Identify the television delivery arrangement
Record whether you use an internet provider's managed set-top box or a separate player with an authorized service source. Those can have different network requirements. The same word IPTV does not make their configurations interchangeable.
A channel logo, paid term or player icon does not establish a VLAN ID or port assignment. Obtain those values only from the actual provider and model documentation. Do not copy numbers from another country or another customer's screenshot.
Check what the setting changes
Official TP-Link guidance shows that relevant IPTV/VLAN features can assign particular LAN ports for an ISP television role. Other equipment plugged into such a port may not have ordinary internet access under that arrangement. Exact behaviour depends on the model and configuration.
That means enabling a feature can change the television's network path rather than simply prioritize its video. Keep the previous setting and port role privately before any supported change. Shared provider telephone or other services may also need consideration.
Diagnose a change-related failure
If ordinary internet access disappeared after a documented port-role change, record that timeline. Compare the device through a known intended ordinary LAN path where safe and authorized. Do not change the service password while the local port no longer provides its expected connectivity.
An illustrative standalone player can work on a normal internet LAN connection while failing on a port reserved for another provider receiver arrangement. That is a topology/configuration question. It does not establish that the player is unlicensed or that another subscription must be purchased.
Restore or implement the supported design
Have the network administrator reconcile the setting with the exact provider requirements. Preserve a recovery route and avoid changing VLAN, bridge and firewall settings together. If the feature is genuinely needed for a managed receiver, follow that documented design rather than disabling it blindly.
After the correction, verify ordinary access for affected devices and the original permitted programme. Keep the actual final port roles in a non-sensitive note. The useful outcome is the right network service on the right port, with a marketing label kept separate from an application requirement.

Does the word IPTV on my subscription prove the router's IPTV checkbox is required?
No. The actual delivery method, provider requirements and router feature need to match.
