Hello, I just performed a clean install of 13.04 and I am unable to connect using my internal Dell 5530 Mobile Broadband card. I am quite new to Ubuntu, but with the help of this community, I am learning every day.
Network Manager recognizes the connection, and takes me thru the setup. I am using the AT&T Laptopconnect (Data cards) settings. The apn is correct: "broadband" and the number to dial is also correct. However, when I attempt to make a connection, it tries and then returns "Network Disconnected - You are now offline"
Has anyone successfully used their onboard mobile broadband card with UBUNTU 13.04? Can you tell me where I need to go to configure the card's commands? Or perhaps can I get a "sniffer" on this to see exactly where the failure is occurring?
Any help, advice, ideas, and suggestions are welcome. And thank you all in advance!
