I installed 2 of these and they both have the same performance issues. I have to restart them multiple times a day because the device loses connectivity between its own wireless interface and its own wired interface. When your computer is connected via a wireless network, you lose access to everything outside of the device. You can't even ping the device's own IP address. If you reboot it works for a while. I did a little research and found this to be a common problem. Now I'm trying to get her back.
