|I would try recycling the power before doing anything else. Simply unplug it, count to ten slowly then plug it back in. If it starts working normally, you're good to go. If it doesn't, I'd recommend checking to ensure you have the most up-to-date firmware and if you don't, update yours. If that doesn't fix it, then try a full reset to factory defaults.|
If none of the above works, you're router is likely done and in need of replacing.
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.
