I just today installed openwrt to my router and am admittedly in over my head. I need some help reverting back to the oem firmware. Please be as descriptive as possible, I am for sure a newbie at networking.
Not sure why you’d want to rollback. Providing the device is fully supported on openwrt, it should be better in so many ways compared with vendor software. Did you want to dicuss the issues your having and try and resolve them?
if you really want to rollback the documentation for your device is pretty good :
Get someone local to help you out. I'd be happy to help if your in Sydney.
