Recently, I have been having trouble with my wireless internet. The problem is inside my computer as my roommate's computer connects fine and I've tried using my computer at friend's houses and other places with wireless connections and couldn't connect. The problem started about a month ago. Sometimes the computer would connect, sometimes it wouldn't.

Today, at someone's suggestion, I took Norton off. This disabled the firewall on my local internet but my local internet still won't connect with an ethernet cord and i'm still having problems with the wireless.

Also, the wireless card doesn't show up under Device Manager...unless I'm looking for it in the wrong spot. Under Network Adapters is 1394 Net Adapter #2 and NVIDIA nForce Networking Controller.

Is the wireless ccard dying/dead? If not, what's wrong and how can I fix it?

Computer: HP Pavilion dv9000

To what are you trying to connect by ethernet with that static IP configuration? I suspect that using a dynamic connection will clear that problem. If you are connecting to your modem remember to power cycle it when switching devices.

You may be experiencing the HP motherboard problem that causes a "disappearing wireless adapter." Sometimes it is intermittent. Before assuming that though check to see if it got disabled in the BIOS (Setup) or has come loose.

for the static connection I am connextng directly to the router given to me by my service provider (I.e not the wireless router). How do I power cycle and how do. Check to see if it has come loose (it's a laptop) or look in the bios for it?

To "power cycle", you remove the power connection to the modem for 30 seconds.


To configure DHCP, do this.

Select Start > Settings > Network Connections.

• Double-click the Connection icon of the connection you wish to modify to open the Connection Status window.
• Click the Properties button to open the Connection Properties window.
• Click to highlight Internet Protocol (TCP/IP).
• Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
• TCP/IP Properties window, IP Address tab
• Select Obtain an IP address automatically.
• Select Obtain DNS server address automatically.
• Click OK to return to the Local Area Connection Properties window.
• Click OK to return to the Network Connections window.

When you first turn on (or reboot) your laptop check the instructions (probably at the bottom of the screen) for what key to tap to get into the BIOS (or Setup). If Windows begins to load you were too slow and need to try again.

There are two or three removable lids on the bottom. The wireless adapter is probably under the one nearest the wireless switch.

got it...except, lids? Can you explain what you mean?

[TerryNet]

By lid I mean cover or door or hatch cover. A piece of the bottom surface that can be removed by removing (usually two) small screws.

Ok, checked the lids. Everything is secure. In the Bios there isn't a "wireles"s or "broadcom" adapter, but there is a "network adapter" and that has an exclamation point next to it which means it is disabled I think. How do I enable it?

[JohnWill]

Actually that means it has an error or it's drivers aren't loaded. If you open it's properties, it'll give you an error code for exactly what the issue is.

John,

Thank you. When I look at the broadcom adapter in the system information screen - you'll see that I didn't include a driver above - there isn't one. Is there supposed to be? The network adapters were those that came installed in the computer. Why would it have lost it's driver? And, how do I replace it? And, finally, where can I find that error message? I'm having a hard time locating it on my computer and it's not showing up in device manager.

Also, the place where I found the network adapter with the exclamation point was under boot order in the bios.

[JohnWill]

Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.

1. Under Network adapters, please tell me all the devices listed.
2. Are there any devices under Network adapters that have a red x displayed?
3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?

[croftraider]

Under Network adapters the devices listed are:
- 1394 Net Adapter #2
- NVIDIA nForce Networking Controller

None of these have a red X. I am using the local internet ok now after the power cycling suggested.

There are none that have a ? or ! displayed. I tried reinstalling the driver for the wireless card. When I did so (but before I restarted the computer), it appeared under the device manager but didn't show up in network connections. But, when I restarted the computer (to allow the reinstall to take full effect), it disappeared.

[JohnWill]

If the wireless adapter doesn't appear either under Network adapters or under Other Devices, you have a hardware issue. If it's a built-in adapter, it could be disabled in the BIOS. Otherwise, you'll have to see if it's not seated correctly, or is simply bad.

[TerryNet]

Uh, John, actually this is the part of the movie where you came in; you just didn't realize it. Post # 9 is after the adapter's physical connection was checked, and the exclamation point is in the BIOS.
