[cpe1](192.168.1.1), AP Test 1
[cpe1](192.168.2.1), AP Test 2
All working (each on it's own DHCP server) for itself, all good at this very moment.
My plan was then to first get cpe1 working as dumb AP, for this I mapped the wan-port to the lan bridge and disabled then wan&wan6 interface. Then I followed the steps in the wiki.
I tried a coupe of times but the setting for the lan interface always got reset (static ip, gateway+dns on 0.1 and disabled dhcp were not saved). Now, the very last time I tried it looks it was not reverted - but it also doesn't work. I can't even access the web ui (the AP Test 1 is still present and I can connect) anymore and the cpe1 is actually adverting the gateway and dns from cpe (192.168.2.1).
I'm not sure what went wrong and how to fix this mess. I would appreciate any help, specially if it would involve not to touch the devices itself (fixed on a pole couple of meters high in the rain and only accessible with a old, wet wooden ladder at this moment )
This got reverted 3 or 4 times (the disabled startup of firewall, dnsmasq and odhcpd was kept) till I'm in this "soft bricked" kind of mode now. I can't access the web ui nor the ssh from cpe1 anymore.
I can access the openwrt web ui from cpe2 when I'm connected to the cpe1 wifi (AP Test 1) which is now serving gateway and dns from the cpe2 (192.168.2.1)...
Something went clearly wrong and I'm not sure how I can fix this wireless
When you change the LAN IP and hit the Apply the device loses connectivity to the browser. That is why the countdown goes to zero and changes are reverted. You can force apply the changes, after the first failure, or use uci commands, or directly edit the configuration files
For now I need to get access back to my device. Is there by chance any hard coded (fallback IP) available in openwrt the device could react on?
The bad thing about resetting it (should be possible using the poe injector if I understand) is that I need to climb up and getting the device dismounted because it is connected via it's wan-port to my local network. The second cpe(2) actually is connected to the lan jack of the cpe1 but as soon I reset it poe passthrough will be disabled and therfor cpe2 will not be powered anymore...
It's a big mess...
Would be so nice if openwrt could not only be reset but also forced to open a wifi ap..
I only could disconnect the cable between the router and the first (not accessible) cpe1. The interconnection between cpe1 and cpe1 is still present, it's needed to power the second unit (and I also would need to climb to disconnect it). Still it's possible to access the cpe2 using it's wifi ap.
After some search I where able to find a dhpcv6 lease on the cpe2 which I think could belong to the cpe1. Sadly I was not able to ping/traceroute/ssh... it successfully.
I also changed the wan interface on the cpe2 to a static one and set the gateway to 192.168.1.1 as it is connected to the cpe1 and this was it's former IP. No luck here too...
If you have more ideas to recover the device - without resetting/physically accessing it - I'm happy to hear them
Could you give me just a little hint for the initial lan-port config, default looks like this:
I actually need to have both of the lan ports in the lan bridge (so no wan port at all) to be able to daisy chain them. I tried now a couple of ways but the configuration never succeeded.
Most obvious was to just add the eth0.2 interface to the lan bridge (br-lan) but I think it conflicts with the present wan interfaces. I also deleted them on one try and on another I added the wan interfaces to the lan firewall group. No luck for me, always reverts the settings and I'm back on the default setup.
