AUTHENTICATION PHASE (LOGGING IN)

Almost all ISPs require you to identify yourself by logging in after the LCP phase is complete.

What happens

Possible problems and solutions

The Nokia A032 will send the user name and
password which you have previously configured.

If the login is accepted you will see an

accept

message in the PPP log.

If the login is not accepted, you will either see a
reject message in the PPP log, or the line will just
be dropped by the ISP. If your password is not
accepted there may be several causes

including:

Incorrect capitalization

With most ISPs, the password open is not
considered the same as Open.

Missing prefix

Sometimes the username needs to be prefixed
with a network identifier. For example, an ISP
called Fastnet Inc. might require the user name to
be prefixed with the string FSN/. Check with your
ISP.

Login script required

The ISP does not accept logging in via PPP and
requires the use of a login script. See Setting a
logon script
of the printed Nokia A032 Wireless
LAN Access Point User Guide
or the
A032_User_Guide.pdf file.

5.4 IPCP

PHASE

The ISP agrees or assigns the IP address information you will use on its network.

What happens

Possible problems and solutions

In most cases, the ISP will send the IP address
information to the Nokia A032 to use as its
external IP address (see Appendix E of the
Printed Nokia A032 Wireless LAN Access Point
User Guide
or the A032_User_Guide.pdf file).
The negotiation during this phase is done in a
similar way to the LCP negotiation. However, in
this case the protocol is called IP Configuration
Protocol
(IPCP).

If the ISP fails at this point of the negotiation:-....

you may have programmed incorrect values
in the Nokia A032, or

the ISP is unable to provide IP information
automatically.
