I've been trying to get an OpenWrt device (EX6150v2) working as a range extender. I've been having a bunch of problems, but those are for other threads.
Anyway, one of the suggestions to get internet access working was to change the LAN IP address to a different subnet, so I changed the IP from 192.168.1.1 to 192.168.2.1. However, when trying to apply the change, it got stuck on the 'reverting change' screen, so I refreshed the page.
Now I cannot get back in. I've tried both IP addresses to no avail. The connection just times out trying to load the page. Please reply with any help.
