Hi all, I've been using ddwrt for a while but now I have a problem and I can't figure out how to solve it. Basically, when a device connects wired, it gets a wrong IP address on a wrong subnet (192.168.0.1) and also wrong a gateway. When a new device connects via WLAN, it works as expected. On my Setup -> Network setup, I have a /24 subnet mask. Also, the DHCP server is running on both LAN & WLAN as set on my Services page. I'm using a Netgear R6400 v1 with DD-WRT v3.0-r54682. Any idea?
Thanks!

This is wrong. It is supposed to be a (bogus, private) domain name not an IP address. For example, home.arpa.
I see nothing that says any clients are getting a 192.168.0.x IP address from your DD-WRT router... and I asked for configuration pages, not status pages.

Sorry about that, I thought to post every single thing that was even slightly applicable. So, no idea about this DHCP issue? I can confirm nothing else is running a DHCP server
it gets a wrong IP address on a wrong subnet (192.168.0.1)
This is not the IP address and subnet of your antenna by any chance?

If this is true, I would configure my VLANs correctly
You have already been given the right information and links in this thread.
You need the settings from the second post / the second example in the thread:

No idea what you are doing wrong, exactly 3 settings are required
I followed your guide and I set the VLANs as you can see in the image attached. Now the DHCP seems to be working, but sometimes it was working too without this change. I'll let you all know if the issue resurfaces again. Thanks!
