Wireless Raspberry Pi
Your Raspberry Pi should easily connect to the Ethernet easily after you have Raspian or another distro setup on your SD card. However, using wireless could be simple, or it could take a little workover. This tutorial will show how to get that wireless internet working with a plug and play wireless adapter like ‘Ourlink’.
To enable wireless connection,
1) Open network-interfaces file
2) Navigate to the wpa_supplicant folder
3) Add your wireless network settings and save the file. Hopefully, one of the two codeblocks is sufficient for your connection to succeed.
Now, you can open your GUI, be connected to the Internet and surf websites.
