In the last month or so my 3.0 Hub has started to lose all its settings after a powercut. I have to set it up as a new router after every occasion. It will also occasionally randomly reset the settings without there being a power cut.
I'm making sure I save the settings but it still happens?
Mine happened just last night. It is a pain as I have a number of different settings I have to keep entering in. I'm not sure why it should suddenly loose these. I wonder if there is an internal back up battery?
If you havent tried this already, next time it happens, do a pinhole reset to factory settings. Push the pin in to its stop point and hold for a "timed" 40 seconds do NOT restart the router after that. Then put in all your changes - see if that helps.
