    Having problems setting up ad hoc network.

    I'm trying to set up an ad hoc network so I can connect to my carputer from work while it's parked..

    I am able to get connected to it but I can't ping it for some reason..

    I don't have a firewall on either machine. Any ideas?

    Thanks!

    What address are you using to ping? I've always had issues with Ad-hoc with regard to reliability. The standard just doesn't seem to be very mature unless you know what you are doing.

    Here's what I usually do. Go into Network Connections and go to properties for the wireless adapter. On both machines, set the IP manually (192.168.0.x or whatever suits you), and subnet of 255.255.255.0. On one machine, leave default gateway and DNS servers blank. On the other machine, set those fields to the IP of the other computer.

    I eventually realized that 80% of the time it took to establish a connection was because of IP. It's a lot more forgiving when set manually. Let me know if this improves your condition.

    The reason it takes so long if your using DHCP is because if your not running a DHCP server on the PC your connecting to then the client won't get an IP address.

    What I do is go into the wireless network connection properties, tcp/ip properties, alternate configuration. There I assign an IP address of 192.168.40.5 on machine "A" with a subnet of 255.255.255.0. Then on machine "B" I do the same thing except assign it 192.168.40.7.

    This way.. When I want to connect to a WAP I don't have to go back in and change the settings to DHCP so it can connect to it.

    This way works and I can get connected I just can't ping for some reason.

    So both machines show 'Connected' with an IP?

    Yes, both machines show connected and use the IP's I configured in the "alternate configuration."

    I just tested that config and it works fine, although the IP still takes awhile to pop up. But they ping fine, and as soon as its connected. Are you pinging by IP address instead of computer name? Check again to make sure they are on the same subnet and the first three fields in the IP are the same.

    Yes, I ping by IP address. Yea, I know it works. I had that setup on two laptops and it worked fine. Just can't get it to work with carputer and laptop.

    Both using the same encryption/password? Try retyping it. All proper protocols installed and checked in the adapter properties? I'm just throwing out ideas now. If both cards show strong, unfaltering signal then I'm a bit stumped.

    As a test you might want to disable your other network adapters, then connect and test ping. I've had issues like that before...
