|Well, the fact that neither wired, nor wireless, seem to be working makes me think maybe it's your router. Let's try troubleshooting it and see if that gets you back up and working.|
Do the following:
Step 1. Recycle the power on your wireless router (ie: unplug it, count to ten slowly, then plug it back in) and see if that doesn't fix the issue.
Step 2. If that doesn't work, check for a newer version of the firmware. If there's a newer one, apply it.
Step 3. If it doesn't fix the issue, the next thing to do is reset the router to factory defaults and then reconfigure it.
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.
