I have used this router with a vodafone dongle (in portugal for 5 or 6 years. The dongle is a huawei E220 with a 3g data sim card inserted.
It stoppedworking a few days ago (and despite efforts I could not get it to work) so I bought a new dongle from Vodafone Model K4201Z. But I cannot get this to work. Unfortunately the Linksys web site does not list compatiable dongles.
In the meantime I have reverted to my old dongle and this is now working!!!!! (Don't ask me why...even the computer technician couldn't understand)
But I would like to use the new dongle if possible as it has the latest firmware. Can anyone provide any help please with set up, analysing, testing or compatability please?
