Question about Microsoft Windows XP Professional for PC

1 Answer

Wireless Connection Good but PC Often Can't Access Internet Sites

All of a sudden my PC can't access internet sites even though the wireless connection is strong. I've attempted all the typical "repairs" including: resetting Explorer settings ; repairing the wireless connection ; disabling/enabling the network connection. The PC is pretty clean with essentially Windows XP Pro and iTunes on it. My other PCs in the house access the internet via wireless with no issues.

My computer seems to disconnect the internet


Wireless or Hard Wired internet connection ?

When you set up a dial-up Internet service connection on your Windows computer, it comes automatically configured to disconnect itself after a predetermined period of inactivity.


This means that if you walk away from your computer and forget that you're online, your internet connection will automatically shut itself down.


If this feature isn't as helpful as you assumed it would be, you can turn it off using the Network and Sharing Center.

Click "Start."


Click "Control Panel."

Click "Network and Sharing Center."


Click "Change Adapter Settings."


Right-click on your dial-up Internet service icon.

Click "Properties."


Clear the check box next to the "Auto Disconnect" listing on screen.

Click "Apply."


The auto disconnect on your computer Internet service connection is now turned off.


also if its running slow


Slow computers that persistently disconnect from Internet access may have issues with the wireless setup or if on a wired connection, there may be a problem with the Ethernet cable or port.

Troubleshooting connection and speed issues can save money rather than taking the computer to a technician or repair shop.


Additionally, some firewalls and security features can make it difficult to access certain types of websites.


Before spending money to have the computer diagnosed, try running through the most common, basic causes of connection issues.


Consider the type of site you are trying to access.

High-traffic sites such as gaming sites can sometimes be affected by high volumes of users accessing or attempting to access the site at once.


Test this by attempting to access the site at different times during the day and evening; peak hours for games that typically appeal to children may be during the afternoons on weekdays while games for older or more mature audiences will see high traffic at night.


Check your Internet connectivity and determine whether you are using a wired or wireless connection.

In the lower right side of the computer screen there should be an icon displaying the Internet or network connection.


Wireless connections are displayed with connection bars similar to those seen on cell phones while wired connections may show the end of a plug next to a monitor icon.


Reset the router if using a wireless connection.


For most home routers you simply unplug the power cord from the router box, wait a moment and plug it back in.


You may have to restart your computer to reestablish a secure connection.


Access the router through the computer and check for updates. Some routers offer firmware updates that fix some connectivity issues.


While updating the router, check for Internet browser updates as well as any critical updates for your computer's operating system.

Verify the computer uses the most up-to-date version of the Web browser available.


Try a different browser. Internet Explorer is the most commonly used Web browser, but not always the best for every site.


Try downloading another Web browser such as Firefox, Opera, or Google Chrome and test the sites there.


If the connections are still disconnected and the Internet speed seems slow, it may be an Internet issue.


Wired Connections


Trace the Ethernet cable from the Internet modem to the computer if using a wired connection.


Unplug the end of the Ethernet cable and check that the plastic head is secure and that there is a click when you return the plug to the modem; do the same on the computer end.


Inspect the Ethernet cable carefully as it runs from the modem to the computer.

If the cable was tacked down with a staple gun or other attachment, check the cable to verify it wasn't accidentally pierced.


Additionally, check for bends, twists or worn areas along the cable.

Measure the length of the Ethernet cable.


In general, cables longer than 100 feet tend to receive poorer signal transmission.


If the cable is longer than 100 feet, replacing with a higher quality cable or moving the computer or Internet modem may resolve connection issues.



Hope this helps.

Hi i have realtek RTL 8187 wireless adapter, and when i watch in my antenna managing program, connection is quality and signal streght about 80% THATS GOOD. always was good connection, but now yellow and...


somebody is accessing your wireless network and getting free internet service from you unless you had setup a wep security! if you have an un-secure network then anybody with a wireless adapter can access your network and access your internet free and drag down the speed of your internet connection.
however, if you do have wep enabled and there is more than one computer connecting then this will slow your connection down as well. please remember that there are some games and gaming sites that are bandwidth hogs and will slow down other computers connection on the same network. also watching streaming videos and gaming at same time can slow down connections as well.

Where is the wireless switch on the dell vostro 200


Unlike notebook computers, most desktops don't come with wireless networking built in. I can't find any mention on Dell's site that the Vostro 200 has wireless capability, so this computer doesn't have a wireless switch. To use your desktop computer on a wireless network, you'll need to install a wireless adapter. USB adapters are very easy to use since you just have to plug them in. They're not expensive and you can easily find them at retail stores and online.

Pls i was trying to fix my engenius radio, and i mistakenly imputes wrong ip from 192.168.1.1 to 172.16.7.1 after rebooting, i cant even access the log on page from internet xplorer again wit boths...


The wireless adapter in your ENGENIUS has connected to a wireless-router.
Depending on which router that has responded, the IP-address assigned by the router could be:
* 192.168.0.xxx
* 192.168.1.yyy
* 192.168.2.zzz
* 172.16.aaa.bbb

If the router to which the ENGENIUS has "associated" has _NO_ Internet connection, then you won't be able to access any web-sites.

You need to "dis-associate" from that router, and "associate" to a different router (one that DOES have an Internet connection).

Internet won't access sites even though it's connected


Go here and upgrade your Router's Firmware -

http://www.belkin.com/support/article/?lid=en&aid=5027

There are one or two actions you could try:

1. Disable Windows Firewall

2. In Internet Options Control Panel go to the connection tab and then the LAN Settings where you can uncheck the "Automatically detect settings" button.

3. If you have any third party software, I would get rid of this and ensure that the"Windows Zero Configuration" in the Services menu is set to "Automatic" and the status is started.

Interestingly, Anti Virus programs sometimes interfere with wireless set up - you could see if it helps by disabling it whilst configuring your wireless. It might also be worth trying to connect without any encryption code & see if that will connect - you can then sort out the encryption.

Wireless adapter gives limited websites


hi debbie
the fact that your computer has internet access shows that your adapter and router is working well

the reason you may be denied access to certain websites may be because of feature called trusted sites in internt explorer

if you hav downloaded mozilla it would import setting from IE so trusted sites would remain

to disable this in ie go to tools>> internet options >>> connections >>> put it on accept all cookies and disable trusted sites

no you are probably unaware that you have connected to a neighbours connection who stupidly has not security encrypted the router.

It is illegal to use somebody elses connection without their permission, so i would suggest turning off the wireless adapter (slider button at front of notebook) until you get your own wireless connection.

Computer cannot access the internet


Try to disable wireless card on your desktop. With both the wireless and cat-5 socket enabled, "WITHOUT" the proper bridge settings, they will conflict and not be able to read.
