Wireless help! Dell Inspiron 1545

Hey all!
I have a fairly new Dell Inspirson 1545 and until now it was working fine. My wireless internet is now not working. It finds the network fine but then says that it cannot connect. It also will not troubleshoot. The adapter is on correctly and I know it is not the wireless router because other laptops in the house are using the same wireless. When hooked up wired through an Ethernet cable it works fine...
Anyone know what's up?

Make sure that you have not inadvertantly turned off the wireless switch. You can also disable TCP/IPv6 in your adapter properies.

And if i disable that? what will that do? fix it?

The first thing I would do is go into Device Manager, expand Network Adapters, right click on the Wireless adapter then select Uninstall. If asked, do not allow it to delete the drivers, you just want to delete the entry for the wireless device.

Reboot, Win 7 will rediscover the wireless device and reload the drivers. See if that helps, often does.

Ztruker-
Any other suggestions? That didnt work....

I would try a System Restore to before this problem started happening.

How to Do a System Restore in Windows 7

I've tried that...

Click on Start then Run and paste the following into the Run box, exactly as show, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close.

You have no connection to your wireless adapter at all. Please post a screen capture of your Device Manager window: A Preferred Method of Uploading/Posting Screen Shots

Also, please double/triple check to make sure the switch to enable your wireless is on.

Here's the screen capture for the Device Manager. Sorry that took a little while.

All looks fine there. The next thing to try is to reset WinSock and TCP/IP Protocol stack. Open an Elevated Command Prompt and enter the following:

netsh winsock reset catalog (reset winsock entries)
netsh int ip reset reset.log hit (reset TCP/IP stack)

How to open an Elevated Command Prompt:

1. Click on Windows 7 Start Button
2. Go to All Programs then Accessories
3. Right click on Command Prompt and select “Run as Administrator” from context menu.

Reboot and see if that helps. If you want, you can try each one individually to see which one works (if it works).

Hey. I tried resetting both but it didnt work.....

Did you recheck to make sure the wireless switch is on? It sure sounds like it's off.

Nope its definitely on.

Can you do a hard wire to your router or Modem? Using a Cat5 cable.

If we do that then we will know that your internet is working good. We can also narrow down some problems doing so.

Once you connect to your router/Modem with the cat5 cable.. can you repost the IPCONFIG /all

Hay Acurasd.
I've been reading ure answers bout this problem and I'm also have the same thing with me. I have done all the things you have suggested before and still stunt to get my wireless to work. So I have tried it with a cable in2 the hub and took screen shots of the ipconfig\all hoping you can see what this problem is cause it is driving me mad and getting pissed of as I don't no y it's stop working. Hope you can help me and thank you for taking time to read this.

Hi please check if this works.
1.Refresh the drivers.(Device manager) got to device manager>wireless card>Right click>unistall dont check the small box.
2.Power cycle the Router. 3.Log into safe mode with networking(shut down the computer> turn it back before the dell logo starts up keep tapping the F8 key constantly untill you see Advanced boot options choose safe mode with networking)

3.still no go ......... Disable fire wall........check if any other systems are connected to the same network..... if yes...do a system Restore.

4. last option is PC restore.

Can't activate Wireless Adapter: Dell Wireless 1397 WLAN mini-card

Dear All

Thanks for useful advice on this thread but I have tried everything in this thread, to no avail.

I have downloaded the following drivers for the wireless card (R256972 and R242432 from Dell) that are supposed to be the specs for my laptop and settings, but refuses to install as "appropriate hardware not detected"

I have

Windows 7 Professional x64
Dell Inspiron 1545

Dell Wireless 1397 WLAN mini-card
Broadcom File Version 4.176.75.18

Any tips please?
