Help. Laptop cannot connect to wireless router

My setup:
Desktop running XP Pro (not SP2)
Laptop running XP Pro (not SP2)

Netgear 814 - 802.11b wireless router. No WEP, no access conrol,
nothing enabled.

Desktop connects to router Ethernet port, no problem in connecting to
internet

Laptop connects to router using TwinMOS 802.11b card. Installed the
correct driver.

When laptop is powered on, it shows me a list of available wireless
networks (no other network shows up). I choose my network, check the
box that says "connect even if the connection is not secure, no WEP
etc.," and click on Connect, nothing happens I see a message at
laptop's status bar saying "no network available" but at the same time
my desktop (or router) loses internet connection. I have to power
off/on the router to restore internet access. This is driving me nuts.
What am I doing wrong?

I have been trying to get this working for nearly a week. Yesterday I
had my laptop running, for some reason I powered off/on my cablem modem
and the router. When the router came on, my laptop picked up the signal
and connected to the wireless network and both computers could access
internet. Then I rebooted my laptop and I was back to square one where
the laptop was unable to connect to the wireless network. Any ideas?
Should I get same brand router and card?

Thanks

How did you set up the connection? First, is the workgroup name the
same as you have for the wired computer? Second, did you run the
wireless wizard? I've found that this is often required to fix the
parameters in the registry for a new wireless connection. If you open
the TCP/IP properties, set the default gateway 192.168.0.1 or whatever
the router address is, and also set it for the default DNS server.
Enable NetBIOS over TCP/IP, which is the middle of the three choices.
Enter your network IP in the trusted zone of your firewall. Broadcast
SSID; many wireless cards will fail to connect if SSID is not broadcast.
In the Advanced tab, TCP/IP filtering, check that Permit All is selected
for all three ports/protocols.

Then when you get a reliable connection change the IP block for your
network, 192.168.XYZ. where XYZ is any number 000-255; change the
default router login name and password; enable MAC address filtering,
and enable WEP.
