Already fixed?
I followed the link from this article to the bug description page at Netgear to the update page for my R6300v2 router, only to find that it says this bug was apparently fixed already in the firmware update I installed at the end of December (V1.0.4.6_10.0.76). I see that the bug report numbers are dated 2017, so how is it that they were supposedly already fixed in earlier firmware?
