Question about Intel 3945ABG (WM3945AGM1WB) 802.11a/g/b Wireless Adapter

1 Answer

Lost signal My wifes brand new gateway computer keeps droping her wireless conection to our router. She has an internal wireless Intel 3945ABG card. Just to check the signal, I placed my 5 year old Dell, with and external Linksys Wireless G in it, for a few days and it never droped the signal. All her drivers are up to date. She is running a Gateway NX570X if that helps. Its still under warantee so if its a bum card, I can swap it out. Thanks

    Tried your soultion. I think the card ust gave up. I disabled it and plugged in an external wireless card and it worked fine. Called gatway customer service and they are sending out a replacement card. On a side note, their customer service is not too handy. They insisted that the part was built into the motherboard and could NOT be changed or removed. I told them they were wrong because i was holding the part in my hand. They STILL said that the part could not be removed and I informed them that I got instructions off their web site on HOW TO REMOVE THE PART. Then they got snippy with my wife and my darling lil 5 foot blond put them in their place! Hence... our part is on its way. Thats for the ideas guys.

check is to make sure you are NOT using "IEEE 802.1x authentication for this network."

You can find at setting under "Wireless Network Connection Properties" and then under "Authentication" tab of your network properties.

This particular authentication method is periodically logging you off the network and re-authenticating.

Check the adapter in device manager to make sure that windows is not shutting the adapter down to save power.

Cordless phones and wireless ethernet cards use overlapping frequencies.As a test, you can unplug the AC cords from all the cordless phones in the area and see if it helps.

Try going to the usb and the wireless adapter in device manager, properties. And make sure that the computer does not shut them off to save power.
Please let me know how you make out.

You should have only 1 wireless adapter, the other 1 is the ethernet adapter. If you experience low signal strength even after updating the drivers, you need to customize wireless settings on the router.
You need to change the wireless mode to "802.11b and 802.11g" or "802.11g", whatever you have in your router. If this is the same with all wireless networks, wherever you go, then its an issue with the adapter, you should get a replacement.

Is the internal wireless turned on? Depending on the computer, there may be a switch on the outside, and, there is also a software switch on some computers to turn the internal wireless on and off.

Intel 3945ABG - no connection

usually, on board wireless cards need to be enabled, or physically switched on via a toggle switch, or by pressing a button or a keyboard key (something like Fn + F2). Once it's enabled, a wireless light should turn on. If it appears to be enabled, you can further isolate the problem by checking if other wireless computers can see your router. If not, then the router probably needs to be configured properly.

Linksys N router drops signal

Its not dropping you because of the spectrums, it works on line of sight. If you are in a basement and your router is upstairs it has to go thru a floor and the strength is weakened. Go into your router and increase the signal strength. But you have to mod your firmware.

Here is a link to update your firmware.

Compatibility between linksys WRT54G Router and Intel PRO/Wireless 3945ABG Network Driver

from what you say, it sounds as if you have your wired and wireless card connected at the same time. This will confuse the router as it is trying to give two different ip addresses to the one pc, which it cannot do. If you are using the wireless adapter, make sure you dissable the wired adapter as the router will continually look for the wired ip address while allocating your wireless adapter causing instability. Next ensure you have a good clear signal from router to notebook as this can obviously cause problems. Lastly ensure that the wireless cards TCP/IP properties are set to obtain ip address automatically, especially if your router is DHCP enabled to allocate ip addresses automatically.
