Intel-based Macs: Resetting the System Management Controller (SMC)
In some situations, you may need to reset your computer's System Management Controller (SMC). Learn how to identify these conditions and to reset the SMC.
Note: It is possible that the SMC could encounter an issue that may cause unusual system behavior typically related to the symptoms described below. In some cases, resetting the SMC may be the only correct method to resolve the issue. However, an SMC reset should only be attempted after all other standard troubleshooting has been performed.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple menu from the upper-left menu bar and then choosing Shut Down.
If your Mac appears to be running normally but isn't responding, force the computer to shut down by pressing and holding the power button for 10 seconds. Note: You will lose any unsaved work in any open applications.For Mac portables experiencing issues related to the MagSafe power adapter and/or battery, try:
Unplug the MagSafe power adapter from the Mac and the wall power socket for several seconds.
Shutdown the Mac. Physically remove and re-insert the battery (if it's removable) and startup the Mac.
If the issue is still not resolved after following the troubleshooting items above, an SMC reset may be necessary.

I can't turn the Wifi on, Satellite L40-18Z

Hi there,
I've been using Satellite L40-18Z but I can't turn on Wifi.
I'm very sure that Tthe device is installed propery and I tried some ways to turn on Wifi device but never turned on. Of course, never catched the signal. Rooter has no problem either.
Deveice manager says ithe device works propery. And the driver is correctly installed. But I can't turn on from windows mobility centre or network setting.
It's very embarrassing to post something like this but I need your help.
P.S. this is the first time I post on this thread but who answers? Toshiba support team?
Thanks,

I have the same problem. Does anyone cope with it? Have my wifi disabled can't switch it on, tried to reinstall it nothing work.
Have it installed and work correctly thru device manager. Wifi can't be enabled and find network, all other devices are working properly. Access point have no limitation or something else in their settings.
Windows diagnostic can't resolve this issue. Shows that "wifi is still disabled on this computer" FN+F8 doens't wotk too.
Any help are more then wellcome.
I suppose this is Realtek RTL8187B Wireless 802.11g 54Mbps USB 2.0 Network Adapter bug within Thoshiba Laptop.
Thanks in advance.
PS
Running Vista Home Premium that goes with laptop. 100 mb network is working ok.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

The Holy Mecha of Wifi
Turn router off then on Try turning your wireless router off then back on.
Change or turn off wireless security You may want to try toggling the settings on your wireless router, switching from WPA to WEP or vice versa, or, as a last resort, turning wireless security off altogether. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Reset network settings on iPad. On your iPad, open Settings, then navigate to “General” in the left-hand pane. Scroll down and tap Reset, then select “Reset Network Settings.” This will delete any stored WiFi passwords and other information, but may result in a more stable connection.
Adjust brightness upward. Oddly, a number of users have found that they can resolve this issue by simply adjusting the iPad’s brightness level upward and off the lowest setting. To do this, tap Settings, then select “Brightness & Wallpaper” from the left-hand pane. Slide the brightness bar upward, then wait 1-2 minutes and check for an improvement in signal strength. Speculation holds that a power delivery issue associated with the screen brightness affects Wi-Fi.
Change thresholds in router settings. Access your routers configuration screen (for most routers, open a browser and enter the address 192.168.1.1), then change the fragmentation threshold and the CTS/RTS threshold as described here. Some users have found success with the settings Fragmentation= 2048, RTS = 512.
Change 802.11 spec on router. Try changing your router’s wireless spec mode from B, G and N to G only or vice versa. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Switch routers. Although a far-from-ideal solution, some users have found success with switching to a different wireless router.
Turn off “Ask to Join Networks.” To do so, tap Settings on your iPad, then select “Wi-Fi” from the left-hand pane. Slide “Ask to Join Networks” to off. Speculation holds that leaving this option on causes the iPad to constantly seek networks, resulting in some type of interference with the network to which it is connected.
Forget network then rejoin. Tap Settings on your iPad, then select Wi-Fi from the left-hand pane. Choose the network with which you are experiencing difficulty, then select “Forget this network.” Go back to the previous screen and rejoin the network.
Turn off Bluetooth. Some users report that, perhaps due to interference issues, turning off Bluetooth can boost Wi-Fi signal strength. To do so, tap Settings then tap General in the left-hand pane. Tap Bluetooth in the right-hand pane, then slide to off.

Have you tried pressing the round button and the on/off switch at the top at the same time and holding them till an Apple icon appears? If that doesn';t work, take it back, you are still under warranty.

Java is no longer included in Mac OS X by default. If you want Java, you will have to install it.
However, note that you should think twice before installing Java for such a trivial need as looking at stock market quotes. There are other ways to get that information that don't involve Java, and using Java in your web browser is a HUGE security risk right now. Java has been vulnerable to attack almost constantly for the last year, and has become a very popular, frequently used method for getting malware installed via "drive-by downloads." You really, truly don't want to be using it. See:
Java is vulnerable… Again?!
