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.
