Aircard 860 PPP connection problem
Hi,
I am having trouble getting a Sierra Wireless AirCard 860 modem to connect using PPP. Looking at the log, I think it is getting past the CHAP authentication but cannot get past the LCP/IPCP negotiation. Here are the ppp options I am using and the ppp log:

Can anyone tell me what is happening here? The modem is a Cingular AC860.
Thanks in advance.

Problem with Sierra Wireless AirCard860
Hi,
I am having the same problem.
My ppp options:
lcp-echo-failure 0
lcp-echo-interval 0
hide-password
noauth

defaultroute

remotename dial_up
updetach
I run this command to connect pppd:
sudo pppd file /path/to/ppp_options user ISPDA@CINGULARGPRS.COM connect $'/usr/sbin/chat -v -f /etc/chatscripts/gprs -T 2,\\\"IP\\\",\\\"isp.cingular\\\"' /dev/modem
and get the following output:
speed 2 not supported
Serial connection established.

I'm not convinced that the "speed 2 not supported" is a problem.
Any help would be much appreciated!
Thanks
Aircard 860 connection problem
Hi davidjagoe,
My problem was resolved recently when I realized my Access point name (APN) was not set. Once I set it to isp.cingular, the problem went away. Now I am able to connect and obtain an IP. My ppp options and chatscript are as follows.
ppp options:
-----------------------
-detach
/dev/modem
115200
debug
nodefaultroute
usepeerdns
noauth
user ispda@cingulargprs.com
password CINGULAR1
show-password
crtscts
lock
lcp-echo-failure 0
lcp-echo-interval 0
ipcp-accept-local
ipcp-accept-remote
connect '/usr/sbin/chat -v -t3 -f /etc/ppp/peers/ac850chat'
ac850 chatscript (provided by cingular):
---------------------------------------------------
'' AT
#'' ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK AT+CGDCONT=1,"IP","isp.cingular"
TIMEOUT 30
OK ATD*99#
CONNECT ''
I read the following somewhere, it may be worth trying something like this:
# Incorrect APN or CGDCONT variable is a
# frequent cause of peer LCP TermReqs
# So try each setting at least once! =)
#REG:\s1 AT+cgdcont=1,"IP","proxy"
#OK 'AT+CGDCONT=0,"IP","proxy"'
OK 'AT+CGDCONT=1,"IP","proxy"'
OK 'AT+CGDCONT=2,"IP","proxy"'
#OK 'AT+CGDCONT=0,"IP","isp.cingular"'
#OK 'AT+CGDCONT=1,"IP","isp.cingular"'
#OK 'AT+CGDCONT=2,"IP","isp.cingular"'
I also noticed from your output that the chap authentication is happening with
ISPDA@CINGULARGPS.COM. Was there a typo in the cingulargprs.com or is this also a valid username? Have you tried the non accelerated option with user name
isp@cingulargprs.com?
Hope this helps.
Deepa
