The situation when smart TV A smartphone refusing to connect to the internet via a hotspot is a fairly common and confusing issue. The logic seems simple: the phone receives mobile internet and distributes it, and the TV should see this network like a regular home router. However, in practice, users often encounter problems with the device simply not seeing the network, or the connection being lost immediately after entering the password. This is due to the specific architecture of mobile networks and the specific connection stability requirements of Smart TVs.
The main problem is that mobile hotspot works differently than a desktop router. A smartphone doesn't always correctly process requests from multimedia devices attempting to connect to update servers or streaming services. Additionally, there are technical limitations on the number of devices that can be connected and the devices used. encryption protocols, which can block attempts to authorize the TV. Understanding these nuances is the first step to successful setup.
In most cases, the solution lies in changing the frequency band settings or resetting the network parameters. You don't need to be a network expert to fix the error. Simply check the access point configuration on your phone and the network settings on your TV to rule out software conflicts.
Incompatibility between the 2.4 GHz and 5 GHz frequency bands
One of the most common reasons why TV If the phone doesn't see the network, there's a frequency band mismatch. Modern smartphones often create an access point in the range by default. 5 GHz, as it provides higher data transfer speeds. However, many TV models, especially those released more than 3-4 years ago, are equipped with Wi-Fi modules that operate exclusively in the range 2.4 GHzIf your TV is "old school", it will physically not be able to detect the 5 GHz network.
To fix this, you need to go to the hotspot settings on your smartphone. Depending on the model (Android or iOS), there may be an option called "AP Band" or "Use 5 GHz Band". It needs to be switched to 2.4 GHzAfter this, the phone will restart the access point, and it will become visible to a wider range of devices.
It's also worth keeping in mind that even if your TV supports both bands, it may still be stuck on the old network profile. If you've changed the frequency and the TV still won't connect, try forgetting the network on the TV and then re-searching for it. This will force the device to re-run the handshake with the correct parameters.
Issues with security type and encryption
Connection security is a priority for mobile operating systems, but sometimes overprotection becomes a barrier. Smartphones can offer or force a security type. WPA3, which is the latest standard. Many TVs, even those with Smart TV support, still use older Wi-Fi modules that are only compatible with WPA2-PSKWhen attempting to connect to a WPA3 network, the TV may simply silently ignore the request or return an authorization error.
In your phone's hotspot settings, look for the "Security Type" or "Encryption" option. Make sure it's selected. WPA2-Personal or WPA2-PSKAvoid using an open network (without a password), as some TV operating systems (such as Tizen or WebOS) may block connections to unsecured access points for security reasons.
⚠️ Please note: Some telecom operators block or limit tethering on plans with unlimited internet. If your TV connects but your internet connection doesn't work, check your plan's terms with your operator.
Another consideration is the length and characters in the password. If you use complex passwords with special characters, make sure the TV keypad can enter them correctly. Sometimes it's easier to temporarily set a simple 8-digit numeric password to test the connection, and then make it more complex.
Limitations on the number of connected devices
Mobile operating systems have built-in limits on the number of clients that can connect to a hotspot. Typically, this limit is between 5 and 10 devices. If your phone is already connected to a tablet, laptop, or smartwatch, your TV may simply not receive an IP address due to the DHCP address pool being full.
In addition, channel bandwidth is important. Mobile Internet has a limited data transmission channelIf one of the connected devices starts downloading updates or watching 4K video, the TV may not have enough resources to establish the initial handshake with the server. This creates the illusion that the Wi-Fi is down, when in fact the problem is channel congestion.
It's recommended to disconnect all unnecessary devices from the access point before attempting to connect to the TV. This will free up your smartphone's processor resources and bandwidth. Also, check your phone settings to make sure there aren't any data restrictions for background apps, which could block TV service requests.
IP address conflicts and DNS settings
Often, the problem lies not in the physical connection, but in a logical error in address allocation. When the TV connects to the phone, it requests an IP address via DHCP. If the router's (in this case, the phone's) cache is corrupted, the TV may receive an address that's already taken, or not receive one at all. In this case, the connection status will remain "Obtaining IP address."
To solve this problem, you can try manually entering static network settings on your TV. You'll need to find out your access point details (usually the gateway is the IP address of your phone, often 192.168.43.1 or 192.168.1.1). In the TV network settings, select "IP Settings" -> "Enter Manually".
