IPv6 traffic killing my wireless network

[clyde.wilson]

I have a large wireless network in a hospital i support.  After an upgrade of all the wireless PCs to Windows 7 my wireless network is being crushed by IPv6 traffic.  This has affected our Vocera system to the point where it is no longer usable.  I am trying to find a way to block all IPv6 traffic.  Our system admin guys dont want to disable IPv6 via GPO and have suggested that i find a way to block it on the network.  Vocera support claims an access list on the VLAN that our wireless PCs are on blocking IPv6 traffic would solve the issue.  I'm not 100% sure how to do this.  If anyone else has had this issue and knows a fix i would appreciate any help.

Maybe try this

config wlan IPv6support {enable | disable} wlan_id

I guess you might also be able to use ACLs to block ipv6.

Might also want to look at this. Maybe just setting it up right can help with the ipv6 traffic.
