I cannot connect to the internet and the only hint that my computer gave is about the wireless adapter. How can I resolve this? By the way, my OS is windows 7. Thank you!

Several computer models include two specific hardware components that enable the device to connect to the Internet: an Ethernet adapter card and a wireless adapter card.

These cards are also called network adapters, or network cards.
If your computer suffers from an intermittent Internet connection, and your Internet service provider (ISP) doesn't detect any issues on their end, you can update the software for the network adapters to resolve the intermittent connection.

If updating the adapters doesn't resolve the problem, reset the transmission control protocol/internet protocol (TCP/IP) and Winsock to restore the connection.

Click "Start." Click "Control Panel."
Type "manager" into the search bar.
Click "Device Manager."

Expand "Network Adapters."
You should have one wired adapter and one wireless adapter, if the computer has wireless support.

Double-click each adapter.
Write down the name of the adapter, as well as the manufacturer's name.

Go to the computer or network adapter manufacturer's website if you installed the adapter to the computer yourself.
If the adapter came with the computer, go to the computer manufacturer's site instead.

Select the "Support," "Download" or "Drivers" page.
Look up your computer or adapter model.

Select your operating system.
Click the "Network," "LAN" or "Internet" category.

Download the latest adapters for your network devices.
Click "Save" or "Save As" and save the files to your desktop.

Return to Device Manager. Right-click the first device. Click "Update Driver Software."
Click "Browse My Computer for Driver Software."

Follow the remaining on-screen directions to reinstall the device driver.
Repeat the process for the other network device.

Restart the computer after reinstalling the drivers to repair the intermittent Internet issue.

Reset IP

Log in to Windows as an administrator.
Hold down the Ctrl, Shift and Esc keys to open Windows Task Manager.

Click "File." Click "New Task." Type "cmd" and press Enter to open Command Prompt.

Type "netsh int IP reset c:\resetlog.txt" into the Command Prompt.
Press Enter to rewrite the TCP/IP registry keys.

Enter "netsh winsock reset" into the command-line prompt.
Press Enter to reset the Winsock catalog and resolve the intermittent Internet problem.

As you mentioned, your Compaq Presario MV520 is using Windows 98 OS. As we all know, dial-up connection is the only available internet connection at that time so obviously Win 98 has dial-up LAN connection. However, you wanted to have wireless connection on that PC so you need to install a wireless adapter to that PC. First of all, most wireless adapters that are being used for desktop PC are wireless USB adapter, so you need to have a USB port on that PC. And also, you will need to check if the software for the wireless adapter will be accepted by the PC because since the PC is using Win 98 OS, we are not sure if the firmware of the wireless adapter will be compatible to the PC. Basically, my answer would be not possible.

OMG a 16 year old desktop gee, why own this?
came with windows 2000, then 2001 XP. both Dead OS. bad news that. why post at all lacking what OS your run of the many./
your ATT guy probably never seen anything this old
for sure 1st tier helpers.... "a look by him and OMG what is that thing)

what adapter, of the many?
wifi, 3/5G wireless, or Ethernet wired.
it came new with zero wireless anything.
wired only and slow. 100GB only.
we cant guess network unless a tiny hint added like wifi or?
looks like it came new with a relic NIC eithernet port slow.
there, and modern OS do not run now on that chip
im reading your relic service manual now for you.

the RJ45 on the rear , is Ethernet (wired)
you connect a CAT5/6 cable to that and to your router.
and it just works, that is if the Intel driver is loaded.
Integrated Intel PRO/100+ Management Adapter

you can delete all the old wireless profiles that you have and then try to click on start > Connect to ....

could have told you in detail but you have not mentioned which OS you are using

Well you have netgear wireless router.On the back side you have 4 ethernet port where you can plug a cable which is coming from telephone.Its up to you if you want a wireless and your computer don't have a wireless adapter then to get a wireless connection you required a wireless adapter.Ya you can use internet connection with erthernet cable also


Hope this will resolve your issue

Hello,

If wireless adapter on the laptop is fairly old, you may need to update the drivers for the wireless adapter. Some older wireless adapters are not capable of properly communicating with WPA devices. Typically a driver update of the laptop resolves the issue. If not, try another wifi adapter and verify it is not the OS or laptop itself.

Good Luck.

check if ur able to gonline with the cable connection. checked if the wireless key entered is correct
try to update the software
go to start-computer-right click-properties-devicemanager-network adapter- rightclick on the broadcom -update driver from the net with the cable connection and this will probably resolve the issue
