Re: [wlug] Wireless TCP/IP

Hi Bill, It sounds like you're nearly there and your commands look mostly correct. A few suggestions and example commands * You didn't mention what you set the ESSID to on the windows machine, you might want to verify that it is the same as the Linux machine. There are 3 settings that must match for the link to be successfully established at the wireless layer. They are Mode, Channel and Essid, in your case it seems that they should be set to Ad-Hoc, 6, "deb1" The following commands would achieve this setup. iwconfig eth1 mode Ad-Hoc iwconfig eth1 channel 6 iwconfig eth1 essid "deb1" * Once you are sure that the wireless layer is up correctly you can configure the IP addresses. Your machine already has a default gateway out sl0, so for now I would suggest that you don't try and setup a default gw over the wireless. I would suggest you use the following command to configure the laptop ifconfig eth1 192.168.0.5 netmask 255.255.255.0 broadcast 192.168.0.255 At this point (assuming the windows machine is correctly setup) you should be able to ping 192.168.0.1 from the linux machine and get some replies. If you can't please reply with the output of the following commands iwconfig eth1 route -n ifconfig eth1 NOTE: It's important that you setup the interface in the following steps 1) Make sure the interface (eth1) is down 2) Execute the iwconfig commands 3) Execute the ifconfig command (will Add IP and bring interface up) 4) Perform tests This order is crucial because the new network settings are not written to the wireless card until you bring the interface up (via the ifconfig command).
