Wireless Router and Desktops

I am helping my friend setup a wireless router at his home. We are not doing a wireless network (I don't think). We just want the computers to connect to the internet wirelessly.

What he has: 3 desktops and one laptop.

He used to have an old wireless router hooked up to one of the desktops. He decided to upgrade the wireless router to a "stronger" one. Before we switched the wireless router, the two desktops were able to connect to the internet using the wireless service. Each desktop has a wireless card installed. The desktops are all Dell PCs running Windows XP.

Since we setup the new router only the desktop that is hardwired and the laptop can connect to the internet. The laptop is connecting wirelessly.

The other 2 desktops are not connecting. One of the desktops doesn't even recognize the new router. When I search for a list of available networks, the router doesn't show up. I tried to add it manually, but it still doesn't show up.

On the other desktop, the new wireless router shows up, but it won't connect.

Any ideas as to what to do or what the problem could be.

Could it be a driver issue, compatibility issue . . . ?

Thanks in advance for any and all help.

That is the two I am working on for now. The third PC I am going to fix first. But hopefully this will give me an idea as to what the problem is.

On this PC (Desktop PC2), it does not pick up the router at all.

 

Well, this machine shows a good connection to a wireless router that is connected to Comcast. Is that your router? If so, you have a connection to it.

Try these simple tests.

Start, Run, CMD to open a command prompt:

PING 216.109.112.135

PING yahoo.com

Right click in the command window and choose Select All, then hit Enter.

This computer can get online, but it is picking up the wireless signal from another router. I think the neighbors. We want to pick up the router in their house.

 

I suspect that the router you're trying to connect to has the SSID broadcast disabled. First step is to check the configuration of the router.

 

a "stronger router".
