So I have noticed that this has become a bit of an issue on Windows 7 laptops lately. Despite having re-ordered the interfaces to prioritize the wired connection in the network adapters advanced settings, the system tray icon still appears as the wireless signal strength icon.
I have double-checked
route print and it indicates that wired does, in fact, have a higher metric than wireless.
netsh int ipv4 show interfaces also confirms this. However, I do note that the wireless index is 11, whereas the gigabit NIC's index is 18. Not sure if this would be the cause, but I also cannot figure out how to change these numbers.
