WIN8 Notebook wireless network connection but not on the net how to do

First use the computer that can surf the Internet (the computer connected with the wireless router) into the wireless router backstage (do not understand the children's shoes please Baidu), find "Wireless Settings"-"Basic settings"-look at the wireless mode is set which, write it down.

Look at "Network parameters"-"LAN port Settings", see: DHCP Server "is turned on, if not, choose to open, as well as the" default gateway, "The gateway address also write down.

Back to the computer desktop, the lower right corner will see a wireless network, but the display of yellow exclamation point, this is an abnormal network.

Right-click the wireless network-select open Network and Sharing Center in the pop-up box

In the network control Panel that pops up, select Change adapter settings, and the displayed page is the NIC that you have already driven or set on your current computer.

As shown in the 2nd picture below, one is a wired network card, one is a wireless network card (show WLAN), from here you can see the mode of wireless network card ( Wireless cards like small d are 802.11g mode, this is the first step of small d requirements to write down the reason, if you find that the wireless router mode does not contain the wireless network card display mode, need to be modified in the router with G network, small D recommended 11BGN this mode, because compatible with three kinds of wireless network mode )

Right click on the "WLAN" Network-select "Properties" in the pop-up box, a WLAN property box pops up, select "Interner protocol version 4", and then click "Properties"

At this time we can see, the wireless network inside the Setup interface, if the display is not automatically get IP, this situation is generally previously manually entered IP, now replaced the network environment, resulting in the computer's gateway and wireless router gateway is not the same network segment, then we have two methods:

1, Manual input: See the first step we write down the gateway, such as small D wireless Router gateway is: 192.168.1.1;

On the computer, must modify two points, one is the IP address, one is the default gateway, how to modify it? Like IP address: 192.168.1.x (1

2, automatically obtain IP, this method, the need for wireless router DHCP has to open (DHCP is a lazy way, the computer automatically distributed from the wireless router IP over, but will cause may be rubbed against the net, but then, as long as the wireless password set up a bit more complex, not pure numbers, is basically very safe)
