Hey everyone, I'm brand new but just fired up the Dreampi and I'm online! The problem I had was getting a WiFi unit or just Ethernet. I didn't really trust the WiFi on the Pi and I didn't want to run 40ft of Cat 5 to my basement. So I got one of these.
D-Link DHP-600. (older model. $23 on eBay)
It allows you to run Ethernet through your electrical sockets to anywhere in your house. To my surprise is works great. You must make sure to plug directly into the outlet and not an ext cord or surge protector.
This seems to be a great compromise. I still have the flexibility of mobility with more reliability. At least so far.
Not sure if this was the best place to post this. See you online!
