I opened this BUG on LEDE bugtracker:
https://bugs.lede-project.org/index.php?do=details&task_id=284
Using git bisect I found out that the revision breaking the WIFI on the WRT1900ACS is:
d15dc7e85dbf38c07dd5a7f8068ee6655830548e
fstools: update to latest git HEAD
adds f2fs support
Anyone who experienced the same issue ?
It looks like that I can put the WIFI down only when reading from the attached HDD USB 3.0
Except the errors reported from the Kernel for the wifi, I can't see anything for the USB.
Anyone know which would have been the change in fstool to potentially lead to this scenario?
