I had my internet up and running with this router in minutes. It was not simply plug and play, but I believe that is par for the course with cable internet service. I plugged all the cables in, and there was no internet connection. I simply then went through the guided setup available through the router's administration portal and I was all set. We noticed a big difference with our wireless network speed and reach after hooking this router up. Previously, we had trouble streaming high quality videos on our iPads from the other side of the house. After setting this router up, we have no problems. This could be due our old router being just old and slow. But I also used the dual-band feature, and have our iPads connected to the 5 ghz network. I think that we noticed the improvement because we are getting less interference from cell phones and baby monitors. We also have the 2.4 GHZ network running for devices that are not 5 GHZ capable (my cell phone, for example). Altogether, I'm very pleased with this router and would recommend to others. 

Question: How is the configuration?
Answer: setting this router up , we have no problems
