Wireless not functioning

For some reason, my wireless does not show up in network connections. Even the antenna switch in the front of the laptop, if set in the ON position, does not light up, saying that the wireless in on. I went to the Toshiba support site and DLed all the drivers for WiFi and installed them, but it still does not work. Any ideas?
The hardware is not recognized by my computer I think, b/c even when i turn the toggle switch to the ON position, the Led indicating that it is on does not light up, and there is nothing appearing in network connections window The net adaptor does appear in Device manager, and it is enabled and says it is working properly, I used the driver disc and reinstalled all drivers from the webstite - I have the Atheros wireless LAN one. I also tried to do a system restore to yesterday because it was working this morning and now it is not. What happened in between is that my keyboard went haywire and started typing LLLLLs and wouldn't stop and therefore started opening and closing windows...Since it was just the keyboard (it hasnt worked in a while, nothing new happened) I uninstalled the keyboard driver so it wouldnt function at all. I think that or the keyboard craziness somehow either corrupted or uninstalled my wireless hardware. ..I've checked the Bios and the wireless device does not appear there, also if i run ipconfig only one connection shows up, but in network connection 2 local area networks come up...but still no wireless.
Also it is probably important to mention that there is no problem with the router, because my roomate is using it to pick up wireless and is on the internet right now and bc I am using to connect directly "wired" and it works that way. It is just my computer that cant pick up and in fact seems to have forgotten that it has wireless capability at all.

    "No wireless networks were found"shows up in my satellite pro 6100 laptop. Internet search hinted that wireless may be off and it can be switched on by Fn+F8 keys. But in my laptop if I push Fn key F11 lights up and nothing happens by pushing F8.

Reinstall it clean or reinstall wireless drivers..after that just unplug the router and let it reconfigure ..this will get the wireless network in sight again ..sometimes it just stops transmitting or makes issues like that ..but if the wireless card is fine ..than all it may be wrong is the router ..In worse case just reset the router and configure it again .. but I think it will be enoug to unplug it for 30 seconds..

How to connect wifi


yeerat,
The system has a wireless switch located on the front of the computer. The switch enables or disables the wireless antenna. Since the system does not have Quickset, there is no additional function for this switch. For information on setting up your wireless connection you can click the link below.

HOW DO I TURN ON THE WIRELESS ON MY TOBISHA LAPTOP


If you're using a Toshiba laptop and you can't figure out how to enable WiFi you probably aren't alone. Thankfully there are several approaches you can take from a hardware and Windows Operating System stance to turn on your wireless connection while making sure you can properly connect to a wireless network.

      Look at the keyboard options on your laptop. You should see a button that looks like a small antenna. The button placement may vary from device to device. For instance, you may have a dedicated button or it may be placed much like the option circled in the picture to the left of this step.

      Click on the "Windows Start Button" and Navigate to "Control Panel" then click on "Network Connections" or "Network and Sharing" depending on your version of Windows.

    • 3

      Right-click on your wireless connection icon once the "Network Connections" window opens. Choose "Enable" and left-click on that option with your mouse. Wait for the wireless connection to enable.

      Alternatively you can try clicking on the " Windows Start Button" and then clicking on "Connect to," where you will click on "Show all connections." When the connection window opens up, you should right-click on "Wireless Network Connection" and then choose "Enable." Now right-click on "Wireless network connections" and then choose "View Available Wireless Networks" to see if your WiFi adapter is enabled.


Hope this was helpfull

Wlan is disconnected. How do I get it conected please. Thank you Julie


If it is showing that it is "Disconnected" that simply means you are not connected to a wireless network. To connect to a wireless network simply double click on the wireless icon by the clock (bottom right side, looks like a computer monitor with waves) and select the wireless network you wish to connect to.

Hi - VAIO vgn-fz21m - can't locate the wireless switch/function


HI,
when you try to connect to the wireless network, you must be getting a message " turn on the wireless switch on your laptop "
See there must be a sliding switch on your laptop. it could be on the side panel or on the front panel. Try to locate the wireless switch on the laptop.
it must be having a wireless symbol on it like TOWER or Wireless signals.
On some laptops it is a combination of keys like Fn+F2 or Fn+F5.
If you have the user manual you will find the information about the wireless switch.

I keep losing the internet signal and going offline. LAN indicates pending??? How do I perform a system reset with Linux??


