"Great access speed. Bad or frustrating config ability."3.5 starson by PaKMan21
Pros: Access speed is incredible. Much faster. Seems more reliable than other brands. Less conflict issues with bandwidth or cordless phones since the router also uses 5Ghz bandwidth.
Cons: Advanced users beware. Any changes of router name or IP address and the Cisco Connect software from your pc will not longer work.
Summary: 2 thumbs up for speed. I like the advanced features via the web browser. They (Cisco) need to add the ability to make changes to the guest VLAN via the browser and not the software. Currently it is only supported via the CC software which is just great for novice or beginner users. Frustrating for advanced users who want more control.
Range seems a little better also. I can still get signal in my neighbors basement across the street. In my house the speed without any obstruction is 300 Mbps. Having the router connected in another room and having an AC unit and in wall humidifier between us I'm getting 144 Mbps. I also see 12 other wi-fi networks broadcasting in my area. I'm pretty happy with that.
Making changes to your "guest network" without setting the router name back to default is impossible if you do so. The CC software will not recognize the new router name and will not connect to allow new changes. I couldn't get the browser to prompt for password for guest access after making advanced changes. Cisco support wanted me to rerun the CC software setup utility which wouldn't connect because I made changes to the router.
I'll be looking for firmware updates that incorporate those changes. Once that happens I'd rate the router with higher stars.
