Problem with wireless network on DHCP

Question

Hi, I'm posting my message again as it got deleted. I have an E1505 which has an intel 3945ABG card. I am unable to connect to the wireless n/w if i use the automatic IP address option (DHCP). If I manually configured the IP addreess, then I can connect without a problem. Dont know why this happens? My router is configured to allow addresses (192.168.0.100 to 199) in DHCP server settings. I have tried connecting with and without security (WEP) also. This doesnt help either. Downloading the latest driver for my card and firmware update for the router also didnt help. Two of my friends having the exact same config. of laptops (same wireless card) are able to connect without a problem to the same router! Any suggestions? Thanks in advance.

Go to Services again and make sure the IPSEC Services is started and set to automatically start.   Steve

Go to Start > Run and type services.msc then hit the Enter key.  Find the DHCP Client service and make sure it is started and set to start automatically.   Steve

Hi, I checked the DHCP client service, It is enabled and set for 'Automatically'.

I did try with the ethernet connection and it works fine with automatically getting the IP address.

That seems to indicate that it is strictly a problem with your wireless network device not a problem with Windows.  I would suggest uninstalling the wireless card, rebooting, and reinstalling the latest drivers for the card.   Steve

As a troubleshooting step, see if you can connect with a wired connection to the router with ethernet network card set to obtain an IP address automatically.  Report back what you find.   Steve

I'm out of ideas.  It's either a bad network card or something obscure messed up in Windows.  I'll think about it overnight, but otherwise I'm stumped.   Steve

Is the Intel ProSet Utility managing your wireless network or is Windows managing?  If you use the one you are not currently using, does DHCP work?   Steve

Tried with both, windows manager and intel pro wireless connection manager but the same problem exists.

Hi

I have done that multiple times. I downloaded the latest drivers, once from the dell website and the other time from the intel website. The problem doesnt seem to go away.
One observation is that it connects to the network on DHCP intermittently. Sometimes, after a reboot, it manages to connect to the network...but this behavior is also not consistent.

Tried with both, the windows manager and intel pro wireless utility but the problem still persists.

Hmmm..........same here...even the tech support tried remote debug on my machine, but cudnt get it runnin' :( I have also tried searching other forums fro known issues but to no avail!

If your friends have the same laptops and the same network cards. Then I would suggest swapping the network cards with one of known good computers. If the issue follows the card then you know you have a bad one if you still have the same issue with a known good card then you know it is a software issue. If your friend will allow you to do this.
