I’m trying to setup a dumb AP (openwrt) wired to my existing openwrt. I followed this guide and everything appears to work fine when I plug the AP to LAN 2 of the base openwrt (see diagram).
However, if I connect the AP through port 5 of a switch that sits in between, my entire network seems to go haywire so I’m guessing I’m doing something wrong with my VLAN setup (it was guesswork - I only have basic understanding of VLANs).
Given the setup in the diagram below, how would I go about doing this from scratch?
WAN port of openwrt (base) is connected to Port 1 of the switch.
Port 2, 3 and 4 of the switch are connected to ISP ethernet connections (VLAN 102, 103, 104).
VLAN 110 is being used for the switch's web configuration
Add a wireless (dumb) AP which is connected to port 5 of the switch.
