RBS50 - No internet Connection

My RBS50 satellite has stopped getting any internet connection. It will connect to the network, but any device connected to it is unable to connect to the internet. I've tried both wired and wireless. It has been fine for the 2-3 years I've had it, and has been in its current location for over a year. I had not changed anything about it at the time it stopped working.

I have tried rebooting the modem, router, and satellite a number of times. I have also made sure both router and satellite have the latest firmware updates. I have tried disconnecting and then re-syncing the satellite and router.

Any ideas as to what may have gone wrong, and/or any fixes??
