I would highly recommend to the router with the current firmware 6:05. I was so far satisfied with my 7390 up to WiFi, was here and is the data throughput compared to 7490 are not comparable. Because looking at my family growing smartphone and tablet the way to the Internet, I now had to act, though many have written of problems, I can not find anything serious. Above all, the USB 3.0 has laid proficient at pace! I have my main LAN connections to 1 Gigabit switched, which can only recommend strongly if you like I will send so much data (HD.MKV) on the server! Stream videos and music all works without interference.
Furthermore, I do not want to leave unmentioned, let the switching from their usual settings 7390 or phone book on the safety function to play in large part to the 7490. This saves a lot of work.
The current firmware version is very stable and the router is no longer as hot as its predecessor and also uses less power.
