I’ve got an hAP-ac being used as a wireless access point and switch behind a RB4011 gateway router. The 16 MB of flash memory is 98% full, and I haven’t been able to upgrade RouterOS due to the low memory. If I add up all of the files in the “Files” listing it comes to less than a megabyte. I’ve got a 16GB USB memory stick installed, but the system apparently doesn’t see that for RouterOS upgrades. There’s really nothing critical in the built-in flash memory. How do I free up space on the built-in disk?
netinstall
