When using the Chinese Simplified or Chinese Traditional version of Windows 7 or Windows 8, repeatedly installing and removing and reinstalling Realtek's network driver over the inbox Realtek driver can cause the Realtek network card device name to have a #2 or #3 ... #n number after the name in Device Manager, even though a single network card is installed.
The following picture shows the Realtek PCIe GBE Family Controller device name that may appear in Device Manager when this occurs:

This issue can occur when the following steps occur on a Chinese version of Windows 7 or Windows 8:
1. The inbox Realtek PCIe GBE Family Controller will automatically install.
2. Install the Realtek driver (from Realtek) over the existing driver.
3. Remove the Realtek driver using Add/Remove Programs, or from Device Manager.
4. Install the inbox Realtek driver again. The device name will have a #2 after it.
5. If steps 1-3 are performed again, the device name will be incremented by 1 each time (i.e. #3, #4, ...).
This behavior occurs due to the way that Windows builds the friendly name for the device, when the Realtek network driver is installed over the Windows 7 or Windows 8 in-box version of the Realtek driver, on a Chinese version of Windows. The following Realtek network driver names can be affected by this issue:
Realtek PCIe GBE Family Controller
Realtek PCIe FE Family Controller
