I have a problem with Acer Aspire 4810TZ laptop (Win7 Pro, 64-bit). After installing Cisco VPN client, I could not connect to ANY network (LAN, wireless). Now, I've uninstalled Cisco, even run system restore, but still can't connect to network. On all available wireless it says "limited access", and on LAN it's just not connected (however, lights on the NIC are ON). Any suggestions?
