    [R7800] Will no longer save settings after reboot.

    If that's the case, then we still need some explanation on why it affects data retention of only a specific partition. Anyway, we need more evidence. A gas torch is the worst tool I can imagine of to heat-up a PCB. It is absolutely possible, that the cold contact is somewhere near the chip...

    [R7800] Will no longer save settings after reboot.

    I think, I now understand, why Netgear and other manufactures continue using NVRAM partitions for keeping the essential settings. The answer is simple: to survive firmware upgrades, otherwise if all the settings are kept as uci configs, users will have to reconfigure or restore settings from...

    [R7800] Will no longer save settings after reboot.

    Hi @kamoj, thanks for welcoming! Somehow missed the first post :) I was confident, the kernel ring buffer size is not enough to keep the early lines! I was wrong) So, just collected the logs, and it appears to be MX30UF1G18AC - Macronix. The second post, yes, I read it. Hope, I can also get some...

    [R7800] Will no longer save settings after reboot.

    Hi everyone. I came across this thread and realized, I can be in this risk group potentially, since my router is manufactured at around 07.2019, but I got it only a month ago brand new. I'm currently using pure stock firmware, and actually, it is still working fine, however, just to be on safe...
