I can confirm that this version is not recognizing some devices, specifically two xbox ones on the same router.
My xbox #1 is seen as Unknown Device at the on set of setting up the router with just one wired LAN PC connected to the router and both xboxes connected via LAN cable as well. xbox #2 is detected as Microsoft.
This issue was also reported by BIPOLAR BEAR in a private chat. I've asked him to follow up here as well with his information. I've pass this onto D-Link for review as well.
Also getting OPEN NAT in Game is not possible with the 890L as it seems that either uPnP and or QoS can't correctly open a virtual port for a 2nd game console and allow the game to get a OPEN NAT status. I can do this with older DIR/DGL series routers and a non Mfr'd D-Link router.
I'll post more info here of testing I did last nite:
