First I had to use a windows system to first login after that I was able to get GNome ppp and a few quick changes to get wireless card to work.
Try the following:
I have an easier method of getting the UM150 Alltel card to work in Ubuntu 8.04 using Gnome PPP.
Open Gnome PPP:
1. Enter
number@alltel.net
2. Enter Password, "Alltel"
3. Enter Number to dial - #777
4. Press Setup
a. Press "Detect" to detect wireless card - should get /dev/ttyACMO
b. Type - "Anolog Modem"
c. Speed 115200
d. Select "INIT Strings"
a. Should see the following - ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
5. Close and try to connect.
6. If you press log you should see the connection process.
a. Take note of local ip address
7. Open terminal and log in as root/sudo
a. update routing table
1. route add default gw xxx.xx.xxx.xx
This has worked very well for me. Except for the fact that I still need to manually update routing table this is much easier than the other method I outlined before.
Hope that this works for you. Notice that /dev/ttyACM0 may not be the same in your particular system.
