Question about ASUS Z83V Notebook

Wireless network disappeared...!

So, my wireless / bluetooth console is still there, and when I flick the switch on the side of the computer to 'on', the little window comes up saying wireless 'on'. Same goes for the F2 key, or by selecting the console throught the task bar etc. Basically, the computer tells me that the wireless console is on and applied, and good to go. The only thing is, there's no wireless network in Network Connections. Nothing. No option to search for availble wireless networks, no subtitle in the window for WAN or WLAN. It's like the whole wireless internet thing has been erased from the computer. I can get online no problem with a hardline (obviously, otherwise I wouldn't be writing this...), but the wireless thing just seems to have got bored and gone away. Do I need to actually re-install something - what? Or is it an internal thing that I can reconnect or rediscover? It's befuddling, to say the least. Has anybody had this problem, or does anyone have any ideas? I'd really love a speedy solution on this one, as I'm going travelling pretty soon, and having to be tied to hardlines only is going to be a real pain in the ass... Same thing's happened on my friend's laptop (not an ASUS), and all we get are confused looks from people when we ask. Someone - help...!

Re: wireless network disappeared...!

If this has happened since new, as it did to two of my clients, the problem stemed from the fact that the wireless adapter was not enabled in the bios, the notebooks had to be returned, as their technical team could not get the bios to see the adapter. When you boot up your laptop press F2 or DEl depending on the instruction at boot up to enter the bios setup screen. You will need to look in all the menus normally the advanced menu under and peripherals, look to see if the wireless adapter is not greyed out, if so you will need a bios upgrade from asus, but if it's not greyed out select enable, save settings and exit for a restart. Also you may need to go to my computer, right click>properties>hardware tab>device manager and look down the list for any yellow exclamation marks saying unknown device, if this is the case you will need the driver for your wireless adapter. If you see a line saying network adapter, click the '+' sign and see if your adapter is listed, but has a red cross on it if so right click and select install.

Turn on notebook, go to boot menu (F2), go to advanced settings, go to Onboard Devices Configuration, make sure that the WLAN is enabled. Voila fixed!

Re: wireless network disappeared...!

Ok I think ive solved this, I had the same problem ages ago and then again just. when you boot up press F12 to select boot up device and select HDD (sounds obvious but...) you should get the screen you get if your laptop crashes or something where it says start windows normally or start windows repair (or safely... i wasn't really reading it) it will check for errors for a couple of min then restart itself.

When it restarted i could see the wireless device and the little orange light was back on (yay) but still not working when i disconnected the hardline. If you right click and diagnose and repair it will say turn on wireless ability click that and poof it was working again :)

I'm on a Toshiba Satalite something or another and I know its not HP or Compaq but after looking around it seems there are plenty of people getting this problem and end up sending their laptops off for repair, so hope this helps :)

Re: wireless network disappeared...!

I had the same problem on my new asus and eventually i got it running again. make sure you still have the driver disk that came with your laptop and see if installing some things works. i actually got it working another way after that but i have forgotten the process (it happens when you press Fn + F2 before your OS has started and the computer thinks it doesn't exist) dont worry, just take it to an electronics shop and ask for some help they will get it up again.

Bluetooth peripheral device driver

Sai Ch Krishna,

Depending on the system. The bluetooth would have to have been purchased at point of sale. The wireless and the bluetooth are turned on by a wireless switch on the side of the computer. If needed you can reinstall the drivers. Also, make sure bluetooth is turned on in the bios. Below is more information.
Wireless Switch

Wireless Technology The Latitude D630, D631, and D630c system ships with a wireless feature called the wireless switch. It is located on the left side of the system next to the IEEE 1394 connector. When used in combination with the Dell 38482; Quickset utilities, this switch enables or disables the wireless LAN, wireless WAN, and Bluetooth cards in the system or searches for all wireless networks in range.
To scan for a Wi-Fi wireless LAN, slide and hold the switch in the momentary position for a few seconds. The Wi-Fi Catcher network locator works whether the computer is turned on or off, in Hibernate mode, or in Standby mode, as long as the switch is configured through QuickSet or the BIOS to control Wi-Fi network connections.
Because the Wi-Fi Catcher network locator is disabled and not configured for use when the computer is shipped, it must be enabled and configured through the Dell QuickSet utilities to control Wi-Fi network connections.

Wireless Switch LED Settings
The LED on the wireless switch works even if the system is off. A user can activate the switch and have it scan for networks without going through a complete boot process. The switch can be set to detect for only certain wireless signals, such as WLAN only, WWAN only, Bluetooth only, or any combination of these. This is set in the BIOS under the Wireless section.
The LED indicates the presence of a network as follows:
  • Flashing green - The system is searching for a signal.
  • Green - The system has detected a wireless signal and has good strength.
  • Yellow - The system has detected a wireless signal, but it is moderate to weak in strength.
  • Red - The system failed to detect a wireless signal, or the wireless signal is extremely weak.
Thank You,

The wireless network won't connect

Yes, the switch is at the back.

The LifeBook S is equipped with a Wi-Fi (802.11b) receiver; the antennas are inside a long, black plastic panel that runs along the top edge of the lid. The wireless receiver's on/off switch is on the back of the notebook, where the power switch was located in earlier models. Meanwhile, the power switch has moved to a more convenient location on the side of the unit, next to the FireWire port.

Wireless LAN/ Bluetooth ON/OFF Switch
The switch allows you to turn on and off the Wireless LAN/ Bluetooth communications. Slide the switch to the right to turn it on, or slide the switch to the left to turn it off.
