I use the Cisco VPN client version 4.6.04.0043 to VPN from home into my company's network. Once connected, I use the Cisco IP Communicator desktop phone v 2.1. If I'm using a hard wired connection, everything works fine. However, if I'm working wireless, I cannot get the IP Communicator to work. It just sits there 'registering', but never connects. I have edited the preferences and change the NIC from the wired to wireless card as well as unchecked the 'Optimize for low bandwith' checkbox. Any ideas on what else I can do to make this work?
