPA2-PSK).
Also try connecting another device (phone, laptop) to this network - if it has the same problem, reset the router settings.
How do I find the MAC address of a Wi-Fi monitor to connect it to a router?
Go to Settings → General → About Monitor → Network Information. The MAC address will be indicated in the line Wi-Fi MAC (format XX:XX:XX:XX:XX:XX).
If the menu is not available, the MAC address can be found on the sticker on the back of the monitor (look for the line Wireless LAN).
Can the P28 be connected to 5GHz Wi-Fi?
Yes, but with some reservations:
- Models P28 2023 and older support
5 GHzonly after updating the firmware to versionT-MSMDEUC-1410.1or newer. - In manual mode, select the network with the suffix
_5G(if the router broadcasts both ranges). - If 5 GHz is not displayed, check your router settings: the channel must be in the range
36–48(DFC disabled).
After resetting, the monitor doesn't remember Wi-Fi networks. Is this normal?
Yes, factory reset (Settings → General → Reset) deletes all saved networks, including passwords. This is a security measure to prevent the previous owner from connecting to your network.
To avoid having to re-enter your password, use the function Smart Switch in the app SmartThings to transfer settings from another device Samsung.
How to update firmware if Wi-Fi is not working?
There are three options:
- By cable: connect the monitor to the router via Ethernet and update the menu
Settings → Support → Software Update. - Via USB: download the firmware from the website Samsung onto a flash drive and update manually (instructions in Section 4).
- Via SmartThings: If the monitor has ever been connected to Wi-Fi, the app can update it via Bluetooth (firmware no older than 2026 is required).
