I received my Netgear R7800 router yesterday. I want to install OpenWRT on it tonight.
How do I have to proceed with the installation? Do you have to upload it via TFTP? Does anyone know of any instructions I can follow so that nothing goes wrong? And what would you recommend installing the Stock OpenWRT firmware, or a modified version?
Installing from the OEM firmware should work ok from the Netgear GUI using the "factory" OpenWrt image (not the sysupgrade image).
(The TFTP approach is a fallback option, which may help, if you run later into problems.)
I suggest that you either install the official OpenWrt firmware 21.02.1 (with GUI), or alternatively my community build, where some defaults settings are a bit tailored for R7800 and the image contains some typical add-on packages.
Thank you for the feedback. I'm assuming that I can still install a SysUpdate about your version later, right? Could someone please tell me which version to download here? Which is the most recent and modified version?
