I have an Edimax EW-7478APC router on which I'm trying to install OpenWRT. I followed this wiki (https://openwrt.org/toh/edimax/ew-7478apc) and installed OpenWRT v22.03.2 through the OEM GUI. The upgrade process went without errors and the router restarted. After coming back online, the following happened:
- Wifi 2.4/5 Ghz: Off
- ISP connection to WAN port: Nothing happens
- Laptop to LAN: No DHCP. Tried setting manual to 192.168.1.1 - 1.2 - 2.1 - 0.1 without success. ssh also not working.
Then I tried to plug my ISP into one of the LAN ports and suddenly got DHCP on my laptop from the main ISP router. This leads me to believe that the router is acting as a dumb switch.
Is there a way to prevent it from defaulting to a switch after installation? As switches don't have IPs, I will not be able to access it to change configuration.
I'm able to re-flash the OEM firmware through tftp.
