Windows 7 Home Premium Can't Map Drives on Wired Connection, but works fine with Wireless Connection

[skybuffalo]

 

I have a new WIndows 7 Home Premium PC that times out when attempting to pull up the web admin, and eventually errors out when attempting to map a network drive to a buffalo linkstation.

 

If I disable the wired connection, and enable the wireless connection however, everything works just fine.    When both are enabled it does not work, and with wired only enabled it does not work.

 

The username and password are correct, & they work from other machines just fine.

 

I've tried the following so far: 

 

I tried the registry change as noted here

with a reboot & it still does not work.

 

I removed the mcafee antivirus software all together.

 

I disabled windows firewall.

 

I made sure that this PC belongs to the correct workgroup.   The office uses a workgroup called...  Workgroup

 

I flushed the dns, checked that the IP information is correct for both the wired  & wireless connections.

 

I disabled IPV6 on both connections, I made sure file sharing & network discovery were both turned on.

 

I tried mapping the drives by IP address.  I tried rebooting 3 times.

 

What else can I try?
