Thanks again!

For me, I’m using Ubuntu Gutsy Gibbon with an AC875 Cingular card. The awesome thing about Gutsy is it will detect the card OUT OF THE BOX. I was excited after that happened

I used Sierra’s website instructions: http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=601 and tried the websites listed here, but I got the same error “Could not determine remote IP address: defaulting to 10.64.64.64″ I booted into windows, found that the remote PPP address was the same as the local, as well as the default gateway? That same ip address.

I tried to put it in statically, but it was literally changing almost every time. Then I executed the route commands to remove the default gateway, and add in the ppp and default gatway. And that worked. The problem was I had my wireless default route in there, and KPPP couldn’t (or wouldn’t) overwrite that. So for MilitaryGeek, maybe just remove your default route (using the command “route del default gw 0.0.0.0″) and when you run KPPP it should right the ship (or use the scripts on this page, two ways to skin a cat, etc).

So after a reboot with the wireless off, the routing table was clean. KPPP populated it with the 10.64.64.64 address, however, since the table was clean, I’m still able to get out to the internet. DNS addresses populated just fine.

Excellent material! From what it looks like, this is THE place to get config info for using the AirCard 875 on Ubuntu.

I am having issues with the following error:

Could not determine remote IP address: defaulting to 10.64.64.64

However, I am getting a connection and valid local IP and DNS addresses (at least they match the ones I get when I use the card on XP).

Trying to resolve this, I found something that I thought would be of help at this link:

Unfortunately, after making the suggested changes to the /etc/ppp/options file, I was still unable to ping anything.

I am using Ubuntu Feisty on a Dell Latitude D620, which has an external hard switch for disabling the WiFi, so it is pretty easy to enable/disable the WiFi when troubleshooting.

Any clue as to what I should look at next?

cut&paste, ran pon.. I’m done.
