Question about Intel PRO/Wireless 3945ABG Network Connection (WM3945AGMW1WB)

1 Answer

Intel Pro Wireless 3945abg not connecting to higher speed DSL

I am running Windows XP Home Addition and have an Intel Pro Wireless 3945ABG Network Card on my Dell Inspiron E1705

I just upgraded my DSL service from 1.5Mbps to 12Mbps with Qwest and received a free Netopia 3347-02 Modem/Router. It is installed and working however when using Wireless it is coming in just about 1.6Mbps and when switched to Ethernet it is just under 12Mbps. I can't figure out what needs to be changed to allow for the full 12Mbps. The Laptop is two feet away from the Modem/Router

I have another Laptop in the house, an IBM with an Intel Pro Wireless 2200 card and it is showing the same slow speed in Wireless mode.

Any thoughts or ideas??

Thanks a lot!!!
Dave

    Thanks latinmcgyver for your comment. I have run a TCP/IP analyzer and adjusted parameters. I'm running on my Ethernet rather than wireless and getting about 9meg. When on Wireless alone, I'm getting about 5meg which is an improvement over previous speeds. Thanks again!!

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

Vista Wireless Problem: Intel Pro/Wireless 3945ABG


Hi Pete,

You sound like you know what you're doing, so forgive me if these suggestions seem foolish or patronising..
Does your laptop have a wireless button?

When you go to Internet Options and click the Connections tab, have you checked 'Never Dial a Connection'? This is essential..
I have exactly the same ethernet card and network adaptor, but haven't had any problems, and we have 2 laptops and 2 pc's here all detecting our router okay so..
It's definitely not MAC filtering on the router, as you would still see the network in your list..
I can only suggest uninstalling the Intel Pro Wireless driver and downloading a fresh one from here.
That'll reset default settings at least..
Hope this helps
Let me know how you get on.. If I face this problem I want to know how to fix it too!

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Code 10 usually means the device driver is not compatible, outdated or corrupt.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

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

Hope this helps

Code 10, intel pro/wireless


You can try updating the drivers for that wireless adapter. If the same happens, you can try to uninstall it completely then reinstall it with the updated drivers.

You can also try to install it on a different slot or a different laptop to test the connection.

If you have other problems, go ahead and press the ask button and i'll answer it for you.
