The best solution is to bind the Internet and IPTV to the same LAN port of Optical Cat with VLAN, and then divide the Internet and IPTV data into two interfaces with a VLAN switch.

The steps are as follows:

First, log in to the management background of Guang Mao. Different places and different operators have different login addresses and account passwords, so they can search online; 2. Find the uplink configuration, uncheck all ports bound to the Internet connection, and record a part of the VLANID Internet; 3. Uncheck all ports bound by IPTV connection, and record the VLANIDIPTV; 4. In the binding setting, change the binding mode of LAN 1 port to VLAN binding, and bind the two VLAN id just recorded to 2(WAN) and 3 (IPTV) respectively; The VLAN switch is placed under the TV in the living room. Port 1 is connected to LAN 1 in Guang Mao, port 2 is connected to WAN port of router, port 3 is connected to LAN port of router, ports 4, 5, 6 and 7 are connected to computer and wireless AP as required, and port 8 is connected to IPTV set-top box.

With this setting, the problem that Internet and IPTV*** use a single network cable can be solved by adding a VLAN switch.
