27 
Added successfully!   
Now you can click    to connect the wireless 
network via the profile. 
Ad-Hoc 
Ad-Hoc is a special wireless mobile network application mode. All nodes in the network are equal. Usually it is 
used to do a resource sharing between LAN computers. 
Using the Ad-hoc mode to establish a wireless network requires that each computer should be equipped with a 
wireless network adapter. By connecting these wireless adapters, computers are able to share the resources.   
Note that Ad-Hoc feature is unavailable for Windows 8. 
Instance   
PC1 (Desktop) is sharing some files with PC2 (Desktop or Laptop). Now Ad-Hoc mode is working. 
If the SSID of the wireless router or AP you 
wish to connect is hidden, then the wireless 
adapter cannot scan the SSID, thus you need to 
connect it by creating the corresponding profile. 
Note 

28 
Process 
1) Create a new Ad-hoc profile on the wireless adapter of PC1. 
a. Click . 
b. Select Ad-Hoc Network Type.

And click OK to save. 

31 
3) Configure a static IP address for wireless adapter of PC2. Configure the wireless adapter of PC2 a 
static IP address which is in the same network segment with that of PC1. For example, IP address of PC1’s 
wireless adapter is 192.168.1.6; then you should set that of PC2 to be 192.168.1.x (x can be any number from 
2~255). 
4) Connect the SSID you have set to PC1’s wireless adapter. (Windows 7)
