This can only mean one thing that the wireless adapter is already bad and needs a replacement, you can get a external wireless adapter...

Why not perform a system restore back to when you know the wireless connection was working. That's the first thing I would try. It might not help but, heck, it sure couldn't hurt and it well may solve the problem.

Its has something to do with your built in wireless card. If it's not listed under device manager, your built-in wlan card is already not functioning. Here's what you can do.

1. At the bottom of the laptop right under the wireless switch, you can see there a cover that you can unscrew. That is where the WLAN card is plugged in. If you can unscrew it, you can try to unplug and replug the wireless adapter there.

2. Another option if you can't do the step above, you can simply buy an external wireless notebook card so that you can still connect wirelessly.

3. If you don't wanna buy a separate wireless notebook adapter, claim your warranty because your WLAN card is already defective.

Hi, Does it at least show as some unknown device in Device Manager? if not, card is defective. You have to replace or check its connections.
If so see, Goto HP website and download the specific driver and install.
Good Luck.

I'm going to assume you have turned your laptop off and back on again. Then you looked at the device manager and can't see your card.
Can you see an ethernet peripheral with a question mark by it?

If so, right click on it for properties and select install driver. Navigate to where your driver is and install it. Then power cycle your laptop again and see if it finds it.

If you can't see the question mark in the device manager, then I would physically remove the card again and try to reseat it in the slot and reconnect it. Maybe it's not seated in the slot correctly.

Let us know how that goes.

    Drivers aren't going to help you in this case. The adapter is bad news, and your going to have to get an external solution (external adapter).

    Try downloading and installing updated drivers, if you have XP you will not find the drivers on HP website.

    If nothing works, buy an external LAN card for few dollars here:

Compaq Presario F700 Windows Vista Home Premium My Network Card has stopped detecting wireless connections and tells me there is no network adapter installed. It was working then stopped several days...


If you can use the cable connection
you can search for a new driver for the lan card for vista here:

http://h10025.www1.hp.com/ewfrf/wc/pfinder?lc=en&dlc=en&cc=us&lang=en&tool=&query=F700+#N284

Try using the auto detect function it will tell what model
you have.To get the right driver.

Also try use the microsoft update function
in your start button.

Hope this was helpfull.

Compaq presario f500 wireless not working


Hello, I too had the same problem: wifi card does not exist in the network switch and light orange. I solved it this way: I unscrewed the screws at the memory compartment where it also houses the Wifi card, next is the battery backup of the bios, I pulled gently on the battery connector and I shorted the two pins for 1 minutes, I reconnected the plug closing the compartment and access your PC and Wi-Fi switch has returned the little light blue and WiFi networks are detected. I hope that you too can be solved in this way. Hello Michael

Hi

You could try to go to your network area and check that it has not been disabled somehow

or try a system restore back to when you think it was working ok

good luck

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 lan just quiet working and yes the switch is on


first check in device manager if there are any conflicts if so go online and download the lan drivers to install. if this does not work you will have to buy a ethernet card. usually no drivers needed if running xp or newer. if that does not work a total restore is inevitable.. good luck

Go to HP's website: you must get the exact model number beyond just F700.  look at the sticker.

WLAN Driver


Get new drivers for the lan card from the lan cards web site...its not the XP OS problem...it is a problem with the drivers for the card...the one that XP is assigning to it is not an exact match.
