The official recommendation is to use the Raspberry Pi for the first time and install the system with noobs. )After entering the installation system interface let you
There should be a lot of students in how to use WiFi for Raspberry Pi connection encountered some bottlenecks, the internet said that generally need a router, in fact, we download a 360 free WiFi can, equivalent to the computer as a router to share the network, Xiang Fine steps are as follows:Step one: Download 360 free WiFi, set up your username and password.View 360 free WiFi

First, the Linux primary partition and the Swap partition are deleted. The starting position of the re-built primary partition is the same as that of the original primary partition, and then the data of the original primary partition is not changed, but the size of the primary partition is changed.

OpenVPN is a private protocol and requires proprietary clients. Therefore, it is difficult to use OpenVPN on Android (CM9 supports OpenVPN), iOS, and WP8. Combining Raspberry Pi and OpenVPN to build a soft AP can easily solve these problems.
Why is this combination selected?
I have seen a lot of articles to make Raspberry Pi into a wireless AP, but what I want to do today is to make Raspberry Pi into a NAT-enabled router, I did this because I was on a business trip to Holland and found my bambook unable to access the dorm WiFi, Perhaps because the dorm wireless router is the way to authent
