Home Networking Question

Hey all, got a question for you. I have a D-link router and 4 computers in my network. Computer 1 is connected directly to the wireless router, no problems. Computer 2 is connected wirelessly to the network and was able to obtain the DHCP lease just fine. No extra configuration and no problems. Computers 3 and 4 are connected wirelessly and were able to detect the wireless network without issue, almost immediately. However, they are not obtaining their DHCP lease (IP, Gateway, DNS information). I have had to configure computer 3 and 4 with that information for them to be able to connect to the Internet.

Any ideas why that is? They are all the same brand of NIC (D-Link). I know they all work, because they connect after I configure, I just don't know why they won't obtain their configuration settings. Thanks in advance.

Are you running any software firewalls on any of the systems?

Nope, no firewalls of anykind.

Check to make sure that your router is configured with a pool of more than one IP address. I've also seen wireless connections 'connect' but fail to receive an address if your WEP/WPA key is incorrect, but this would also keep you from connecting with manual settings, so that can't be it.

Are Computer 2, 3, and 4 all on the same OS? Same service pack?

My DHCP pool is 100 to 199. Not using any encryption in this environment.

OS should be like this:

1 - XP Pro SP2 (also worked with SP1)
2 - XP Home SP2 (also worked with SP1)
3 - XP Pro SP1
4 - XP Home Sp1

UPDATE: So I updated the firmware as just a troubleshooting step and it works now. I didn't see anything in the release notes for the firmware about it, but oh well.

Yea, it's amazing the problems you will see with shipping firmware. Updating the firmware is always one of the first things I do with a device. Even Cisco stuff.
