I have lost my wireless connection for my Acer Aspire 9300-5349

Check the wireless router and high-speed modem.

If the two are not powered on, or if the Ethernet cable connected the two is not completely inserted into both connection ports, you are unable to access the Internet on the Acer Aspire One laptop computer.

Activate the wireless Internet connection on the laptop computer.

Right-click the wireless icon on the desktop, then choose "Enable" from the pop-up menu.

Without activating the wireless receiver on the Acer Aspire One, the laptop is unable to detect any wireless network.

Select the appropriate network you wish to connect to.

Your computer may be attempting to connect to a different Internet connection, preventing you from access the network you desire. Right-click the wireless icon, select "Search for available wireless networks," then choose the network you want to access.

Restart the computer.

The system may have booted and failed to detect the wireless receiver. Restarting the computer corrects this issue.

hope this helps

Try this press the colored Fn Key and F2, this toggles WiFi on/off.

When you lost the battery your computr may went to hibernat to protect everything, you may need to reset the connection again, see if you need to keep the hibernat as it is bad if you are not carful

Open control panel scroll down to Internet connections and click to display. Right click wireless wizard then click choose enable. After this you will be prompted with a box that will show you that the computer has detected wifi connection in the surrounding.

I found these 3 drivers on Acer's Website. I have labeled each of them with the Manufacture of the wireless card they are intended for. If you know who the manufacturer of you card is then try that download first, if not try each one until you get the right one (I would try the intel first, then the broadcom, and finally the atheros.)

Atheros:

Relax.. check all your drivers in device manager:

Vista- type device manager at startup
XP- right-click my computer -> hardware -> device manager

Make sure all the drivers is ok with no question marks or errors, if it does, reinstall your drivers from your driver CD.

Hi,

please check your power configuration profile under control panel.
the device might be disabled when the power input is on.

If you are using, Acer's e-manager then you can confirm there as well if the device is disabled under Power on mode.

Hope this helps.

Thanks.

Look on the Function keys on the keyboard (the F1 through F12 keys) Do you see a wireless icon on one of the keys? If you do, then look for a Function (Fn) key on the keyboard. Press and hold Fn, while holding Fn, press the funtion key with the wireless icon (example: the wireless icon is on the F2 key; press and hold the Fn key, while holding the Fn key, press F2, release both keys).

There are a couple different flavors of Aspire One, do have an XP Home machine or is it running Linux?

Are you connecting via the ethernet port or the wireless?

Post additional info so that we may assist.

try to turn on the wireless bottom on your front-panel.

if that not work. go the connections and check if wireless connection is deactivated.
