I misconfigured network settings as a result I am unable to connect into Openwrt using ssh.
Is there a way to hard reset the router modem. Router itself has no reset button and connecting via WLan does snot help either.
Is there a way to reflash/reset openwrt and start over again?
AnythingI have looped upon there did not help me:
The reason why I failed to connect is, because I misconfigured the /etc/config/network as an attemp to set up the router as a device in my lan with static IP.
Repeatedly pressing any button repeatedly during early boot 'should' get you into the recovery mode. If that fails, you can also reflash OpenWrt from AVM's bootloader (ADAM2) via ftp, just like you did initially.
