You are correct; WinPcap cannot distinguish between the adapters if they have the same name. Below is a helpful response from Gianluca Varenni from the WinPCap list:
Hi.
You answered to your question in your mail: under Win98 the names of the
adapters are NOT unique (under NT/2k/XP they are).
However, it is possible to modify those names by modifying some keys in the
registry:
a. open the registry(regedit.exe)
b. go to HKEY_LOCAL_MACHINE/[System]/CurrentControlSet/Services/Class/Net
c. you will find some folders named 0000,0001,0002...; each one
corresponds
to a network device.
each of these folders has a subfolder named NDIS, which contains
a key named "LogDriverName": it contains the names of the adapters,
as shown by winpcap. Locate the two 0000/0001/.... folders of the
adapters with the same name in winpcap, and change the LogDriverName
of
one of them (for example from "rtl8029" to "rtl8029-b").
d. close regedit and reboot.
This procedure should work (on my machine it does), HOWEVER, I do *not* take
any responsibility for this operation! Handling Windows registry is always a
possibly dangerous operation.
Let me know if it works. [It does! -DJN]
