Topic # 30394 6-Feb-2009 17:14
Send private message

I am trying to the Telecom Sierra Wireless USB modem working but nothing. This is what I’ve done:

I plugged the Sierra Wireless CDMA 3G USB modem. On a terminal session "modinfo sierra" shows that a driver *is* already in the system.

Visited http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=601 and downloaded the scripts. Unpacked those and copied cdma and cdma_chat to /etc/ppp/peers.

Then opening a terminal:

su
gedit cdma

Commented out noauth and added username and password. Save and close.

I then ran "pppd call cdma" and got the following:

Dialing...
Serial connection established.
using channel 6
using interface ppp0
Connecting ppp0 <--> /dev/ttyUSB0
PAP authentication succeeded
Protocol-Reject for 'Compression Control Protocol' received
Cannot determine ethernet address for proxy ARP
local IP address 166.179.151.199
remote IP address 166.179.144.1
primary DNS address 202.27.158.40
secondary DNS address 202.27.156.72
script /etc/ppp/ip-up started
script /etc/ppp/ip-up finished, status = 0x0

And that's it... No connectivity on other programs...

Any ideas?

I would expect some of the commands like su then [command] to change to sudo [command] (for ones like Ubuntu) etc...

Possibly try doing that for commands, and make sure the permission flags have been correctly set for the files (sudo chmod a+x ip-up.local ip-down.local)

Otherwise maybe you could try the driver listed on the site (build tools required)

(The links below are assuming the T-Stick is the C597... if my eyesight is correct)

I've found a different, more updated page:

http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=1232

and here are some threads I've found

http://ubuntuforums.org/showthread.php?t=804964
http://forum.eeeuser.com/viewtopic.php?id=27824

The threads are dated when 8.04 was around (what the Mi Edition is based on), so I think it would be pretty useful.

Do be aware that there may be problems with recompiling with the other kernel in the instructions (2.6.21 rather than the 2.6.24 in Ubuntu 8.04, not sure what the kernel is in the Mi Edition - check by running uname -r)

It may pay to have follow through the original Sierra instructions in the first link I gave, since they have an updated driver there.

It looks like its connected ok

after its is connected can you look at      netstat -rn    (or     ip route  )      to show the routing table

maybe it hasn't got a default route and you may have to add in the options
defaultroute
replacedefaultroute


Thanks

Yes, I would also say that it connected without error message and it looks like it even got itself a nice IP address. Maybe you could post here what the output for the commands 'ifconfig' and (as suggested) 'netstat -rn' is. Furthermore, could you print the contents of /etc/resolv.conf, please?

Strange thing...

If I open another terminal and ping a host the name resolution works, and the ping results return ok. Thunderbird works fine, but Firefox can't find anything - it says it is offline...

Looks like you are almost there. Just out of curiosity: You did uncheck the "Work Offline' item in the 'File' menu of Firefox, right?

I found that Firefox can default to 'offline' if it was started once when there was no network connection and it then remembers that state even after restart.

Done. I looked at that before but because of the screen colours it wasn't quite visible.

Connected and browsing too.



Good to hear!

The only thing is that I have to run a terminal session to initiate pppd. It should have a GUI dialer somewhere...

Other than this, it's connected.
