After issuing "/sbin/modprobe usbserial vendor=0×1410 product=0×2110". Once that was done, the modem appeared as /dev/ttyUSB0 and /dev/ttyUSB1 (someone said they think the latter is a management and diagnostic interface; the former is used for the PPP connection). I was then able to use KPPP to set up a dialer connection. I started the dialer and bam it connected. Once connected I see this:

Once it actually starts pulling data, it seems a little quicker but then bogs down when trying to go to the next website. I manually changed the "serial" bit rate in the configuration files to the same way it was set in XP (230400 bps) but that did not help.

That is an IPV6 address.

Can we see your: /etc/wvdial.conf ?

It is usually a matter of the 'correct' initialize/dial strings.
