Hi @Babatunde and welcome to the forum.
When this happens to me I find the following procedure get me back up and running again.
Put Glass to Standby and then unplug both your Glass TV and router. Leave for a couple of minutes and then plug your router back in and wait for it to finish rebooting. Once it has rebooted plug your glass TV back in and when that has also rebooted it should have reconnected to the internet.
The following may also be of interest but if you are still not able to resolve the issue I would call Sky for some additional troubleshooting.
