Question about Linksys Wireless-G WRT54G Router

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

We have configured linksys WRT54G Router at our home and two laptops(XP and Vista) are connecting fine with the router but the moment i try to connect lennovo 3000(Y500) which is having Intel PRO/Wireless 3945ABG Network Driver(bought 15 days back) it connects fine for the first time but after a minute or so the router power start fluctuating continuosly. Again when I disable the wireless network in lennovo 3000(Y500), power of router get stabilized on its own. So the problem is whenever i try to connect the lennovo machine having Intel PRO/Wireless 3945ABG Network Driver fluctuation of router starts and when i disable wireless connection, router works fine. I went through some forums and changed the power management properties in Intel PRO/Wireless 3945ABG Network Driver to the highest but it did not help me. Please help me regarding this. If possible please tell me do i need to upgrade the firmware of router, if it is so tell me how to do it. Thanks in advance.

    Thanks for the reply sandrew but this is not the case, I mean I have not connected wired and wireless at the same time.

    I just enabled the wireless network of the lenovo machine and router's intermittent behaviour starts though it was working fine on other laptops before enabling lenovo's wireless connection.

    Now, about the signal part other laptops are working fine even in the distance of 10-15 ft but lenovo is not working even in one or two ft distance.

    Regarding your last point, it is set on automatic obtain of ip address only.

    Thanks for your concern but it did not solve my problem.

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.

    just another thing to check is that maybe your router is set at 54MBPS transfer rate and the pc is set at a faster transfer rate e.g 108MBPS or 125MBPS, also check that the network card is set at the correct A, B or G configuration as your router will be set at 'G'

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.

Intel ProSet Wifi software can't connect to network


You need to manually add the network using your intel pro set utility. Or just switch to wzc.(wireless zero configuration). How to do it? just click start - go to run - type in services.msc - then look for wireless zero configuration on the list - right click on it then click start.
Then look for the wireless network connection icon on the system tray (that's in the bottom right hand corner of your screen). right click on it then select view available wireless network.

note: if you'll be getting the message "windows could not configure..." click change the order of preferred networks(that's in the same window where you're getting that message) then check the box that says "use windows to configure my wireless network settings" then click ok. after that go back to view available wireless networks then you should see your network now.

note: if you're using a corporate laptop where you don't have admin rights on it you need to use the intel pro

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?
8f45b35.jpg

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

Intel Pro Wireless 2200BG problem or Linksys BEFW11S4 problem?


I had the same problem. If you are using the latest driver for your intel 2200BG (9.0.4.7). Try to roll back to a previous version. It solved my problems with being unable to connect to a Linksys BEFW11 router running WEP64.

I am now running driver version 9.0.1.9
