MBP Airport Network Problem After VMWare use

I'm an airport user. This means in the office I've got a connection secured by EAP-TLS using a respective certificate. At home there's an airport network using personal wpa and cisco VPNClient to tunnel to the company network.

Opening the MBP at the office establishes a connection to the company network automatically. I'm just switching location due to DNS entries. The problem? Once in a while I'm coming in the office the network activates (seen in menu bar and controlled by checking in Internet Connect 802.1x tab) but the browser can't open anything, there's no connection, somehow.

The only solution is to re-boot the machine. I have no prove, but it happens when I've been using VMWare and I'd say I've got the problem only to connect in the office.

I tried today a boot.sh stop but there's been no change.

I definitely missing a deeper network guide for Fusion as there was/is for Workstation…

You're not alone. This issue has been reported elsewhere. Try toggling your Airport Off and On the next time this happens. Then refresh the guest's IP address.

I have this problem only with my MBP 17'' SR with an N adapter. Using my G base station its fine. If I turn off networking in my VM then all is OK too.

+1 here.

I think this is an issue with the 802.11N cards in the new SR machines.

Everything was working fine in my old MBP.

With the N card it appears that the guest and host are sending the same MAC address in bridged networking mode and this causes the network conflict.

The router doesn't know which IP to send the info to.

I have a BlackBook which doesn't have an 802.11N card.

Are you seeing the exact same problem (duplicate MAC addresses in routing table)?

Then the problem is more widespread.

Hopefully they'll get it fixed soon.

addresses in routing table)?

Not sure how the routing table came into the conversation, but no - my router 'sees' two unique MAC addresses: one for the host, and one for the guest (as defined in by the vmx's "ethernet0.generatedAddress" attribute). Interestingly, it places both devices into its br0 interface. See the attached screenshot.

Umm, if you look at the .53 and .150 addresses you'll see that both have the same and not unique MAC addresses. So you do in fact have duplicate MAC addresses there.
