Windows 7 is always switch to Wifi connection once I connected to Wireless LAN. How do I prevent that ?

How can I force LAN as primary connection while Wifi is only used as backup ?

When I move around, I'll need Wifi but when I am at my desk, I preferred LAN for faster speed. Can we make LAN connection as default ?

How to use LAN as primary connection ?

    This is somewhat dependent upon your device manufacturer and drivers. There may be an option to automatically disable WiFi completely upon connection to a wired network, and re-enable it upon disconnection from the wire. Alternatively, there's probably a hot key combination (Fn key plus one of the F keys) that will easily toggle the WiFi or "Airplane Mode" on-demand. Note that setting of auto-switch may override your hot key's capability. – Iszi Feb 10 '15 at 6:27

    Depending on your device, the option to set the auto-switch may be in your BIOS/UEFI and/or in the "Advanced" tab on the Properties dialog for it in Device Manager. – Iszi Feb 10 '15 at 6:29
  • Thanks for hinting to the right direction - I knew there was an option to make LAN higher priority than Wifi. I just don't know which term to search for xD – Dio Phung Feb 10 '15 at 7:42

Thanks guys for pointing to the right direction.

I have found how to make LAN the main connection while still connected to Wifi, so that we can enjoy both mobility and performance. Here are the how-to steps:

  1. Click Start --> Run, type in ncpa.cpl It will open Network Connection control applet.

  2. Click Advanced --> Advanced Settings, under Adapters and Binding tab, move your LAN connection to the top. See the explanation: connections are listed in the order which they are accessed by network services. enter image description here full size

  3. To test it, I copy 15GB file over the network. So even though I am connected to Wifi, the copying is still using LAN bandwidth (which is way faster than Wifi). You can see the Network Utilization percentage. enter image description here full size

  • Not quite the fix I was suggesting, but that'll work too. – Iszi Feb 10 '15 at 14:49
