signal strength = excellent but no connection?

Recently I reinstalled windows, before that my internet (and my wireless network) where working flawlessly. However, ever since I reinstalled windows (today), I either can't connect to my home network or when I do connect (by manually imputing the ip/dns/gate addresses) I won't receive any data (even though it registers that the data is being sent).

after I input the addresses, manually

the details of the network connection, and the source of my splitting headache

my wireless card

For TCP/IP all I know how to do is set the ip/gateway/dns. I'm don't know how to set up DHCP >_<

edit: I did a ping, the only thing that didn't respond was the DHCP server (though I'm not sure if that has any relevance to this)

second edit: I set it to auto detect the TCP/IP and it didn't detect the gateway or the DNS settings

how do I enable mac filtering and to reset the router I have to disconnect/reconnect it, right?

my router doesn't have anything like that. Its a 2wire gateway, all it has is 3 lights (power, broadband link, and local network) and 4 ports (power, telephone, ethernet, and USB -which is unused-)

I still don't understand how to reset it.

Also, the 2wire is already connected to the host pc through ethernet (the one I'm having the problem with is the wireless laptop)

ok, I reset it. But I still can't connect

lol, turns out I just needed to make a new network >_<

basically I needed to change the name/wireless channel/encryption. Which created a new network that I was able to connect to

from the questions and comments I've made here...I'm surprised that you think I know the difference between the two >_<