Power cycle the system by shutting it down and switching it on after at least thirty seconds. Check network settings to verify the IP address and other related information. Determine if the network card is working adequately. Identify the malfunctioning adapter by disabling the cards one by one. Move one of the portable hosts--such as a laptop--closer to the router. If it works better, interference or low signal strength is the reason for poor Internet access. Inadequate signal performance can be caused by several factors including cordless devices working within the frequency range (2.4 GHz) of a wireless network, shiny surfaces and too much distance between hosts and access points. Resolve this issue by using a wireless repeater?a device that amplifies wireless signal so it reaches distant areas within the premises. Minimize signal interference by maintaining a distance of at least one meter between cordless devices and the router. Alternatively, buy gadgets that function at frequencies other than 2.4 GHz. Try changing the WiFi channel for better results. Check the functioning of wireless router and access points. Adjust the router antenna to get an optimum signal. Most wireless routers come with omni-directional antennae to send signals in all directions, a situation appropriate for a square-shaped network. If hosts are arranged in a linear fashion, use an antenna that sends signals only in one direction. Some portable routers have internal antenna, giving more freedom to users who are on the go. Use an external antenna with such routers. The market now offers antennae with varying strengths, implying some are more powerful than others. See if using a more powerful antenna fixes the problem. Aside from increasing the range of transmitted signals, the reception capacity of hosts can also be enhanced. External WiFi-enabled antennae attached to laptops are now available for this purpose. Change the location of the router and access point. They should ideally be placed centrally between all computers. As the signal bounces off smooth and shiny surfaces, routers and access points should be placed away from windows, doors, mirrors and other metallic surfaces. Examine signal performance by using the monitoring utility that typically comes with the access point. Check that the devices show correct lights. Device lights are an indicator of accurate connections. Different lighting patterns indicate different things. For example, some network cards show green light on successfully establishing a connection. Similarly, the router's wireless LAN (WLAN) light is turned on at all times, even if no device is connected to it. Further, this light blinks when a host communicates with another host. Unexpected lighting indicates a problem. Go through user manuals to get familiar with this feature and make sure the devices show desired lighting behavior. Use wireless Internet utilities to check the SSIDs and channels neighboring wireless networks are using. Change your network's SSID and/or channel if they are the same as that of other networks in the vicinity. See if correct drivers have been installed. Check configuration settings for encryption keys.

Can't find the wireless antenna on my msi u100 series laptop


Not really sure what you are expecting. The wireless antenna is within the computer--you won't see it.
What you will need to do is to turn the wireless networking on. This is done in some computers with a small switch on the case (in this case, there is usually a light that comes on when you turn the switch on). In other cases, you will have to use the Fn key plus one of the special function keys at the top of the unit (has a picture representing a wireless connection on it--possibly something like an antenna).
If this fails, go into your network connections and see if the wireless connection is actually turned on. If you have Vista, this is sorta easy as you click on "connect to" and then choose "wireless network"

Can not connect wirelessly with router


The list of wireless routers that are available in Windows is very limited and the signal strength of any router that is detected is weak. This can occur when the Lite-On USB Wireless 802.11 b/g hardware and Windows are not able to fully synchronize the signal strength data. Figure 1: Example of detected wireless devices when the antenna cable wire is connected to secondary port c01153759.jpg Figure 2: Example of detected wireless devices in the same environment when the antenna cable wire is connected to primary port c01153760.jpg To correct this error , download and install Lite-On USB Wireless LAN Driver Update (sp35177) (in English) from the HP Web site. This update should only be applied if your PC has the Lit-On USB Wireless LAN adapter and is exhibiting the symptom. As a work-around, you can connect the wire that runs from the wireless antenna port to the primary port on the cord as follows: CAUTION: This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
  1. Open the side panel.
  2. Find the wireless networking board by following the antenna wire connected to the wireless networking antenna port on the back of the computer. Figure 3: Wireless networking hardware c01153761.jpg 1 - Wireless network board 2 - Antenna wire 3 - Wireless networking antenna port
  3. Very carefully, disconnect the small wire from the board by gently pulling the end of the wire away from the board.
  4. Connect the wire to the other available port on the board. Figure 4: Available port c01153762.jpg
  5. Replace the side panel, connect the power cord, turn on the computer, and use the computer again to verify that wireless signal strengths have improved.

Wireless not functioning


HI there,

Check the hardware. Most network problems stem from improper software and hardware settings, but occasionally hardware failures are responsible. If a shared Internet connection seems to be down, try to watch a cable television channel if you have a cable modem or use the phone if you have DSL (Digital Subscriber Line) to see if the entire service is down. If it is, contact your ISP to see if there is a problem in your area. Check all cable connections and consider replacing Ethernet cables if the problem seems to be confined to a particular computer or device.

Thank you & post back how things get done..

Wireless does not show up in Network Connections


I had this same problem sometime ago and I first reversed my last action and I still did not get back my wireles. So out of desperation I backed up my files and made use of the recovery disk that came with my laptop, Although I had to wait through the process of deleting the contents of my computer first, after the operating system was reinstalled, to my suprise my wireless connection was initialised and it started working. All I had to do after that`was to point it to the right wireless network to work with. I hope this solves your problem Sahaja.

Wireless does not show up in Network Connections


Did you try - after switching on the "antenna switch" or WiFi hardware - to "Enable" the WiFi adapter, under (XP) Start - Settings - Network Connections - LAN or High-Speed Internet - Wireless Network Connection? (select, right click and select Enable)?

p.s. Once your WiFi hardware is recognized (by Win XP) there is (should be) always a "Wireless Network Connection" in your Network Connections, enabled or disabled, active or not.
