Need help Wireless Limmited/No connectivity

[NewsBot]

Sorry bout the abbreviations, but had to put something up there. Here's the situation.

 

How computers are connected to net:

-Cable connection from wall to cable modem.

-Cable modem to Linksys Wireless Router

-USB cord from wireless router to Personal Desktop computer (works fine)

-Dad's laptop via wireless network card to router (works fine)

-My laptop to wireless router via wireless network card (not working)

 

Weird details bout my laptop (it is a hnd-me-down from computer illiterate dad):

-Says there are 2 wireless connections

* -Wireless connection (1) IEEE 802.11b Wireless MiniPCI Card 7007 (must be a bult in wireless card)

* -Wireless connection (2) My Essentials G Notebook Card

- Both wireless cards (1) and (2) say that they have a strong signal, but limmited or no connectivity.

-In

the "support " tab of Wireless (1), it says this: "the problem has

occurred because the network did not assign a network address to the

computer."

-when click *details in that support tab, I get this:

* -Physical Address: *blah *(has one)

* -IP Address: blah (has one)

* -Subnet Mask: blah (has one)

* -Default Gateware: nothing there

* -DNS Server: Nothing There

* -WINS Server: Nothing there

-In

the "support " tab of Wireless (1), it says this: the problem has

occurred because the network did not assign a network address to the

computer.

 

Steps I have already tried:

-Made sure that it is set on "obtain IP address and DNS server automatically"

-Click

on "repair" in the wireless connection (1) properties->support tab

where it says "To restart the connection and try to establish full

connectivity, click repair.

-when I click repair, clears everything until I restart the computer and won't connect to the network at all.

-ran winsockxpfix...same thing happened

-disabled connection (1) tried everything; disabled connection (2), tried everything

-tried using both the wndows wireless software and the software provided by the wirelss card

 

So basically I feel like I am banging my head against the wall here. *Any suggestions would be appreciated.

 

How do I find what type of security is on the router? And how do I find

out if there s a password on the network? My mom cannot remember.

 

Also,

since my mom's networking is run through USB cord, in her networks, it

says LAN line connection and nothing else. Does this mean that the

wireless network is set up through my Dad's Laptop? If not, where do I

find it on my mom's computer?
