Problem with Wireless LAN on D600

Question

I have a DELL Latitude D600 with Intel(R) Pro/2100 Wireless LAN installed.
My home has a cable connection that is connected to LINKSYS BEFW11S4 Wireless Router.

This router server 1 PC with wired LAN, and I also managed to get it connected to my D600 via wired LAN. However, when I tried to switch to wirelan LAN on my D600, I encountered problem.

From the status bar, I can see that the signal strength was excellent. The network status was active, but I see many packets being sent but none was received. Hence, I was not able to surf any websites. What exactly is happening? Please help me.

Below is my printout of "ipconfig/all"

IP Address. . . . . . . . . . . . : 192.168.1.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 218.186.16.1

The "Default Gateway" is somehow getting set to an address that's not on the same network as the Wireless LAN adapter. The correct setting for the Default Gateway should be 192.168.1.1, the address of the BEFW11S4.

The incorrect setting's most likely coming from a "hardwired" gateway setting in the TCP/IP properties of the 2100 wireless adapter.

Go to your DOS prompt and enter the following:

ipconfig /release "Ethernet adapter Wireless LAN"

then the following:

ipconfig /renew "Ethernet adapter Wireless LAN"

This should renew the your ip and fix your problem.

I have exactly the same problem with 2 D600s we have just bought. Wireless appear to pick up an ip address from the router but I can't ping any other IPs on the same network.

My ipconfig is below.

The release command did not fix my problem!

Any ideas anyone?

Are you sure the subnet mask is correct for the actual network topology? I've been trying to figure out what the network actually looks like, and if the subnet mask (255.255.240.0, or /20) is right, this is a supernetted Class C network whose base address is 192.168.128.0, with a range of addresses from 192.168.128.01 to 192.168.143.254, and a broadcast address of 192.168.143.255. Yet for the two IP assignments on the D600 you list, the default gateways are different. So the network doesn't look like I think it does. What address range does the network span, or are there several networks interconnected by routers?

If you "tracert" from the D600's wireless interface to another machine, what happens? Is there a "network unreachable" error generated by something? What does the routing table look like on one of the D600's? ("netstat -r").

"ipconfig /release" will only correct problems if the topology has changed, or if there were "hardwired" local entries that have been removed on the machine having problems. I assume neither of those is true in your case.

I used this network calculator in attempting to figure out the topology.
