I have just installed an Orange ICON 225 Mobile Broadband USB and it has disabled my Network Connections so Vista says it is unable to find any networks so I can't connect to my Home wireless network. How do I re-enable the system so I can use windows vista to configure my wireless network settings??? Having done some research it appears I should have a Wireless Networks tab on the Wireless Connections Properties screen but this is missing. The only tabs I have are: Networking & Sharing
