Can you reach the advaced pages? If so try a reinstall.
If you can't reach the advanced pages try 169.254.0.1 If that works try a reinstall.
If none of that works you could push the emergency reset on the back and then try a reinstall. It will most likely clear all saved data so you will need the data from your install page.
My install page above. If you do not have that data you are probably out of luck.
Your data would/should be the same as mine except for the lat and long. Worth a try.
