If you see can spot the afflicted device in Device Manager, you can check the details and determine the VENdor and DEVice ID of the device and look it up and figure out who makes it, what kind it is, and then you will have some clues about what drivers you need.
To start Device Manager, click Start, Run and in the box enter:
Click OK to open the Device Manager and look for devices that have yellow question marks or red Xs.
Right click the unknown or offending device, click Properties and look at the Details tab for the identification string that will tell you the hardware VENdor and DEVice.
Check the Details tab and if you see something similar to this example:
Now you have a VENdor and a DEVice which you can look up using a variety of methods, one of which is:
For the example above, that reveals it is a SiS191 Gigabit LAN & SiS0190 LAN device, so I would look on the SIS World Wide Web page for
the latest driver and find all kinds of good information.
If I needed to give them a hard time about their adapter, I would be happy to do so since I also now know where they live:
NO.180, Sec.2, Gongdaowu Rd., Hsin-Chu, Taiwan 300
Rm A202, 1355 Jinjihu Avenue, Suzhou Industrial Pa
Taiwan, Suzhou (China)
You can also just Google the device identification string (something like VEN_1039&DEV_0190) and sometimes get some results that way.
