Realtek RTL8188EE 802.11 bgn Wi-Fi Adapter is experiencing driver or hardware-related problems

[AsmitaS]

Product number: K8U04PA#ACJ

I was using Virtual Box, which updated and then the Guardian Antivirus detected a virus and asked re-start. After re-starting I was facing "no connections available" problem with red cross over network icon. 

I've reinstalled drivers from HP official site /HP Recovery manager/ downloading and installing drivers through pen-drive from other PC/resetting PC. Nothing works!

All the Network adapters in device manager are showing the same error. So it's not possible to connect to internet any other way. Please help.

@AsmitaS Since the issue began after the antivirus program detected a virus and the device was restarted, did you try disabling it and then check if it connects to the network? Because there's a slight possibility that the antivirus is blocking or deleting the driver, this often happens when there are more than one anti-virus programs on the device, its recommended that you delete one of the two, if that's the current scenario.

That out of the way, If the issue persists after you've done the above, or that wasn't the scenario (as I have a vivid and descriptive imagination), try the below steps:

I request you to check in the device manager if the wifi card drivers are present:

• Open the device manager.

Figure : Example of the Device Manager

• Expand "Network adapters" and let me know what is listed in network adapters.

If the drivers in network adapters do not have a yellow exclamation mark or a question mark then please perform the following steps that can help to fix the wifi issue:

First, we have a step by step guide to walk you through the troubleshooting process here: 
Troubleshooting Your Wireless Network and Internet Connection

A second option, is to try these steps:
Powercycle the network:
1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in the modem, and wait for it to come back online.
6. Plug in the router, and wait for it to come back online.
7. Turn on your notebook, and test your connection.

Disable the Power Off option for the adapter:
1. Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
2. Expand the Network adapters.
3. Right click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the check mark beside Allow the computer to turn off this device to save power.
6. Click OK.
7. Test.

Reset the TCP/IP settings on your PC:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.

It may also help to reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.

Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network.

If those three steps do not resolve the issue, try this document published by Microsoft for networking issues: Wired and wireless network problems.
You can change the operating system with the drop-down in the upper-right corner of the document.
