Hello @gopesh03 ,
Welcome to our community.
Here are some suggestions that may help you:
1. Reboot Devices:
Restart both your router and the wired client devices connected to LAN port 2 and 4. Sometimes, a simple reboot can fix connectivity problems.
2. Test with Another Device:
Connect a different device to LAN port 2 and LAN port 4 using the same cables. If these devices still do not receive a network connection, the issue is likely with the router's LAN ports.
3. Check IP Configuration:
Make sure the wired client devices are set to obtain an IP address automatically (DHCP).
For Windows: Go to the Network Connection Details page and confirm that "DHCP enabled" is set to "Yes."
For Mac: Navigate to Network > Advanced and ensure "Configure IPv4" is set to "Using DHCP."
4. Check IPTV/VLAN settings:
Launch a web browser, at the top of the window in the address bar type in https://tplinkwifi.net, and then press Enter.
Go to Advanced>Network>IPTV/VLAN, check if LAN 2 and LAN 4 are selected as IPTV ports.
