My new network card lights up, but Windows doesn't find it. Why?If a new network card fails to be detected when plugged into a Windows XP,

hi my system lan card is disable automaticaly plz tell me the solution.

Put new Windows XP Professional on my laptop recently but before i did it I downloaded all drivers from Packard Bell website that i would need 2 re-install.Problem is,iv installed da drivers for my network card but stil says no network adapter found wen i try 2 connect 2 internet!Any ideas what i cud do???

I have a D-Link DWL-G510. When I first installed it, it worked fine because I installed the software driver before I installed the adapter in the PCI slot. Some time after, I had a problem with my computer and had to re-install Windows. The problem is that I forgot to retrieve the adapter before re-installing Windows. Now the adapter doesn't work. Windows XP recognizes it but won't start it. I tried uninstalling the driver and then re-installing it without the adapter in the slot (I even cleaned up the registry) but it still doesn't work. I'm pretty dumb-founded, I do not know what to do. I would be very thankful if you'd tell me what my options are...

The usual good methodical approach. I am about to network two computers in a home environment so any article on the subject is of interest.

Marc:
I have exactly the same problem. Card first worked, then I had to reinstall windows and now the card doesn't work. Did you find a solution?

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.

I just installed window Vista. Vista could not find network adapters (NIC) and sound card. I did download drivers for both of these, but were still in vain. Do you have any idea with these problems?

Conclusion of my story one post above:

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.

I am using an old Dell laptop running Windows 98SE. Can I use a wireless card with my Westell wireless DSL? Does it have to be a Westell or will any 802.11g card do as long as I have the software?
Thanks

i am on lan network but i am not the admin so naturally dont have the reuter when i try to connect it connects good but after few hours the network fail by itself although the green light of the lan card flashes, when i asked my admin he told me that he had to disconnect then reconnects the reuter, then the connection is regained when he does that, wha is the problem?
