I have yet to have a single issue with the router personally. Syncs just the same as HH5b, stats look very similar too, same SNR, attenuation etc.
Attainable rate did change a lot initially but now back to normal.
Has not rebooted once apart from the 14 day reboot, no drop outs of the connection (hh5b dropped at least once a day).
No WiFi slowdowns, hh5b speeds dropped to sub 10Mbps regularly on 5Ghz.
I have had 28 devices connected at once all over wireless and it still worked flawless.
For reference I do not have a single wired device so have done no diagnosis on the wired side.
1) disabled smart setup
2) set a fixed wireless channel for 2.4 and 5ghz (made a huge difference in my home - no idea why as I selected the same channel smart setup already had?!)
3) disabled upnp extended security
4) split 2.4 and 5ghz bands & connect into the hub only at 5ghz on most devices (apart those which do not support it)
