No wireless even with strong signal

Specs: Windows XP SP3
Hi. A customer of mine has an antenna on his roof that he uses to get wireless. (He lives in the middle of nowhere and pays someone to share their wireless) The signal from the antenna is piped into his Dell desktop computer via a coaxial cable. That works great, but he also has a Gateway laptop that his wife uses. There's a crossover cable that runs from his desktop to a Belkin wireless router. Now, the laptop sees the signal from the router, and it can actually log into the router (192.168.2.1). The signal is strong, too, and the Internet and wireless lights on the router are solid green. But every once in a while, even though Windows says it's connected, the laptop stops loading web pages and it can't ping anything beyond the router. There's only one other wireless network in the area, and it has almost no signal. He says he's gotten it to work by just rebooting the desktop computer. I got it to work today by disabling and re-enabling the connection inside the desktop. Rebooting the router doesn't work. Changing the channel doesn't work, either. It has no encryption. He has two connections listed in the Network Connections folder on the desktop. One is wired and the other is wireless. I think the wired one is the connection to the router. One of them uses a static IP -- I think that's from the antenna on the roof. He actually expects me to fix this problem. His computer is acting weird (really slow, etc.) so I was thinking of re-installing Windows. Any other ideas? Thanks for any help.

That sounds like a job I would walk away from. Too much liability for you and not enough pay.

Concerning the laptop and wireless router. Unless that router can bridge to the other wireless router, its a dead end. Most wireless routers are just an access point that converts the incoming cable or dsl into a two way wireless signal.

"the Internet and wireless lights on the router are solid green."

No mention of dsl or cable. If this router is hooked up then why is the guy using someone elses wireless?

This post is not making sense.

Thanks for the reply. He uses an antenna on his roof to pick up a distant wireless signal from someone he pays for Internet. The coaxial cable from the roof gives his desktop Internet access, and he passes the signal off to the router. So, he's using the router in his house as a repeater for the laptop. So, there's a coaxial cable connected to his desktop and there's a crossover cable connecting the router to the desktop. Does that make sense? You mentioned bridging. Should I bridge the wireless and wired connections in the "Network Connections" folder on the desktop?

Crossover goes from a lan port on the belkin to a lan port on his desktop? That would be the correct config. You can bridge the two interfaces on the desktop or engage ICS [internet connection sharing] between them.

What is setup now?

Make sure the desktops firewall has a host entry for the laptop and that it is trusted.

ok. I will take a closer look tomorrow. Right now, the crossover cable is connected to the "Internet" jack on the router. I'll try messing with the ICS settings and bridging the connection.
