Acer Aspire 5733 Wireless connection lost


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

How to connect to always automatically connect to your SSID


Ever turn on your computer and try to connect to the internet? Ever see all the many SSIDs in your neighborhood listed in your wireless radar or your "Windows Wireless Connection". Then you'd scroll down to double click on your SSID so that you can connect to the internet. Imagine doing this everytime you have to connect to the internet. Wouldn't that be annoying?

The Objective
The objective of this Tip/How-To is to have you turn on your computer and connect to the internet automatically via your SSID (Wireless Network Name). Hence, you wouldn't need to manually find your SSID everytime you need to connect to the internet.

6a6f420.jpg


Pre-requisites or Must haves for this Tip to work
  1. A computer with a wireless adapter
  2. A wireless router
  3. An active internet service
  4. This tip is designed for Windows XP. I will post one up for Windows Vista and Windows 7.
  5. This tip is designed to work with Wireless Networks (SSID) that do not have any passwords or encryption.

Active Tip Dictionary (throughout this TIP)
SSID
is the technical term for your broadcasted network name. This is basically what you will see listed in your WIRELESS NETWORK CONNECTIONS manager.


To make your computer connect automatically to the internet via your SSID, we will need to manually tell your computer to connect to your SSID and then we will need to save this setting so that your computer will automatically connect to your SSID everytime you turn on your computer.

Let's Begin.
Start your computer by turning it on.

Click on your Start Button.
14c207b.jpg

Move your mouse over to Control Panel and then left click on it.
ff339b2.jpg

Double click on the Network Connections icon.
8a673e8.jpg

Double click on Wireless Connection. Now in the picture above you see Wireless Connection 3 but on your screen you should see Wireless Connection.

moz-screenshot-1.png97e1e56.jpg

Now click on Properties.
5381832.jpg

Click on the Wireless Networks Tab.
b119bfe.jpg

Now scroll up and down under Preferred networks until you find your Wireless Network Name (SSID). For me, it's called linksys therefore I will select linksys.

Now click on Properties.
4c1fadb.jpg

Now click on the Connection tab.
52daf8c.jpg

Under Automatic connection, click to check "Connect when this network is in range". This will tell your computer to connect automatically to your Wireless Network Name (SSID).

Click OK to save this setting.

Click OK again to get out of the Properties window.

Click OK again to get out of the Wireless Connections window.

Then click Close to close out of the Wireless Connections window.

And there you have it, you have setup to automatically connect to your Wireless Network (SSID) everytime you turn on your computer.

Now restart your computer and give it a few seconds, and voila, you are automatically connecting to your Wireless Network (SSID). Now you can surf the internet. You can set this on all your computers at home that have a wireless card.

Remember to give me a good rating and vote for me. If you require further tips and tricks, feel free to contact me through the contact box. I will post up your tip.

Please follow this steps carefully

Turn on your internal wireless card?
If your wireless card is built in to your computer, there may be a switch on computer that turns the card off and on. When new from the store, these switches are often in the "off" position. They can also accidentally get switched off during use. Find the switch (often near a symbol that looks like a microphone or radio tower emitting radio signals), and turn it on. The card should now find wireless networks in the area and connect.
.

Find the scrldcolville network?
If your wireless device is properly installed, your computer should automatically start scanning for networks in the area and will inform you that there are wireless networks present. If not, you can scan for networks in the area manually.
*To bring up the Wireless Network Connections menu, go to the Start Menu (in the lower left-hand corner of your screen, choose "Settings," then chose "Network Connections," and finally, choose "Wireless Network Connection." Clicking on this option in the menu should bring up a window. In the upper left hand corner of the window under the heading of "Network Tasks" there should be an option that says "Refresh Network List." Click on this option to search for wireless connections. Choose scrldcolville, hit the "Connect" button in the lower right hand corner and enter the passkey to connect.

Enter the passkey correctly?
If the passkey is entered incorrectly, the computer will appear to connect to the internet, but will not actually connect. If you think you may have entered the passkey incorrectly, disconnect from the scrldcolville network (see steps above in #5) and then reconnect. Often, as you manually reconnect to the network, the computer will remember the passkey and a small window will pop up, showing the password as a line of dots. Re-enter the passkey correctly before connecting.
(#6, cont.): Sometimes, your computer will not allow you the option of re-entering the passkey when you reconnect to the network. If this happens, bring up the Wireless Network Connections menu. Click on the "Change advanced settings" option under the "Related Tasks" heading. Another window saying "Wireless Network Connection Properties" should pop up. Click on the "Wireless Networks" tab at the top of the window. Under the "Preferred Networks" heading, there is a box that lists all wireless connections your computer has ever used. Click on the scrldcolville network to select it. Now hit the "Remove" button just below the box, then hit the "Ok" button. This will make your computer forget the scrldcolville network and the bad passkey. Bring up the Wireless Network Connections menu again and connect to scrldcolville .Be sure to enter the passkey correctly.

Allow your computer to obtain an IP address automatically?
Be sure that your computer is set to obtain IP addresses automatically and that it does not have one assigned manually. To do this, bring up the Wireless Networks Connections menu .Click on the "Properties" button. Here, you will see a list under the heading "This connection uses the following items." Scroll down the list until you see an item named "Internet Protocol (TCP/IP)." Select this item and hit the "Properties" button just below the list. This will bring up a new window. In order to connect with the library's wireless device, you must have the option "Obtain an IP Address Automatically" selected (ditto for the DNS server address). If you are set with a manual IP address, you can click the button to obtain your IP address automatically (ditto for the DNS server address.) Be aware that this changes how your computer interacts with other networks. If you need a static IP address on other networks, you may have to reset your IP address again later. However, your computer cannot connect to the library's wireless network unless it obtains its IP address automatically from the library's wireless device.
Make the Windows wireless configuration your default configuration?
In many computers, Windows acts as the default wireless network configuration program. However, if you have an external wireless card, or if your computer has a secondary program enabling it to connect to the wireless network, you may discover Windows will not recognize your wireless connection program and visa versa. Sometimes, if you have a non-Windows program that runs your wireless card (for example, a Linksys driver for an external Linksys wireless card), the non-Windows program will connect to the wireless device, but Windows will not recognize that this secondary program has connected. You will need to allow Windows to control the wireless configuration in order for your computer to fully recognize the wireless connection. On way to solve this problem is to tell the secondary program to "stand down," as it were.
On some computers, an icon for your secondary wireless program will appear in the lower right-hand corner of the taskbar on your desktop. You can click on this icon to open the program options. Certain programs will give you the option to switch to Windows as the default manager of your wireless connection. This will allow you to use the Windows Wireless Network Connections menu to make changes to your wireless connection.
