what i did was download and installed the windows7 version of the program within the realtek site ("Realtek") then i closed the utility and i changed the 8187.ini with this line below. after editing or replacing the 8187.ini try to run the utility again. it will be ok now
for those with other model chips like the RTL8185. look for the 8185.ini then use the lines above. just dont forget to change the 8187 to 8185 part in the RtWLanTitle and Model_Name. so you wont get confused with your part number everytime you look at its utility.
[WLan Utility]
WZC=0
RtWLanTitle="REALTEK RTL8185 Wireless LAN Utility"
MANUFACTURER="Realtek"
Model_Name="RTL8185"
Yes its working fine, but i have one issue, the Internet Connection Sharing is not giving Automatic IP Address I have to assign manually to the device ( mobile )
