cannot connect to pi ip.

after no success with 2 weeks of attempted calibration and vaoc led stopped working i thought id start again. Flash sd card. Now not connecting via ethernet ip. Can only connect to pi via ratos.local network. Thus no internet and no updates and no config. Tried 3 x diff sd cards. Put old install sd card back in and works. Tried diff raspi still no go. WTF is wrong with this stupid thing? :need: Cheers.
