Hey, I recently purchased an Acer Aspire One 531h. I put a telecom sim card in, I can see the telecom's HSDPA network (along with the vodafone 3g and 2g networks) on Acer's 3g connection manager, but when I try to connect it says "An error occured during connection. Error 619. Your authentication settings in the current profile may be invalid". 
In the connection manager there's no Telecom firmware option for one reason or another (I've updated the software/drivers), but they do have an option to overwrite the APN/homepage, which I did using internet.telecom.co.nz and http://pdaportal.telecom.co.nz. Still nothing however. 


So, failing that, I read on here about setting it up manually as a dialup connection. I changed the initialisation string to AT+CGDCONT=1, "ip", "direct.telecom.co.nz" in device manager, setup a new Dialup connection calling *99#, username/pw blank and tried connecting, but it gets to "Registering your computer on the network", then I get a "Error 619. A connection to the remote computer could not be established, so the port used for this connection was closed."


I've tried both internet.telecom.co.nz and direct.telecom.co.nz in both cases. I can also send/receive SMS's from the connection manager. Anyone have any ideas on what I've been doing wrong? 
I'll get my grubby little hands on a vodafone sim card and see if that encounters any trouble, as there is a VFNZ firmware option in the software. If the firmware's the issue, maybe I should try editing one of the existing revisions to a telecom one?


Thanks!
