About a month ago, I set up OpenWRT on a Linksys WRT3200ACM, and wanted a network switch. Seeing that it was listed on the table of hardware, I got a Netgear GS108Tv3 and flashed the image from the table of hardware to it, using the OEM webui to upload the .bin file.
But to my surprise, I couldn't access luci from it. Rereading the table of hardware page, it mentions
OpenWrt configures the switch by default with a management VLAN ID 100 on the LAN, so be sure to set up your client with VLAN 100 to be able to connect to the switch.
So on my wrt3200, I set port 3 (a spare pc) to untagged and port 4 (the gs108t) to tagged for VLAN 100, but couldn't access the gs108t using the dhcp address given from the wrt3200 with either the web interface or ssh. Could my unit be damaged or is something I'm doing wrong?
I've also attempted setting the VLAN to 100 in windows 10 and linux and not being able to connect to the switch, either from the router or directly plugged into it (tried 192.168.1.1 when directly plugged as well). Here is an illustration, the router does have a functioning openwrt flashed, and in all cases the switch does provide an internet connection.
To reiterate, my issue is not being able to access the luci webui for a freshly flashed network switch, and attempted to follow guidance to use VLAN100 to no avail.
