I recently received my router and my initial reaction is "why all the complaints?"... I setup the router, loaded the latest beta firmware and did a factory reset. Then I began to setup my devices and reserved there ip addresses. Overall the wireless has been very stable, coming from the dgl 4500, it does not drop in speeds like its predecessor did. Speed test show a constant stable speed.... The stream boost does work well, it identifys everything well, with one exception, xbox 1 traffic is classified as general and bit torrent. That was the only disappointing thing I have encountered, and hopefully dlink/qolcomm know about this issue and update soon (it does not take the quality of playing away but it would be nice to have it classified the right way, I mean it is a 'gaming router' after all)....
The UI is fine, idk why people are against it. I had the 413 error but did a system reboot and it worked fine afterwords, nothing major.
Again I am happy I bought this and can justify a 80$ price tag easily...
