I realise after power on reset it will be reset to factory default. I have wired Eth0 direct to ethernet on the PC which is set to static 192.168.1.2 with mask of 255.255.255.0 and default gateway 192.168.1.1, but the router won't response to pings and I can't bring up to log in screen in the browser with https://192.168.1.1.
Browsing thru forums it seems like it has been reported before., although I am not sure what I did to have triggered it.
