When I'm using the wireless feature to hook up to my 802.11b router (which is connected to a cable modem), the CPU usage hovers around 25% (spiking up and down between 7% and 35%), even when I'm not doing anything on the computer and there are no network packets being sent or received.
Is this normal? Or do I have something set up wrong?
I've tried both WEP and no security (I couldn't get WPA-PSK to work), no difference in CPU usage. I also tried changing the channel on my router from 6 to 1, no difference. And I tried changing the roaming setting on my wireless driver to low, but that also didn't make a difference.
My computer is a Sony TX series TXN15P/B. It has a 1.2 Ghz Core Solo U1400 ULV processor.

Try updating the wireless drivers for your computer. Are you using the Windows wireless manager, or another management program for your wireless chip?
-
What Program are you using to manage your wireless connection? And what OS are you running, do you have all the updates for it?

I'm using Windows XP SP2. As far as I can tell, i'm using the default wireless connection manager which comes with Windows.
I have an Intel PRO/Wireless 3945BG Network Connection. I did download and install the latest driver from Sony. Intel has later drivers at their website, but they caution to not use it if you have OEM drivers, so I am reluctant to install it.
And now.. weirdly... Task Manager shows my CPU usage is back down to where it should be. What happened? I didn't change anything. Maybe the problem was radio interference?
I sure hate computers -
Same problem here. To be more specific, I encounter this problem ONLY when I make traffic on the network. For example, if I download at 10 KB/s, CPU Usage is about 15%, but if I download at 350-400 KB/s, it goes up to 60-70%.
I also experience a very weird problem: when there is network traffic, my mouse freezes for 2-3 seconds and Help & Support appears on the screen (as if I pressed F1 key). More than that, the Windows Time keeps staying behind (aproximately 2 minutes per hour) - excuse me if i expressed myself wrong, I don't speak English fluently.
I have a HP nx9000 notebook, I use Windows XP SP2 with all recent updates and the wireless card is LAN-Express IEEE 802.11b PCI Adapter (HP Wireless - as the driver software states). I tried with both drivers, the one provided by HP on their website and the one provided by Microsoft on Windows Update, but with no success. Also, I tried reinstalling Windows for 3 times, but there is the same problem.
Is it possible that all these are caused by a faulty CMOS battery ?
Wireless LAN causes high CPU usage
