DW1520 Wireless N WLAN half mini card issue driving me crazy - PLEASE HELP!

I have a Dell Studio laptop with a DW1520 Wireless N WLAN half mini card that is intermittently switching off wireless on start-up under Windows 7. If a connection is made at start-up it works fine however every one in three start-ups fails to initiate wireless (I see a red cross over the wireless bars in the system tray). To date I have tried the following however none of these solve the problem.

1. FN + F2. Nothing happens
2. Unchecked "allow the computer to turn off this device to save power" under power management
3. Restarting the WLansvc service

At present my only solution is to repeat restarting the laptop until I regain a wireless network connection. I am also hearing a faint distorted playback of the start-up windows tune on start-up when wireless start-up fails and was wondering whether this is indicative of a hardware fault with my wireless card however this may be a red herring!

Is there any easy way to determine whether this is a hardware fault or software configuration with my network card? The problem is intermittent and does not happen on every startup which is confusing. Any suggestions or ideas would be appreciated as this problem is driving me CRAZY! Thanks - Jabba

Re: DW1520 Wireless N WLAN half mini card issue driving me crazy - PLEASE HELP!

Hi, After a bit more investigation I have found that I can launch the Dell Windows Mobility Centre by pressing [Windows Key + x]. This application has an option to switch the wireless hardware radio on and off rather than simply enabling\disabling wireless using [FN + F2] which does not work if the radio is off.

Whilst this is a workaround rather than a fix I thought I would mention it. I will probably call Dell Support tommorrow however would welcome any other ideas out there as this is still very annoying...

Jabba,

 

The program that you mentioned that uses the Windows key and the X keys is called Dell QuickSet and is usually found on laptops. Some computer4s have it setup that F2 turns on the bluetooth, so that may be the reason for the button change.

Re: DW1520 Wireless N WLAN half mini card issue driving me crazy - PLEASE HELP!

Thanks Rick, Today I called Dell technical support who updated my BIOS to v10 and advised me to monitor the situation for the rest of the day. After three restarts the wireless radio was disabled on the third. As a consequence I have also installed the latest Dell Wireless WLAN 1520 Half MiniCard Driver (Version: 5.30.21.0, A01, Release Date: 10/7/2009) from the Dell Support Site and will monitor for occurrences of the same wireless radio problem for the rest of the day. Assuming this does not fix the problem does anyone have any further suggestions on the next course of action? Any help would be greatfully appreciated.

Regards, Jabba

Jabba,

 

The only thing I suggest is this...

 

 

Go to device manager(right click my computer, left click properties, left click hardware, left click device manager). Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

I have the same problem with the same card on my Dell Studio.  Thanks for the Windows+X tip.  Did the new driver help?  You sure are right about this issue being frustrating.  Turning off the power management properities didn't make a difference.

I have been having a few issues with my DW WLAN 1520 card. I actually also tried a different adapter (USB Dongle) and still could not see my home wifi network.

I could see nearly every neighbours network and yet couldn't see mine with my Dell E6410.

All my other wi-fi devices in my  house worked fine so was a bit frustrated with why I couldn't use my work laptop at home.

So I used this utility: 

<ADMIN NOTE: Broken link has been removed from this post by Dell>

The DW WLAN utility allows you to get very detailed info about your card and driver and once I looked at it I found the solution.

Problem was my laptop was provided by a US company and is a US build with the @ key in the wrong place Smiley Wink (The @ key is not the problem but does annoy meSmiley Happy

I had configured my home wifi network to use channel 13 simply because it had the least noise in my area of London (every one has wifi running on overlapping channels these days.. not good).

Check this article:  on types of wireless networks in different countries.

After looking at the WiFI utility I saw the driver was installed in United States mode.. Not sure how to change this yet, nor do I want to as its not my laptop.. but what the information tab of the utility showed by that channel 13 wasn't in this list.

 So I changed my home wifi network to use channel 11. and straight away it showed up in my available networks Smiley Happy

In the last 10-12 years of tinkering with computers never had to troubleshoot an issue like this.. but you learn something every day!! Smiley Happy

 trevalex,

 

Certain Countries have diferent restrictions. I think that IEEE 802.11 - Wikipedia explains things well.

Yes I had looked at wiki

But think you miss the point of why I posted my process of troubleshooting..was to help others rather than lmwtfy (let me wiki that for you)

Wikipedia is great for geeks etc.. and a self confessed one myself..but I think the content in the dell articles is more relevant.
