Lan to Wireless Error Message

[BJ1200]

This is driving us crazy.

When our Win7 laptop is connected via ethernet cable we are able to access our Network Storage Device (mapped drive letter), internet browsing works great. If we unplug cable and use wireless, we get an error message trying to access to NAS folders, but can still browse. The laptop, NAS, and cable modem are connected to the AC66U.

"An error occurred while reconnecting...
Microsoft Windows Network. The local device name is already in use.
The connection has not been restored."

How do we fix this?

If you run up a command prompt and type 'net use' I think you'll see that the drive/server is still 'connected' even after you switch networks.

I believe that Windows is attaching the mapped drive to the LAN NBT adapter, so when you try and connect over wireless adapter it sees the UNC name is already connected, and throws the error. This can be a problem especially if you have the drive mapping set as persistent (reconnect at logon).

The easy way to prove this is to manually disconnect the drive (right-click, disconnect) before you switch, or reboot and only connect via the wireless initially. If it works, then that proves the theory.
You can also manually disconnect with a 'net use /del <server\folder>' from the command prompt if need be to manually reset the connection.

Windows isn't very clever at this type of NetBIOS switching between adapters in my experience.
