Samsung TV error 105 typically reflects a combination of DNS resolution issues and general network instability, resulting in an internet connection that works inconsistently, loads some content but not others, or drops intermittently throughout use.

What Error 105 Means

Unlike a clean total connection failure, this error usually presents as an unreliable network experience: streaming may buffer excessively, some apps load while others fail, and the connection status may fluctuate between connected and disconnected states without a clear pattern.

Common Causes

Inconsistent DNS server response times, whether from your ISP or router-assigned DNS, are a leading cause of this unstable pattern. Network congestion during peak usage hours, common in Nairobi households where multiple people stream simultaneously in the evening, can cause intermittent failures. An ageing router struggling to handle modern bandwidth demands is another frequent contributor. Firmware instability on the TV following an incomplete or corrupted update can also produce inconsistent network behaviour.

How to Fix It

Switch to a reliable public DNS server such as 8.8.8.8 or 1.1.1.1 through Settings > General > Network > Network Status > IP Settings, which resolves a large share of Samsung TV error 105 cases caused by DNS inconsistency. Restart your router and, if possible, upgrade to a more modern router better suited to handling multiple simultaneous streams. Running the connection during off-peak hours can help confirm whether congestion is a contributing factor. Ensure the TV's firmware is fully up to date, and consider a full network settings reset if instability continues, which clears any corrupted configuration accumulated over time.

Frequently Asked Questions

1. Why does my connection work sometimes but not always? This inconsistent pattern typically points to DNS response instability or network congestion rather than a complete connection failure.
2. Does changing DNS settings really make a difference? Yes, switching to a fast, reliable public DNS server often significantly improves connection consistency.
3. Can too many people streaming at once cause this error? Yes, network congestion during peak hours is a common contributor to unstable connections on shared home networks.
4. Should I consider upgrading my router? If your router is several years old and struggles with multiple devices, an upgrade can meaningfully improve stability.
5. Is this error ever caused by the TV itself? It can be, particularly if firmware is outdated or corrupted, though network-side causes are more common.
