TP Link, can you check my VLAN configurations on my SG1108E switch, they are in the picture below.  I have a FW/Router connected to a TP-Link TL-SG108E on port 1, on port 2 I have a TP-Link TL-WA3001 AP running in Multi-SSID mode. VLANS are setup on the FWP as VLAN 11 - Main, VLAN 33 - Guest , VLAN 55 - Work, VLAN 77 – MoCA, VLAN 88 - IoT. The VLANS are setup on TL-SG108E the same, VLANS 11, 33, and 88 are tagged on Port 1 and Port 2, and VLAN 55 is tagged on Port 1 and Untagged on Port 8 and VLAN 77 is tagged on Port 1 and Untagged on Port 5. The last 2 go directly to a PC for work and a MoCA device for the cable TV. When I am on a wireless connection I cannot connect to devices across VLANS, for example a phone on VLAN 11 to a Chromecast on VLAN 88.
