My Archer D9 arrived from the homepage deal from a few days ago. Performance-wise it seems excellent.
I play PC games a lot so one of the first things I did when I got the device this morning was try to setup port forwarding for all the games I host when I play with friends. Before today I've been using a BoB2 from iinet and port forwarding has been a breeze. After failing for a few hours with the D9 I called TP-Link technical support and they didn't seem to find anything wrong with my configuration. I'm currently waiting on them to send a reply to an e-mail I sent that had extra details.
Has anyone actually successfully port forwarded with this device? I feel like I may have just wasted $200.
