TP-link does not discover switch
I have fiber to the home. The ISP Ethernet carries IPTV on VLAN ID 4 and Internet.
I configured the Switch as follows:
Port 1 : VLAN ID 2 (untagged) Connected to : Internet Service Provider
VLAN ID 4 (Tagged)
Port 2: VLAN ID 2 (untagged) Connected to Router WAN Side
Port 3 till 6
VLAN ID 4 (untagged) Connected to IPTV Setup Boxes.
Port 7-16
VLAN ID 1 (untagged)
Port 9-14 and 16
VLAN ID 100 (untagged)
Port 15 VLAN ID 100 Connected to Router LAN side
When port 1 is not connected to the ISP the I can manage the switch with the "Easy Smart Configuration Utility" but as soon as I connect port 1 to the ISP then I can not manage the switch and the utility does not see the switch as well.
By setting the ISP WAN side to VLAN ID = 2, I assumed that it would not involve VLAN ID =1.
Every thing works fine, The setup boxes for IPTV working fine and the internet works fine as well, only I can not login to the switch and monitor the switch and or do some changes.
What I'm doing wrong? Or should I use another smart switch to extract VLAN ID = 4 from the ISP?
