RB751 instable and "hangs"

Hi, i have lot of routerboards - ie RB493G RG750 RB1200 - and they all work like expected…

:frowning: BUT i have lots of trouble with the 751G.
They work for a while - and then they are dead.

Now after my 2 weeks holiday 4 of them are dead.

Some weeks ago some of them seem to work (for a while) after a RESET to factory-default (NETINSTALL)

Has anyone a hint? I like the price and the design and mostly use them as a managed AP.

Thanks

Oliver

Try NetInstall ROS 5.18 or 5.19. Latest RB-s has SAMSUNG NAND Flash K9F1608UOC onboard. At least ROS 5.18 changelog states that problematic NAND flash corruption fixed.
