 +====== Using Ethernet Connection to HSIO-2 Board and WiFi Simultaneously ======
 +
 When using an ethernet cable to hook up a computer with the HSIO-2 board, you may find that your wi-fi connection stops working. The reason for this is that your computer thinks both the wi-fi and ethernet connection are methods of connecting to the internet. As ethernet is generally faster than wi-fi, the computer will automatically ignore the wi-fi and start trying to use the ethernet port for internet stuff. The HSIO-2 board receives this info, doesn't know what to do with it, and just throws it away. When using an ethernet cable to hook up a computer with the HSIO-2 board, you may find that your wi-fi connection stops working.

-If you want to learn about networking and IP addresses and things like that, [[http://www.aboutdebian.com/network.htm|this]] is a really nice and easy read. It will probably make your life easier in the future if you do a lot of computer stuff, but you don't have to read it. Anyway, what we see here is that the ethernet connection (here named enp1s7) has a metric of 100. Since this is lower than the metric of 600 used by the wifi, the computer automatically tries to use that connection. We need to set it to something higher. Type the following commands (if the IP address you see is different, be sure to use that instead).+If you want to learn about networking and IP addresses and things like that, [[http://www.aboutdebian.com/network.htm|the first section of this]] is a really nice and easy read.

 Now if we look at our connections again with: <code>route -n</code> we'll see that everything is fixed and we can use our wifi again! Now if we look at our connections again with: <code>route -n</code> we'll see that everything is fixed and we can use our wifi again!

 +This needs to be done every time you connect the ethernet cable.
