windows share doesnt work over wired lan

[patrik]

OS- windows vista 32-bits

Control Panel -> Network & Sharing center
Network discovery ON
File Sharing ON
Public folders Sharing ON
Password protected sharing ON
Media Sharing ON

Window firewall turned OFF
McAffee firewall turned OFF

Case 1: Connect to LAN using wireless connection (network type= private)
I can open the windows share, look at the list of shared folders & open them.

Case 2: Switch from Wireless to Wired LAN connection (network type= private)
I can open the windows share, look at the list of shared folders. But can NOT open any shared folder. Does anyone know why this may be happening? As far as I can say all is equal between the two networks. I have opened up appropriate ports on the router as well.

All I am doing is change from Wireless to Wired connection. Everything else is equal. I want to switch to wireless to improve file transfer speeds.

Here is a network trace from wireshark. I keep seeing re-transmissions for the packet highlighted below. Eventually the request times out at the client end.

Post the output of ipconfig /all from both connection types. See if there are any obvious diffferences:

Click on Start then Run or press Window key (next to left Ctrl key) +R and paste the following into the Run box, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close.

If you don't have a Run selection off the Start menu, see here: Enable Run Command on Windows 7 or Vista Start Menu, or How to access the 'Run' box in Windows® 8.1 - YouTube or just press Windows Key (next to the left Ctrl key) + R, or open the Modern desktop, type run then click on Run that appears.
