|I would try a factory reset on the unit. Information on how to do that should be in the manual. Once reset, I would try to connect to the management interface again according to the manual's instructions. If you still don't succeed, there may be a problem with the unit. |
If it's new and/or still under warranty, I would have it replaced. If it's not, you'll probably have to buy a replacement.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
