I'm not sure that UBNT makes a hub. By "hub" do you mean their managed switches, their wireless access points, their routers, or their long-range outdoor point-to-point wireless radios? I own three indoor Wifi APs and have had good service from them. I also own one of their three-port routers. About ten or so months after I purchased the router, I would get spontaneous reboots that became increasingly more frequent over time. It turned out that the external power supply that shipped with the thing had become unreliable. I replaced the power supply with another suitable one that I had lying around and I've had no troubles in the year+ since then.
