I went away on a trip into the mountains about a 2 hour drive from home and tried to connect with my laptop there. When I got back home, my computer could not connect successfully to my home network. It says it's an unidentifed network with no network access. Other family members laptops work fine, and they didn't take them with like I did. My laptop is wirelessly connected and when I tried plugging it into the Ethernet cable it gets the connection but can't do it wirelessly. Any help?
