Wireless connection problem

Hi there, I have a notebook Dell with wireless board Intel(R) PRO/Wireless 3945ABG Network Connection. We have an access point in our office connected to the router and all other notebook access it without problem. My notebook detects the access point but at the time to connect, itkeeps trying to connect with no luck. Can it be a problem with driver? I have downloaded a new version but same result. If you can give me any help would be greatly apreciated. Regards, Antonio

    Hi, thanks for your time. My OS is XP Professional. I have tried to add network manually. i tried the manual diagnostic tool (of intel wireless manager program) and appears to be an "association problem".. the SSID name is ok and i think might be a problem of mac address not listed in the AP... anyone has other ideas?
    Thanks, Antonio

    yes... my doubt is that there is a MAC addres filter, but unfortunately our branch has not the power to access change that. Is there a way for me to be sure that the prolem is this one? Thanks

What is the OS of your PC? Try to add the wireless connection manually on your PC and enter the wireless security.

    What is the operating system of your PC? Do you have wireless security enabled? Try to add the network manually on your PC and enter the ssid and secuity if any.

    Are you saying that there is a MAC address filter on the router? If so you have to add the mac address of your laptop to the router. If you're not sure with that, you can also try assigning a static IP on your laptop, maybe it's having a hard time grabbing an ip from the router.

    The only way to check this is by isolating the problem. If you can connect to your neighbor's network on that same location then we can say that we don't have a problem with your laptop and the other thing is if you can bring a different laptop or wireless device on that location you can try if that will work. On that way you can isolate the problem.

I had usualy solved mysterious problems with other intel PRO wireless cards not authenticating, loosing signal, etc, by simply upgrading to the latest intel drivers.
Also using the Intel connection manager instead of the windows or Dell/other notebook manfucaturer's product is far more reliable.
Hope this helps.

Cannot connect wireless


My best suggestion is not to use the Intel wireless manager. Please go into the wireless manager and take off the "check mark" where it says the Intel Manager manages the wireless card.  This will disable the Intel wireless manager from managing your wireless card and give control back to Windows.
-Right-click "Recycle Bin" and choose "Explore"
-Right-click "My Network Places" and choose "Properties"
-Right-click on wireless network (should only be 1, maybe 2) and choose "View available wireless networks"
-Click on the wireless name from the list that belongs to your office Access point.
-If it needs a key, enter the key when prompted (it will ask you to enter it twice, one for each line).
-Once you complete this step, you should have wireless access once again.
-Intel will keep prompting you if you'd like for it to manager your wireless, I suggest you ignore this message from this point forward and only use the Windows wireless manager (built-into all Windows OS). :)

If you have security set-up on your router, you need to set it up on your wireless access point.

Intel PRO/Wireless 3945ABG Network Connection code 10


Hi,
Code 10 usually means the device driver is not compatible, outdated or corrupt.

Try uninstalling the wireless device again and then reinstall using the latest driver available from:

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=2259&OSFullName=Windows+Vista*+Home+Premium%2C+32-bit+version&lang=eng&strOSs=153&submit=Go!

NB If you're running XP, use the second one.

Hope this helps
