Raspberry Pi connected to PC

Less than a day before Raspberry Pi started, SSH Raspberry Pi has been using the routing + wireless Nic configuration. I want to take Raspberry Pi to my business trip tomorrow, but the hotel room has only one network port. It is usually used by the brothers to connect to a small wireless route. Connecting Raspberry Pi seems to be a problem. GOOGLE has found a direct connection to the PC. First, set the wireless network card of the PC to share, and select the local connection in the home network connection. After the wireless network card sharing setting is complete, you can see in the network device column on the network page, the Internet getway device icon is added. This figure indicates that the system assigns the local wired network card the role of the router. In cmd, enter arp-a to search for the IP address allocated by Raspberry Pi and SSH the IP address directly. At the same time, ping Baidu and OK. This test uses a direct connection. It is reasonable to say that the cross line is used. After checking on the Internet, all the modern network cards have the Auto MDI/MDIX function, which will automatically identify the foot of the network cable to adjust the line.
