Step-by-Step Technical Resolution
1
Log into your router admin panel and separate 2.4GHz and 5GHz into distinct network names (e.g. WiFi_Home_5G).
2
Lock the 5GHz Wi-Fi channel to Channel 36, 40, 44, or 48 (avoiding DFS channels 52-144).

4
Turn OFF 'Energy Saving Mode', 'Ambient Light Detection', and 'Auto Power Off'.
5
Go to Settings > General > Network > Reset Network, then reconnect exclusively to your 5GHz network.

If issues persist, use an Ethernet cable or a USB-to-Ethernet network adapter.
Frequently Asked Questions
Why does my Samsung TV keep losing Wi-Fi when watching IPTV?
Sustained high-bandwidth video causes buffer underruns if your router steers the TV between 2.4GHz and 5GHz frequencies.
Which Wi-Fi band is best for IPTV on Samsung TV?
Always use 5GHz Wi-Fi on a fixed non-DFS channel (36-48) for high bandwidth and zero microwave interference.
Will an Ethernet cable fix Samsung TV Wi-Fi drops?
Yes, a physical wired connection completely bypasses wireless interference and router band steering.