Pay special attention to the servers DNSMobile operators often provide their own DNS, which can slow down or block Smart TV requests. Try setting up public DNS from Google or Cloudflare. This often solves the problem when Wi-Fi is connected but apps won't load.
| Parameter | Value for manual input | Description |
|---|---|---|
| IP address | 192.168.43.150 | Unique address in the phone subnet |
| Subnet mask | 255.255.255.0 | Standard mask for home networks |
| Gateway | 192.168.43.1 | Your smartphone's IP address |
| DNS 1 | 8.8.8.8 | Google's primary DNS |
| DNS 2 | 1.1.1.1 | Cloudflare Alternative DNS |
Power saving and sleep mode for your smartphone
Modern smartphones aggressively optimize power consumption. Sharing internet via Wi-Fi puts a heavy load on the radio module and processor, causing overheating and rapid battery drain. In response, the system may automatically disable the hotspot or limit its functionality if the phone's screen goes dark or if a running app is left in the background.
If the TV disconnects from the network after a few minutes of operation, most likely the energy saving timer is activated. Android On your devices, find the "Access Point Timeout" setting and set it to "No Timeout" or "Always On." You should also add the "Access Point" app to the power saving mode exceptions.
On iOS The situation is similar: if you minimize the app or lock the screen, the data connection may stop after a while. To avoid this, keep your phone's screen on during setup or use the special "Tethering" settings.
Why does my phone get hot when using Wi-Fi?
Wi-Fi sharing uses the radio frequency module at maximum power, especially if the mobile network signal (3G/4G) is weak. The phone is forced to constantly search for a base station and broadcast a signal, which causes the battery and processor to heat up. This is normal, but it can lead to throttling (a decrease in speed).
Network service and Wi-Fi driver failures
Sometimes the problem is software-related and involves network table overflows or errors in the wireless module drivers. This can occur on both the TV and the phone. Complex network protocols, used for Smart TV (such as DLNA or AirPlay), may conflict with regular access point traffic.
The first thing you need to do is perform a full reset of your network settings. On a TV, this is usually done through the menu. Settings → General → Network → Network ResetOn your phone, simply turn airplane mode off and on again, which will reboot the radio module.
If this doesn't help, try changing the access point name (SSID). Some TVs cache network settings by name. By changing the name from "iPhone" to "MyTV_Hotspot," you'll trick the TV into thinking it's a completely new network and will apply the new connection settings.

Alternative ways to distribute Internet
If a standard Wi-Fi hotspot absolutely doesn't work, there are workarounds. The most reliable of these is using a USB modem. Many modern TVs based on Android TV or Linux Support connecting a smartphone via a USB cable. In this case, the phone is detected as an Ethernet adapter, providing a more stable connection and simultaneously charging the device.
To do this, enable "USB tethering" mode on your phone (usually found in the same settings as the hotspot). Connect your phone to the TV using a cable. The TV should automatically switch to a wired connection, ignoring any issues with the Wi-Fi module. This also resolves issues with the frequency range and encryption.
Another option is to use third-party routers or travel routers that can receive Wi-Fi from your phone and broadcast it to your TV, acting as an intermediary. These devices often have more powerful antennas and are better at handling client reconnections.
⚠️ Important: When using a USB connection, make sure the cable supports data transfer, not just charging. Cheap "charge-only" cables will not transmit an internet signal.
Frequently Asked Questions (FAQ)
Why does the TV say "Connected, no internet access"?
This means there's a physical connection between the TV and the phone, but the phone isn't transmitting data. Check if the internet is working on the phone itself (by disabling Wi-Fi). The issue could also be due to incorrect DNS addresses or traffic being blocked by your carrier.
Is it possible to share the Internet via Bluetooth if Wi-Fi is not working?
Technically, this is possible (Bluetooth PAN mode), but the connection speed will be extremely low (no more than 1-2 Mbps). HD video will constantly buffer. This method is only suitable for text updates or downloading lightweight apps.
Does internet tethering affect the quality of mobile communications?
Yes, when actively using a hotspot, your phone operates in enhanced data transfer mode, which can cause the device to heat up and drain the battery faster. Voice quality may also be temporarily reduced in areas with poor reception.
How to increase internet speed on TV via phone?
Move your phone closer to a window or a cellular signal source. Make sure you're using the 5 GHz band (if your TV supports it), and close any background apps on your phone that are consuming data.
