Can't Connect Two Laptops to Same Home Network
I have a Linksys WRT54GS wireless router at home. I recently got a new laptop, and I tried to use the wireless feature on my new laptop. All of a sudden both my laptop and my wife's laptop could not connect to the internet, and the Orange "Cisco" light was slowly blinking on and off.
I think it might be because my new laptop said my wife's laptop and my new laptop we had the same IP address. WTF?! We're using the same wireless point!
I have my laptop's wireless function turned off right now. How can I connect both computers?
Also, when I try to set up and encrypt my home network, I tried WPA Personal, what shared key do I put in for the WPA Shared Key? I wrote down a 26 alpha-numeric key before, and when I do this, it immediately kicks me off the network.
I can deal with the security, but I want to solve problem #1, which is both computers having the same IP address.

make sure you don't have a static IP assigned to one of the PCs or if you do that it's outside of the DHCP range.
make sure you DHCP range isn't too small, if its set to only 1 IP address then it will only give out one, though I've never seen a router do that. Me thinks your router sucks and you need a new one or were you messing around with the settings of the router and you messed it up and don't know how to fix it?

I went to http://192.168.1.1. At the Setup tab, what should I have as the Maximum number of DCHP addresses? Right now it's set at 50? Maybe 10?

50 is normal and plenty. Actually my friend is complaining of the same thing happening to her router. I'll probably have to go over there and look at it, I've never dealt with this problem but it seems like a faulty router. I don't think there's a setting you can change that will fix this, this isn't a feature of the router.
The fact that it's giving both PCs the same IP address means to me that the router has gone haywire.

How do I check to see if I have a static IP address then? And why the hell am I getting a problem now, seeing that I had a third fucking laptop that worked fine on the Internet? Why is it that this new laptop makes everything go haywire?

You'd probably know already because it's something you have to do manually.

OK, so if I had to set up a static IP address manually, it's safe to frickin' assume I didn't do that. I had two laptops connected to the internet before. Why now that I decided to add a third laptop am I having problems?
How do I fix it using http://192.168.1.1 so all laptops work well and can access the Internet at the same time.

Make sure each laptop is obtaining their IP addresses automatically rather than demanding a specific IP number. This ensures that the router is the boss.

There are a couple of different settings to look for. 1 is the maximum number of Connections allowed. The other was (iirc) the range of IP addresses to use.
As long those are both large enough to accomodate all your PC's (i.e. at least 3 connections and 3 IP addresses), it's probably not the issue.
Don't forget that you have to count not only wireless connections, but any PC with a wired connection as well.

We had the same (or similar) router.

Sounds like something with the other laptop, not the router.

No. I'm just saying your router seems to work like it's supposed UNTIL the other laptop is connected.
You've checked the router settings and if all is well, then maybe it's the laptop itself.
What happens if you use a wired connection for the "rogue" laptop? Does that work?
Is the problem laptop set up to share it's internet connection? If so, disable that.
Otherwise,

Default gateway is fine. Make sure both laptops are automatically being assigned rather than having a predetermined ip address.

we had the same router and it did the same thing with my Wii and my laptop..... you could attach 2 wireless devices and then after that no more. The end solution was to replace the router with a better one. Have not had any issues since it's replacement. I even went as far as to hard reset the device and reload the firmware.....

As far as they're concerned, you're only using one IP. Your router is assigning private IPs on your network.
