Help! Unidentified Network Internet Access Problem

've spent hours during the last two days reading all sorts of threads trying to fix this problem without any success. I would appreciate any feedback from anyone who has had some luck with this.

I'm trying to access internet through a public wifi network on my laptop (Lenovo ThinkPad), but I get the "Unidentified Network. No Internet access".

My apartment mate has a Mac and has no problem with the exact same network.
Operating System: Windows 7 (64 bit)

IPv4 Connectivity: No Internet access
IPv6 Connectivity: No network access

ipconfig/all

When I try ipconfig/renew, I get a message saying that no operation can be performed on Wireless Network connection 2 while it has its media disconnected.

I use McAfee security software.

Thank you!

Thanks for the tip, Vista King.

Isn't the point of McAfee to protect my laptop? So you are suggesting uninstalling it and then using this network (which is my network at home) without any protection?

I was thinking that it might be a problem with my adapter driver...

Done. Here we go.

Thanks.

Ok. Here is the file.

I still can't access internet, although the network shows "connected", as before.

I noted one difference. Before the activity in my wireless network connection status showed 104 bytes sent, 0 received. Now it's 104 bytes sent, 42 received. Can't can get through internet though.

I haven't uninstalled it yet, no.
