I am having the same issue with my Pavilion 790 desktop. I have tried all the steps outlined and still frequently get disconnected from Wi-Fi with a Default Gateway is not available error. My wireless adapter is a Realtek RTL8822BE. I paid extra for this particular adapter and am very frustrated that the only solution seems to be to replace the adapter with a different stand alone one.

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you are having issues related to Wireless on your HP Desktop. Don't worry we'll work together to help you find a solution.
To provide you with an accurate solution, I'll need a few more details:
Did you make any software or hardware changes on your PC?
Have you tried connecting your laptop to different networks? Does it work?
Have you checked if you have connected the LAN cable on the router to the LAN port instead of WLAN port.
In the meantime, let's try these steps here:
Manually change network settings
Manually changing the network settings can resolve wireless connection issues. Create a restore point in Windows, and then manually change the network settings.
Using the search box on the taskbar, search for and open Create a restore point.
The System Properties window displays.
Type a name for the restore point, and then click Create.
Windows creates the restore point.
Using the search box on the taskbar, search for Command Prompt. In the results list, right-click Command Prompt, and then click Run as administrator.
If a User Account Control screen displays asking if you want to allow the app to make changes to your computer, click Yes.
Type the following commands one at a time, pressing Enter after each one.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
To open the TCP Global Settings, type netsh int tcp show global in Command Prompt and then press Enter.
Make sure all settings are disabled except Receive-Side Scaling State.
Close Command Prompt, reboot the system and then try to connect to the Internet.
Next thing, I would suggest here is to Run Windows Updates troubleshooter -
Download and install the troubleshooter from this link.
Now try to perform Windows Updates -
1) In the search box, type and open Windows Updates.
2) Check for updates.
3) If the updates are available, click on install and restart the computer.
If the issue persists, I would suggest here is to uninstall the wireless drivers from device manager and install the latest drivers either from our HP support website, using this link or download it using HP Support Assistant.
Note: Before uninstalling the wireless drivers make sure you connect the ethernet cable to your PC and then uninstall the drivers.
Right-Click on start button> click device manager> Network adapters>then select the wireless drivers and right-click on it and uninstall the Wifi drivers.
Then restart the computer and check if you are able to go online.
Finally, please update the bios, chipset and wifi drivers from this link: http://hp.com/drivers Please select the country and follow the on-screen instructions.
Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
Refer this link to know how to use HP support assistant.
Could you please respond to this post with the details and with the results of the troubleshooting as this will help me in further assisting you.
Eagerly waiting for your response!
