Most laptops sold now have great networking features that allow you to connect via Bluetooth or wireless Internet to other devices for ease of transferring files. While these features are great, they can often be turned off without your knowledge, leaving you in dismay as to why your laptop isn't working. The best bet in this case is to troubleshoot and see what is causing the problem for your connection.
Verify that the Bluetooth or wireless Internet is actually off. You can usually select the connection in the bottom right of your desktop. If wireless Internet is off, most of the time an icon will be there with the universal "No" sign on it, the red circle with a slash through it. You can also check the lights on the front of the computer to see that they are all on; if the letter "B" light or the satellite dish light is off, the connection has been turned off.
Locate the Bluetooth and/or wireless switches on the side of the notebook. The Bluetooth icon may or may not be there, depending on what version of Acer Extensa you have, but if it is there it looks like a capital B. The wireless symbol is generally a satellite dish with a signal coming off it.
Turn the switch to the opposite location. This will take a moment or two to show you that something has changed with your connections. Within five seconds you should see activity in the bottom right of your desktop signifying a connection.
Windows Mobility Center (Vista Only)
Click the "Start" button and select "Control Panel." Choose the "Mobility" option.
Click on the option that says "Turn Wireless On." If there is no problem with the wireless connection on your end, this option will say "Turn Wireless Off."
Save and close the pop-up windows to change any options you adjusted.
Tips & Warnings
- It's easy to unknowingly switch the signals off just by the way you pick up or carry your notebook. If you notice a problem, check the switch first.
