A few months back I posted a howto guide on getting this mobile broadband card working with Linux, what I failed to mention was I continued to work on these scripts. I feel it is appropriate to post a status update on what I use now especially given there appears to be no further updates on the NetworkManager front. I no longer use UMTSMon as I found it relied on AT+CSQ for the signal quality and during UMTS and HSPA connections, the f3507g/dell 5530 returns either the previous GPRS value or 99,99 which UMTSMon considers as no connection available. I've used a simplified wvdial.conf scripts and now do the rest of the radio work using python. wvdial.conf # Author: Barry John Williams # Creative Commons Attribute-Share Alike 2.5 UK:Scotland Licence [Dialer defaults] New PPPD = yes Stupid Mode = 1 Modem Type = ACM Modem Modem = /dev/ttyACM1 Init1 = AT Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CGDCONT=1,"ip","internet" Baud = 460800 I...

This card does not work conveniently with the bundled Network Manager software, but replacing NetworkManager with other utilities will give the ability to get online using a pretty GUI and not have to resort to using wvdial and the command line... It should also work with the Ericsson f3507g as I believe the Dell 5530 is a rebadged version of this module. Check Hardware First you need to check the modem is detected correctly. On my computer, the modem is detected out of the box by the cdc_acm module and exposes three serial ports (/dev/ttyACM[0,1,2]) for communication. Check by running: dmesg | grep ACM Mine shows the following: [ 34.385302] cdc_acm 1-6:1.1: ttyACM0: USB ACM device [ ...
