Samsung TV Error Code 105: Mobile Hotspot Troubleshooting... | digitalhomefaults.org

Technical Background:

Samsung TVs utilize Wi-Fi (2.4GHz/5GHz) to connect to the internet via a router or mobile hotspot. Error Code 105 signifies a failure in establishing or maintaining this connection. The TV attempts to acquire an IP address from the hotspot's DHCP server. Packet loss or DHCP lease failures can trigger this error. Power consumption profiles fluctuate based on Wi-Fi signal strength and data transfer rates.

Symptoms:

Error Code 105 typically presents as a network connection failure. The TV's network status indicator shows a disconnection from the internet, despite the mobile hotspot appearing to be active. App-side error logs within the Samsung SmartThings app may mirror this disconnection.

Possible Causes:

Weak Wi-Fi signal strength (RSSI < -70dBm) from the mobile hotspot.
Incompatible Wi-Fi security protocol (e.g., WEP instead of WPA2/WPA3).
Mobile hotspot data limits or throttling imposed by the Canadian mobile carrier (Bell, Rogers, Telus).
Interference from other electronic devices operating on the 2.4GHz band (microwaves, cordless phones).
DHCP lease time exhaustion on the mobile hotspot without renewal.
Firewall or port blocking on the mobile hotspot preventing TV access.

Solution:

1

Verify mobile hotspot signal strength: Ensure the TV is within close proximity (ideally < 5 meters) of the mobile hotspot. Use a Wi-Fi analyzer app (e.g., Wi-Fi Analyzer) on a smartphone to measure the RSSI. A value of -60dBm or higher is recommended.
2

Check Wi-Fi security protocol: Access the mobile hotspot's settings via its configuration interface (usually a web browser). Confirm that WPA2 or WPA3 security is enabled. WEP is outdated and less secure.
3

Restart both the Samsung TV and the mobile hotspot: Power cycle both devices by unplugging them from the electrical outlet for 30 seconds.
4

Manually configure the TV's IP address: In the TV's network settings, switch from DHCP to static IP. Assign an IP address within the mobile hotspot's subnet (e.g., 192.168.43.50), a subnet mask of 255.255.255.0, a gateway of 192.168.43.1 (typically the hotspot's address), and a DNS server of 8.8.8.8 (Google's public DNS).
5

Update the Samsung TV's firmware: Navigate to the TV's settings menu and check for available software updates (OTA). Ensure the TV is connected to a stable network during the update process.
6

Reset the TV's network settings: If the issue persists, perform a network reset within the TV's settings menu. This will clear any saved Wi-Fi passwords and network configurations.
7

Check Mobile Hotspot APN: On Bell/Rogers ensure the APN (Access Point Name) is set correctly. Consult your provider's website for the most up to date information.

Safety Warning:

Never attempt to disassemble or repair the Samsung TV or mobile hotspot yourself. High voltage components are present inside the TV. Ensure the TV is properly grounded and that all electrical connections are secure. Do not expose the TV or mobile hotspot to excessive moisture or extreme temperatures (<-40°C).

Prevention:

- Regularly check the mobile hotspot's data usage and ensure it is within the allocated plan limits. - Position the mobile hotspot in a central location to maximize Wi-Fi coverage. - Schedule periodic firmware updates for both the Samsung TV and the mobile hotspot. - Avoid using the mobile hotspot in areas with high levels of electromagnetic interference. - Monitor the battery health of the mobile hotspot device and replace it if necessary.

Expert Tip:

If the TV consistently fails to connect to the mobile hotspot, try using a different mobile device or Wi-Fi router as a temporary hotspot to isolate the issue. You can also try changing the hotspot's channel to one that's less congested (channels 1, 6, or 11 on 2.4 GHz are usually best).

Frequently Asked Questions

•How do I find my Samsung TV's IP address?

Navigate to Settings > General > Network > Network Status. The IP address will be displayed along with other network information.

•Why is my Samsung TV constantly disconnecting from Wi-Fi?

Possible causes include weak Wi-Fi signal, interference from other devices, outdated firmware, or incorrect network settings. Troubleshoot each of these factors to identify the root cause.

•Can I use a VPN on my Samsung TV when connected to a mobile hotspot?

Yes, but you will likely need to configure the VPN on the mobile hotspot device itself, as most Samsung TVs do not have native VPN support.
