"stable, USB 3.0 is Fast!, dual bands work well together"4.5 starson by dlpanak
Pros: *rock stable for 9 connected devices in home network
*both 2.4GHz and 5.0GHz work well with excellent speed and balance
*USB 3.0 is FAST!
*extensive menus and configuration options
*HDTV movies streamed with glitches
Cons: *onboard clock is glitchy (without NTP server enabled)
*every change requested a router re-boot, taking 60sec minimum.
*5.0GHz range not quite as good as 2.4GHz range
*a little pricey (>$200)
Summary: I upgraded from a dir-655, which had worked very well since the latest firmware upgrade a year ago. The dual band architecture of the DIR-857 looked interesting(i had been running two d-link routers; one at 802.11n, and one at 802.11a/b/g).i meant *HDTV movies streamed withOUT glitches!
For nine connected devices (one at 5.0GHz-n and the rest at 2.4GHz-n and -g), the onboard wireless status monitor shows connections speeds ranging from 54M to 144M. For the 5.0GHz-n device, switching to 2.4GHz-n would show increase the displayed signal strengh.
A connected WD 2TB USB3.0 drive functioned very well for file backups - surprisingly fast compared to USB2.0
I did experience some glitches withthe onboard cloack - it would loose time with every re-boot and for some reason would always change by 1 hr after saving then re-booting with DST selecte. Enabling the NTP server (not the default) fixed the problem and kept the onboard clock on time.
