Wireless not turning on

I have a compaq F700 and when I turn on the wireless switch, the LED does not turn ON. The adapter does not show up on my device manager and I tried re installing the driver but it stil did not work. 
I would like to know if this is a hardware problem or if there is any other way I could fix it.

Posted with no OS stated, windows XP . guess at VISTA.

is your photo top let above it? a mini-pci card, inside
or some other type, is it orginal?, not updated ?
it has words on that sticker, and matter BIG TIME.
what drivers match and must match THAT and your Unstated OS.
for sure.

f700 as in a 2007 latptop.
im reading your service manual took me 2 second to get it.
Atheros AR242 (is one of three used) then.
this PC came new with Vista 32 or 64?
guess what, that needs to match to. and not stated.

ill guess 32bit.
no full service tag shown here, so cant guess what you REALLY have, never can we,,, the p/n on said tag tells which of the 3 chips your PC came with new.
2 Atheros chips or the Broadcom.

there is one magic trick run all 3 drivers the one that dont barff loading is the good one.
if lucky, the HP SP12345,exe loader check to be sure
the one you picked matches your card.
if the card was change, (like a newer intel card ) then all 3 fail.

if all that is confusing
see your F700 series, PC , its NOT ONE PC its all these
and unstated by you,off that service tag sticker

If you can’t see it in the device manager under network adapters or unknown devices, it’s probably a hardware failure

SOURCE: Wireless network adapter - Vista

This may sound stupid, but a possible solution to some of the problems above might be to turn on the wireless properties on on the laptop (may not be the correct terminology). On my laptop the wireless switch does not turn on the wireless, unless the wireless radio button is pre-selected. This is found in a pop up at the top centre of the screen, or possibly by right clicking on the wireless icon and selecting 'enable' or 'radio on'. In my case it certainly was not a driver or hardware issue.

SOURCE: not detecting any wireless networks

Try this.

According to manual. You are to install "Driver" first. Thus, turn your computer off. Remove Wireless card,rReboot, run Dlink supplied "Driver" while your wireless card is still out, complete the installation. Turn your computer off, install hardware, turn back computer on.

If this doesn't solove the problem, try allocating your computer near to router and try above step again.

SOURCE: Wireless Adapter missing from Device Manager


Please check whether your notebook Wireless Adapter is detected in the Notebook. To check this Click start and in the start search box type Device Manager and press enter. This will open Device Manager. Then Click on + sign next to network adapters and please check whether the wireless adapter is listed.( Broadcom or Intel Wireless Lan ) . If it is not listed then you need to install BIOS update for your notebook. After installing BIOS update it should resolve the issue. However, if the issue persists. I am afraid that you need to get your notebook repair.

All the Dv 6000, DV9000 and V6000 notebook has the manufacture defect with the Wireless adapter.


If you find above information is helpful. Please rate me.

SOURCE: XP does not recognize the Intel wireless network adapter

Dell has a known problem with driver conflic the best remedy is to right click on my computer click on property open hardware uninstall the driver there and restart the conputer but first make sure you download the driver from intel and burn them on a cd then when you reinstall you won't have to try to figure out if everything is downloading also in security make sure that you allow this site so that all the drivers download.
but most of the time if these driver are on a card that is micrsoft certified it will be in the driver file and will reload automaticly when you restart the computer after uninstalling and it should elimenate the driver conflic.

My wireless assistant has stopped working and the light stays orange

I had the exact same problem...and the wireless adapter was not visible under device manager. The light stayed orange with the switch in either the on or off position. I did all the whole driver update thing and eventually replaced the wireless adapter but no change. Finally I went into the BIOS (F10 on startup) and reset the bios configuration to the default settings EXIT>LOAD SETUP DEFAULTS). It has worked perfectly ever since.

Wireless led does not tur on it is always off

If the light is off it can be one of three reasons... one... it is failed and is replaceable or it is turned off by your Opperating Software or in your Systems Bios.
If it has worked lately...then it is on in the Bios. If it has never been used...go into the Bios by Selecting "F2 or DEL" key(s) as you boot. It will take you to a Text System Setup Area (Bios) and you can browse around and look for the On-Board Wireless LAN to be ENABLED. If you are not sure what you have done in the Bios, you can always exit with no changes. Save Only if you have located a change that will turn on the LAN.
Option 2 is go to the Control Panel and to Network and see if the Wireless Shows in addition to your Wired Network. If it is missing... you may have a failed peice of hardware. If it is Greyed out... Right Click to see if you can Enable it. If it Enables... Light show appear.
Of course option 3 is... it has failed. If it has you can confirm by going to the Device Manager to See under Network Adapters... if you don't see 2 items.. it has failed.
It can be replaced or you can simply purchase a USB WiFi Card for about $50. Consider the "N" Series for better proformance. "G" minimum.

Hi,i have a hp g6000 laptop with a compaq f700 motherboard fitted.the laptop works fine,but does not recognise the dual core processor or wireless card(not show in device manager with wireless button on or...

The reason it shows the compaq logo is because that is the motherboard you have installed. HP is just your case if I am reading your question properly. Did you custom build this? Which processor is in it? Probably the wireless card isn't being recognized because of your 64 bit operating system. Windows 7 has a lot of hardware driver problems right now.

You'll have to be a bit more specific on this.
Do you mean you have a wireless adapter (most modern computers do) and it doesn't connect or doesn't show up, then I would suggest looking for the switch that turns it on. Many laptops have a little switch on the case that turns the wireless function on. Others use a soft switch, which is a combination of the Fn key and one of the special function keys.

Can you describe what software/program you are using to establish the wireless connection? What colour Led is located near the wireless button? Ornage of Blue? It should switch from orange to blue, if it stays orange, the Wireless card is broken. This is a known issue on all HP DV6xxx, DV9xxx but also on allmost all Compaq V6xxx units.

My Wireless adapter is not shown on my computer .I have A Presario F700 that works perfect except this glich.I have gone to Network and Sharing and it shows my home and work Ethernet connection but NO...

You need to check if your wireless adapter is on by going to device manager and looking for wireless adapter etc,assuming you are using a windows o/s. You also need to check if you have switch on the adapter manually as many laptop provide a button or manual key to put it off for power efficiency reasons..Hope this helps and rate my answer.Thanks

Wireless not functioning

There should be an indicator LED to show that the wireless device is on. If no light, you need to turn it on. If it's red, the device has failed. Quickest/cheapest fix? Buy and install a USB wireless adapter.
