Diagnostic steps for DD-WRT setup
Diagnostic steps for DD-WRT setup
You followed the setup steps correctly for client mode but encountered an issue connecting to the main AP. The problem likely lies in the network configuration or SSID settings on the DD-WRT device itself. Double-check that the AP is properly configured and that the SSID matches what you expect. Also verify that the DHCP settings are working as intended.
The default gateway should point to the DD-WRT firmware itself rather than the internet-accessing AP. The DHCP pool setting refers to assigning IP addresses dynamically, not a static DNS configuration. You won’t find a direct option named "DNS Pool" for that purpose.
The default gateway needs to be the same network host that understands routes for other networks, since it’s directly linked to another network. For your dd-wrt connected to the main AP, that would be the AP’s gateway for that interface. On your hosts inside the dd-wrt, it should point back to the dd-wrt itself. If your AP is already set up with the right gateway, it will reach the internet properly. The dd-wrt with its two interfaces—one toward the main AP and another facing internal DD hosts—should function well. Make sure the main AP has the correct gateway configured, otherwise it won’t connect to the internet, and the dd-wrt connected to the AP should work as expected.
Sure, I understand. Since it's linked to the AP in client mode, disabling the WAN would indeed stop the wireless interface from connecting to the AP as WAN, which would likely cut off your internet connection.
I never configured a dd-wrt so I don't know what specific settings to look for, btw yes it should it's just like a Linux host with a wireless interface connected to the main AP called wlan0, which will have the IP address and gateway configured like a normal host, then it has another interface, called eth0 where you connect, with another IP address range, and since the dd-wrt is already connected to the main AP it will see that interface as "directly connected" so will make the route for another network (first the main AP, then the internet) just make sure the gateway is configured as dd-wrt for clients connecting from eth0
