Help needed

[Satyam]

Dear list,
I have problems in using Ubuntu 6.10  with Orca.
1. When I tried to use  Orca with Firefox, I am not able to read full page
contents. Only some part of the page is read.
How I can read Headings, Tables and lists?
2. How to setup internet connections?
I found that in administration menu There is an option to connect to
internet.
It is asking for IP address but I use dynamic addressing scheme. My service
provider gave  me User name and Password.

Please help me in this regard.
Hope to hear from you.
Satyam.
