I freshed installed the firmware on the device because it used to be my main router, but this time I want it to work as a “dumb” AP, so I followed the instructions here. After changing the static IP from the default 192.168.1.1 to 10.12.20.50, I tried to login to LuCI but it was impossible.
I deleted the browser’s cache, plugged in the cable to different ports, power cycled the router, but nothing. I have reset the router like 20 times at this point and there’s simply no way I can login to LuCI with the new IP.
I even run an IP scanner and it showed the device with 10.12.20.50, but still couldn’t login. I really don’t understand what’s going on because I’ve done this many times with other routers and never had a problem.
Based on my experience, the IP address cannot be directly modified. You need to add a new IP address first, apply the changes, then log in to delete the old address, and then restart. Otherwise, you'll encounter the problem you've observed—you'll never be able to connect.
You should not need to add a new IP address -- directly changing should work just fine.
The nuance here is two-fold:
when you're changing subnets, it can be hard to reconnect before the device rolls back to the previous subnet
on 25.12, the default IP address also has the CIDR subnet. (i.e. 192.168.1.1/24). When you change the IP address, you need to also include the CIDR subnet, else the device becomes unreachable.
Now, if I'd want to pass it a VLAN? I already set up the VLANs on the main router and got it working with a Omada EAP.
The Archer C60 works with “switch”, not DSA. So what I did was create two VLANs, 20 for access to the router, and 24 for normal traffic. Then, I created a new bridge device with port Ethernet Switch: “eth0”. Finally, I created two new interfaces, one for VLAN 20 and other for VLAN 24, both with protocol Unmanaged and the corresponding devices.
Unfortunately, it didn't work. I also was locked out from LuCI. Could you please help me?
Probably best to start a new thread for this. Feel free to tag me into it. In the new thread, please describe your physical topology and provide the configs from both the main router and the AP.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
I'm just adding this as I followed this guide which effectively locked me out of accessing the router (via SSH or any other method I attempted)...so, in case anyone is in the same boat as me.. I was lucky enough to stumble along LuCI essentials which thankfully I randomly saw "ssh root@openwrt.lan" and decided to risk it for the biscuit.
This worked fantastically well (althougth I typed root@OpenWrt.lan). I was then able to SSH in and follow psherman's solution and able to access the router via browser again.
