try pinging the address of the computer that's physically connected to your router.
In both computers, go to run,
type cmd
enter
in command prompt type ipconfig
enter
this will give you the addresses of your computers.
you should be on the same network on your wireless as if you were plugged via the cat5 cable.
type
ping x.x.x.x
the "x" is the numbers you get from ipconfig
ex: ping 192.168.0.1
there's a possibility your wireless computer is on another network by accident.
check to see that the SSID on your laptop is the same as on your router and that you're router is not using a default SSID.
Also, try starting from scratch. No encryption, no mac filtering, no anything. Start bare, But change the SSID so you can be sure that it's yours.
Erase all wireless SSID's that were recorded in your laptop. That way, when you look for your SSID, it will be the first one on the list to be searched for by windows. Once you get it working, enable all securities you want.
I have a Netgear 624 wireless router hooked up to my desktop with a ethernet cable. I also have an IBM laptop that has built-in wireless. I can access the internet from either computer anytime my cable modem is powered. However, my home network is a different story. My laptop normally is in a different room that also has an ethernet cable connection that plugs into the router. So I can plug into the laptop IF I want to with hardwire. Normally, I don't as I take the laptop to other parts of the house.
When the laptop is plugged into the network with the ethernet cable, I have full sharing of all shared folders on either computer. However, if I unplug the ethernet cable, I lose this ability although I can still access the internet through the same router that my ethernet cable run through.
The computers are in the same workgroup and all the other options have been checked several times. Even with all firewalls off except the hard firewall in the router, I still can't access my shared folders in wireless mode only.
Both computers are running Windows XP with SP2 installed. Anyone have any ideas about correcting this problem? From reading other "Subjects", this problem seems to be more common than not.
