Internet Connection - WiFi & Wired?

I've been having trouble with my internet connection for the past few days. It seems to be a battle between my router and modem, but my question is about the sidebar on windows 8. When I click on the internet connection icon (?) in the lower right hand corner, the sidebar appears, showing the internet connectivity. My PC is wired to the router and modem, so should I need to connect to my router listed under the WiFi listing? Can I be wired and wireless at the same time? And if so, will it cause problems?

If you are plugged in with a cable and connected wirelessly then Windows will default to the faster connection which is usually the wired one. As soon as you unplug the cable then the wireless connection will be the connection you are using. No problems with that at all.

Thanks, Chev65! I like good news!
