EUREKA!
I finded why netflix wont work and the fix is nidicolous.
After years of working with no one problem my ISP now seem to have problem with PPpoA
With PPpoE all websites works like a charm.
This "bug"/ISP problem is a pain in the ass to find.
Please clarify what you mean by this update? Are you just referring to flashing 19.07.2? Or did you run opkg upgrade on any or all packages after flashing?
Also, regarding this statement -- did you recreate the entire overlay/extroot after installing 19.07.2, or did you simply edit fstab to mount the USB drive (that had been setup as the overlay prior to the 19.07.2 upgrade)?
