configure CISCO881GW router to use APN with no user name and password

Unanswered Question
Dec 18th, 2009

Hi there,

I am trying to configure the above router to establish 3G connection, but we are based in UK and our provider three.co.uk has supplied us with ONLY APN: 3internet - we are NOT meant to use user name or password and we have asked them, but they can't provide us with one..., but the router seems to require it?!?

when configuring the router I get these "% Incomplete command" messages

Should I assume that the router can ONLY be used with APNs that have user names and passwords?

CISCO881GW(config)#interface cellular 0
CISCO881GW(config-if)#ppp chap hostname
% Incomplete command.

CISCO881GW(config-if)#ppp chap password 0
% Incomplete command.

CISCO881GW#cellular 0 gsm profile create 1 3internet chap
% Incomplete command.

CISCO881GW(config-line)#login
% Login disabled on line 3, until 'password' is set


Any help appreciated

CISCO881GW#sh cellular 0 profile 1
Profile 1 = INACTIVE*
--------
PDP Type = IPv4
Access Point Name (APN) = 3internet
Authentication = None
Username: , Password:

* - Default profile

chat-script gsm "" "ATDT*98*1#" TIMEOUT 60 "CONNECT"

!
interface Cellular0
ip address negotiated
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
encapsulation ppp
dialer in-band
dialer string gsm
dialer-group 1
async mode interactive
!

!

line 3
exec-timeout 0 0
script dialer gsm
login
modem InOut
no exec
speed 384000

!

I have this problem too.

As long the ISP does not request authentication, the chap commands are optional.

You can verify that with "debug ppp auth" and "term mon".

i can use this SIM card in another non-cisco router with no problem - only APN is needed with no user name and password

I do however see auth required below:
