inevitable if you are using analog modems. The time taken to establish the

modem link and the PPP connections may cause your client program (WWW browser,
|
|
etc.) to stop. This isn't common though. If this does happen, just retry that
|
|
Internet traffic request (say a WWW page) again and it should come up fine. You
|
|
can also try setting

<STRONG

kernel option to help with this initial setup.</P
