Well I managed to borrow a WLAN device that’s on the Synology approved list.
With the 4.2 it was horrible to Work with. It seemed that the buffer on the USB ran out of memory all the time or something.
I then decided to install the 4.3 update 4 on the N40L. All is fine except that the N40L now don’t want to recognize any USB devices when in Synology.
Anyone got the same problem?
