[Q]: I have had this for several months. The dual WAN feature, which is necessary for me, has become less stable with each firmware update. I have now replaced this with the UTT AC750W. If you need dual WAN, don't get this router or any other ASUS running this firmware. The UTT AC750W is flawless. If you don't care about load balancing multiple WAN connections, then you'll probably be ok.
[A]: Flawed

[Q]: This came right away with prime and I used in place of my desk phone at work. I am on then one all day and I love inline controls and the audio was great. I would buy this again, next I will probably purchase a Bluetooth version for mobility in the office.
[A]: great product, love it

[Q]: My Internet gateway is in my downstairs home office and TV, streamer etc. are in living room upstairs. Signal was horrible for last 3 years. Tried WIFI extender even then signal was weak. Finally read a review about this product and powerline networking in general. Once I got the shipment through Amazon, I installed one end into the power socket, connected ethernet cable to gateway router and the other unit upstairs. Extended ethernet cable to a 100Mbps ethernet switch for TV and streamer. Since it has WIFI I was skeptical it would even work. I got a solid green light on the power line connection and a solid 130Mbps WIFI connection. It just worked. My house is 1200Sq ft, two floors. Just follow the supplied installation guide. You can't go wrong.
