TROUBLESHOOTING GUIDE 
1. I cannot connect to the network with  
  the SMC wireless adapter. 
- Check if other wireless computers in your home/office are  
 able to connect to the network. If none of the wireless   
 computers is able to connect, power cycle the wireless  
 modem (Cable/DSL) / router/ access point and try  
 connecting again. 
 Power cycle: Unplug the power cable from the wireless  
 modem/router/access point. Wait for 10-15 seconds then  
 power on your modem/router/ access point. 
- If you only have one wireless computer in the network, or if  
 other wireless computers in your network are able to  
 connect, try the following steps: 
 - Start the SMC Utility. Scan the wireless network and  
   reconnect. (Refer to step 4 - 7 in the front page) 
  If the SMC utility displays available wireless networks but  
  you cannot connect, make sure you have entered the  
  correct encryption (security) type and password. The  
  password is case-sensitive. 
  If the SMC utility does not scan the wireless network: 
  - Unplug the adapter and plug it into a different USB port.  
    Rescan the wireless network. 
  - If you have a laptop, try moving closer to the wireless  
    modem/router/access point and rescan the wireless  
    network.
