Wireless Laptop Setup

[autowizz]

I have a friend who wants to have wireless access setup in his motorhome.

He has a wireless Linksys router and a laptop with the centrino stuff.

He has a wifi modem from cingular hooked into the laptop.

What he is looking to accomplish is can he leave the laptop connected to the internet and allow other people that have laptops with wireless cards in them to access the internet thru his setup while in the motorhome??

Any help would be appreciated.

Thanks

you will need to connect the linksys router (in the WAN port) to the modem via the ethernet cable. find how to configure the router from its manual, set your new security and encryption settings (WPA-PSK is recomended, unless you want someone you dont want leeching off your service), LAN settings and WLAN settings and dont forget the passwords for the ISP connection...

with the laptop(s) turn on the wifi adapter, find the router on it and set exactly the passkey, and any other unique info you set on the router

How do you connect the router to the modem in the laptop?

It is just a card with a antenna sticking out of it. There is a ethernet port in the laptop too??

..and allow other people that have laptops with wireless cards in them to access the internet thru his setup

effectively, this is creating a local hotspot for his friends and neighbors.
yes you CAN, just leave all the encryption OFF and you have a open network.
Beware that an open network exposes EVERYONE to everything.
Make sure everyone has an active firewall and that File/Print sharing is disabled!

if the modem for the ISP is on a PCMCIA card, then you can either share it using ICS (not recomended, laptop will have to be on all the time to access the net) or ask the ISP if they can give you a modem that has an ethernet port (trust me.. stress this one to them or they may give u a USB one.. you dont want USB, but if theres both USB and Ethernet ports then thats ok..) then with your laptop, enable its wifi adaptor (modern ones will have them inbuilt, older laptops will need an adapter via USB or PCMCIA)

on a FYI note, yes all modern laptops (post 2000) should have an ethernet port as standard....
