f you suddenly have a problem with your
network connection, before you make any changes, you must determine
whether you have a problem with (1) the wireless device on the computer,
(2) the connection between the computer and the network , or (3) the
connection from the ISP provider to the network. Each of these devices /
connections must be operating independently before they can all work
View the wireless icons in the system tray
to determine the status of the devices and connections. Then, open the
appropriate utilities for detailed information on potential problems.
The detailed windows are: the Windows Wireless Network Connection, the
HP Wireless Assistant, and the Device Manager.
When you have the detailed information, identify the specific type of connection problem
by reading the connection description statements below. Then select the
statement that most closely describes your problem for a detailed
explanation of the corrective actions.Internal
wireless networking adapters or PCMCIA cards may have problems
connecting to a wireless network if the Advanced options are not set
properly. For instance, some PCMCIA devices can adjust the power output
to increase the strength of the wireless signal.NOTE:If
the computer and router are in the same physical area, you may want to
reduce the signal strength to save battery. However, if they are not
located near to each other, you can turn the power up to 100% to
maximize the signal.Most HP
internal wireless cards can be set to turn off to save battery power. If
the wireless connection was working but suddenly stopped when using the
battery, the card may be turning itself off exactly as planned. You can
use the Device Manager to specify the power settings and keep the
wireless card turned on.To verify and change the wireless device settings in the Device Manager, do the following actions.
, Control Panel
, and then Device Manager
Click the plus sign (+)
next to Network Adapters
. If multiple devices are listed, you should check the devices one at a time.
Right-click on the network adapter, and select Properties
.Select the Power Management
tab, if available, and verify the power settings. Not all wireless device drivers have a Power Management option.
you have set the Power Management options, close the Device Manager,
restart the computer, and attempt to reconnect to the wireless network.
Sounds like your hardware WIFI card has failed inside the laptop. The easiest thing to do would be to get an external PCMCIA or USB WIFI card. Many of them are available for under $15.00 on ebay.
I would suggest a PCMCIA WIFI card which will leave your usb ports free.
You can check with ACER to find out what a new wifi card would cost and if they have any manuals to show how to replace it. I have had many laptops pulled apart and it is much more difficult to replace internal cards and parts than on a desktop.
Below is a link to an ebay page with laptop WIFI cards auction listings.
I hope that this information .helpful and will leave positive feedback for me if you do.
