First, connect the PC to internet router and access point.Next, click the “network” button on the taskbar, and open Network and Sharing centre (yours may look different, mine signifies a wireless network, yours will most likely be a PC with a plug next to it)
Click “change adapter settings” on the left hand side and then right click your INTERNET Connection (NOT not on the adapter that is connected to the access point), and select properties
Under the “Sharing” tab, select “allow other network users to connect through this computers internet connection” and then select the connection through which your PC connects to the internet (in my case wireless)
ISC changed the IP adapter access point automatically. Go to the adapter where the access point is connected, view the properties and add the new DNS. 18.104.22.168 are recommended. Remember the assigned IP, usually 192.168.0.1 or 192.168.137.1. It will be necessary to configure DHCP server later
IMPORTANT: Do not change the IP assigned by windows. If you need to change to access the access point, you should leave it as it was originally.
Then with a little luck, you should be able to connect to the internet through both PC’s at once!
