After downloading and unzipping slamr 2.6.24-19, I ran setup and copied down the output of the setup.sh. glenn(a)glenn1:~/Desktop$ cd slamr-2.6.24-19-generic glenn(a)glenn1:~/Desktop/slamr-2.6.24-19-generic$ sudo ./setup installing drivers for kernel version 2.6.24-19-generic driver=slamr Installing the Debian packages supporting autoloading *dpkg: error processing sl-modem-daemon_2.9.10+2.9.9d+e-pre2-5ubuntu4_i386.deb (--install): package architecture (i386) does not match system (amd64)* Errors were encountered while processing: sl-modem-daemon_2.9.10+2.9.9d+e-pre2-5ubuntu4_i386.deb Copying over newer files Making folder /lib/modules/2.6.24-19-generic/extra Copying drivers to /lib/modules/2.6.24-19-generic/extra Checking driver install slamr.ko slusb.ko ungrab-winmodem.ko Copying newer slmodemd to /usr/sbin/ Checking slmodemd version.

I don't think changing the modem will achieve anything since the modem driver itself is written for 32 bit systems. Glenn.
