Realtek quits

Realtek USB WLAN Client Utility Troubleshooting

Issue:   Realtek Quits as soon as it opens
Probable cause:  USB WLAN is not recognized / not plugged / USB cable DOA
Error code returned by Realtek: 250 

* The Alfa AWUS036H is not "Hot Swap"

1) Plug your Alfa !

2)  Check that your Alfa is properly recognized by your system:
Go to  >> About this Mac >> More Info >> Hardware >> USB

If your Alfa is properly recognized, you should see something as:    RTL8187_Wireless









If not: 

1) check the USB Cable
2) plug the Alfa on another Mac , repeat  >> About this Mac >> More Info >> Hardware >> USB
If your Alfa is not responding to System Profiler, it's probably a hardware issue…   sorry…
If you have bought your Alfa from a genuine authorized reseller, you'll have no issue with the warranty.  If not, we told you a thousand times: Sub-par, Knock-off, copies and junk are rampant on eBay. 

3) If your Alfa is properly plugged and responding but Realtek quits as soon as you try to open it, try the following:

Go to:
Applications
System Preferences.app
Network

In network,  Activate your Alfa (name= rtl8187)
Please ensure that you have not checked "Off" by mistake.
"Using DHCP"  is recommended unless you know what you are doing.
