I have a new Dell Inspiron E1505 Laptop with Intel Wireless Adapter. I am presently connected with a DSL Home Network with my ISP. I am planning to go on my first trip with my laptop. I plan to use my same ISP. I have several questions I hope you can answer.

1) Do I need to take my router that is connected to my Network?
2) Will my network work at all?
3) Where I am going previously I used wired dial-up connections, will I still need to do wired instead of wireless?
4) What will I usually pick up with the wireless connection?

I have never used a wireless before. I appreciate any help you can give me.

Thanks for your help,
