Question about Toshiba (PA3212U) Wireless Adapter

2 Answers

Wireless connection is gone

I lent my computer to my in-laws and when I got it back, I cannot access my wireless connection. I checked Network Connections and the wireless connection icon is no longer displayed. My in-laws said they did not uninstall or delete any program/software but they did say they added RAM and had someone install it. How can I get back my wireless connection capability?

    First check to see that both the RAM and the wireless card are properly inserted. I would remove them and re-insert them in the slots. Next, on boot-up, go into BIOS and ensure that the RAM is read correctly and if your BIOS detects it, check that the wireless card is visible. Once booted into the O/S, go into the drivers and see if it registers. If it registers, then go into the wireless network and see if ANY wireless networks are visible. Check and report back please. Good luck

First off verify that your wireless card is there there.

Next verify that the drivers are installed. Go for the latest version.

Enter the proper SSID for the wireless connection and it should pick it up providing that the router is broadcasting and that you have entered in the correct wep password if required.

Slow connection low signal


If a wireless network has low signal strength, the transfer of information across the network could be slow or you might not be able to access certain parts of the network. Here are solutions to some common problems with low wireless signal strength: Your computer is too far from the wireless router or access point. Move your computer closer to the router or access point. If your computer is portable, try moving it around to determine the range of the wireless signal and the best place to use the computer. If you can't get closer to the router or access point, consider buying and installing an external antenna for your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which provides better reception than the built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna. The wireless router or access point is turned off or isn't working properly. There are two things to try: o Make sure the router or access point is turned on and that the wireless signal light is illuminated. o Reset the router or access point by turning it off, waiting at least 10 seconds, and then turning it back on. If you don't own the access point or don't manage the network, contact the network administrator. There is interference from other devices. If you have 802.11b or 802.11g network hardware, it uses the 2.4 gigahertz (GHz) frequency. Other devices that use this frequency include microwave ovens and cordless phones. If you have 802.11a network hardware, it uses the 5 GHz frequency. Some cordless phones also use this frequency. These devices can cause interference between your computer and the network. There are two things you can try in this situation: o If any devices like these are near your computer, turn them off temporarily or move them farther away. o Change the router or access point settings to use a different wireless channel, or set the channel to be selected automatically if it's set to a fixed channel number. Sometimes one wireless channel is clearer than others. In the United States and Canada, you can use channels 1, 6, and 11. Check the information that came with your access point or router for instructions about setting the wireless signal channel. The network you're looking for is set to not broadcast its network name (SSID). Wireless routers and access points can be set up so that they don't broadcast the network name. In this case, you can't detect that the network is in range (in order to connect to it) unless you've previously connected to the network or you manually connect to the network using the service set identifier (SSID). To connect to a network that's not broadcasting, follow these steps: 1. Open Connect to a Network by clicking the network icon ( or ) in the notification area. 2. Click Unnamed Network, and then type the network information. The network will be added to your list of networks and will be available to connect to in the future when your computer is in range of the network.

No enternet access


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

If your computer has a wireless network adapter, Windows will automatically detect wireless networks in range of your computer. You can see a list of wireless networks that Windows has detected in Connect to a Network.

  • Open Connect to a Network by clicking the network icon (eff2d36c-9e0d-4d1a-9859-3af14fa4ccfc_73.jpg or da12251d-1e9a-4032-afae-009876c6c5a3_80.jpg) in the notification area.

If Windows doesn't detect a network that you think is in range of your computer, it could be because of one of the following reasons:

  • The wireless switch on your computer is turned off.

    Many laptops have a wireless switch on the front or side of the computer. If your computer has a switch, make sure it's turned on. Some computers also use a function key combination to turn the switch on or off. Check the information that came with your computer for details on locating the wireless switch.

  • Your computer is too far from the wireless router or access point.

    Move your computer closer to the router or access point. If the computer is portable, try moving it around to determine the range of the wireless signal and the best place to use the computer.

    If you can't get closer to the router or access point, consider buying and installing an external antenna for your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which provides better reception than a built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna.

  • The wireless router or access point is turned off or isn't working properly.

    There are two things to try:

    • Make sure the router or access point is turned on and that the wireless signal light is illuminated.

    • Reset the router or access point by unplugging it, waiting at least 10 seconds, and then plugging it back in.
