Dir-615 d4 does not save setting in 18.06 but did in 17.01


#1

This is follow up on this: D-Link Dir-615 rev D4 is not saving my settings

I am facing same problem - power cycle resets all the settings. Downgrading to 17.01.6 solves the problem.

BusyBox v1.28.3 () built-in shell (ash)

I also tried removing some packages to get some free space (i removed all ppp stuff) - but after reboot the packages reappear.

You can't remove something that's in the base firmware because that part is read only. The packages will only be marked as deleted in the overlay file system, not actually deleted. Because your overlay file system is on a temporary RAM disk, that marking will be gone after a reboot.

You need to compile your own firmware without the packages you don't need.
See https://openwrt.org/docs/guide-user/additional-software/saving-space


Root full after flashing -> can't save any settings

This router has only 4 MB flash and probably is out of memory with Openwrrt 18


#4

It works now. I've rebuild the image without pppd and ipv6.
Here it is:
openwrt-18.06.1-ramips-rt305x-dir-615-d-squashfs-sysupgrade-less_ppp-less_ipv6.bin
Thanks everyone!
