Solved: Missing Network Adapter
Hello. Set-up new Dell Studio 1555, running Windows7, to the wireless router (Cisco-Linksys WRT160N) that I purchased together and set-up was successful and had a wireless connection. I then installed Comodo Firewall and lost wireless connection and seem to have lost my network adapter in the process. Have since uninstalled Comodo. I've also un/reinstalled Linksys.
After running network diagnostics I received this message, “Reinsert your wireless network adapter. Windows can’t connect to Linksys because the wireless network adapter has been removed. Reinsert the network adapter and then try running again.” I then did a System Restore and still same problem. I have no idea where to go from here and how to reinsert my network adapter.
Please help! Thanks very much, Cindy

Look in Device manager and see if this adapter is listed. It may have been disabled or need the driver reinstalled.

I went into the device manager and it had the network adapter (Broadcom NetLink (TM) Gigabit) listed and it said that it was "working properly". That's strange. Why am I getting that error? Thanks

You should have two adapters listed-One wired, which is probably the one you see, and one wireless, which apparently isn't showing.
Boot to Safe Mode with networking and see if this adapter is listed.
If this device has a switch, make sure it's turned on.Most laptops have a light with a wireless symbol to indicate the adapter is on/off. Do you see such a light, or he symbol?

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?


Let's see this as well.

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Hi.

In DevMgr there are two Network Adapters listed and it says they are working properly: (1) Broadcom Netlink (TM) Gigabit Ethernet, (2) Intel (R) WiFi Link 5100 AGN.

I also didn't see any red X's or yellow "!" or "?">

Here's the info you requested from CMD prompt:

Download and run this Xirrus Wi-Fi Inspector, paste a screen shot of the Network screen here.


To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.

Sorry for all the questions. I did the Xirrus download and it doesn't seem to be reading anything on my computer. There are "N/A" next to everything. There are two buttons, "Connect/Disconnect" and "Enable/Disable". Will either of those buttons activate the program? Thanks

Your wireless adapter is likely to be turned off.
Look for a switch that turns it on.,

I believe that the new Dell Studio 1555 only has the F2 key to turn on the wireless. Can't find a "real" switch anywhere. When I press the F2 it doesn't connect and the troubleshoot says that my adapter is not connected.

Are you holding the function key when you press F2?

When I had the wireless working when I first set it up all I had to do was push the F2, without Fn. When I try the F2 by itself now the radio tower icon appears on screen in lower right as it did when it was working, however it says the the network adapter is not connected. Also, when I just did the Fn + F2 and nothing happened, the router troublshooter said that the WLAN wasn't connected. Hope that makes sense.
