[Trisquel-users] AnyDATA ADU-520A broadband USB modem

[antonio . pedro . pina]

Hi everyone! I'm trying to use in Trisquel 4.5.1 my AnyDATA ADU-520A USB 3G  
broadband Internet modem, but i'm having trouble. The device is detected but  
when i try to connect nothing happens.

My ISP provides an install and connect script  
(http://www.zapp.pt/c/document_librar...&groupId=10209) but it's for a  
different model; i've tried it anyway but it doesn't work. The modem  
manufacturer provides support for MAC and Windows  
(http://www.anydata.com/Support.html), but not for Linux.

Following some tips available througout the Internet, i've tried to edit  
/etc/ppp/chap-secrets, /etc/ppp/pap-secrets and some other related files that  
i don't remember at the moment, but that didn't help either.

I also tried to use wvdial, wvdialconf and have configured /etc/wvdial.conf  
file... after a few seconds i get a message saying that the modem isn't  
responding. I'm not sure if the dial commands are allright, but i've inserted  
them as they are in the script that my ISP provides  
(http://www.zapp.pt/c/document_librar...&groupId=10209). I followed the 2nd  
method (without installing any additional software/package/file), as  
explained here: http://trisquel.info/en/wiki/configure-3g-modem; but, as i  
said before, it didn't work.

I'm going insane with this one. Shouldn't the network manager be able to  
handle this? I need a follow-through with this. Can anyone help me, please?
