high cpu usage - dlink dwl-g510

[freightcar]

i am having strange problem with my dlink dwl-g510

everytime i use wifi my cpu usage jumps to 100% an the pc is more less
unusable. when i disable the card the load will get to normal (2-10 %)
i noticed one thing - when i remove the antenna everything is normal
(except the wifi signal is obviously lower). i installed the card in another
pc and it behaved the same way. i called dlink several times - they keep
saying that the problem in on my side (ie win problem, low memory[i have 512
mb] etc), and referring me to higher levels (currently waiting for L3 to get
back)

tHanks for all ideas

forgot to mention that every other time I am not able to connect to my
router at all

Try a different wireless adapter.

freightcar - Try this idea. Actually you almost had it yourself. This worked for me and another guy with the same problem!

If you have high CPU usage with the D-Link DWL G510, try this simple test:

Open Device Manager and monitor CPU usage. If it is running high, normally you could check the Processes to see which ones were using the CPU. But, if the System Idle Process is running near 99%, that means no other processes are using it. This scenario indicates that you may only have an antenna problem.

I had high CPU usage of around 20% whenever I connected using my d-link dwl-g510 wireless adapter. I tried many other fixes with no luck. In my case, I had wires from the mouse, keyboard, and monitor draped around the wireless antenna. When I moved the wires away, my CPU usage dropped to 1-2%. However, when I moved the antenna down toward the wooden desk, the CPU went back up to 20%. So, it seems that any antenna interference is bad. But it's an easy fix!

Also, the Device Manager is a very handy gauge to see where to point the antenna. Just keep an eye on the CPU usage data while you move it around. In my case, just a small 1 inch change made all the difference. I hope this helps others out there.

Conclusion:

After I added two USB Hard Drives to the computer, I had too many cables around the little antenna to get good reception. I could not find a position that would work. So, I did some research and bought this antenna.

Just in case the above link stops working, the antenna I bought is the
D-Link 7dBi Omni-Directional Antenna

It screws into the wireless card after removing the original antenna. It has a shielded cable to eliminate interference and it fixed all my problems. It works great.
