Realtek RTL8821CE Adapter isn't working properly

[MBartell]

To say I'm a little frustrated is a MASSIVE understatement, I've been having issues with my network adapter, the Realtek RTL8821CE. My PC was connecting fine the internet, no issues at all (granted a bit slow because of our provider) but I didn't have any issues. Recently, however I've had major issues with the following : 

- disconnects randomly and will not reconnect to home wifi

- connects to wifi but acts like the wifi is not working, "Connected, no internet", when there is internet and other devices connect fine

- Will disconnect and need to be reconnected constantly, while it will drop out VERY quickly and require manually connection - no guarantee it will work if connected 

- Note: It seemed to work and connect fine with my school wifi! Just my home wifi is acting up 

I have tried EVERYTHING I can, the wifi works with other devices in the home, our chromecast TV's, phones, tablet, and it DID work with my computer but suddenly did this stuff. I've ran diagnosing, which narrowed it down to this adapter, I've manually reset said adapter, uninstalled and reinstalled the adapter, ran diagnosing time and time again. I've rolled it back, updated windows, reset my computer, and also made sure it didn't have access to turning off for the battery.  I've tried all the recommended ways of fixing it but nothing so far. 

If I get ANY suggestions on how to solve this issue, that'd be lovely, I'm a college student and NEED my computer to do my online assignments for my online course and design class to submit assignments. I don't understand how it can go from acting fine to this with nothing managing to fix it! 

Thanks in advance!

Hi,

That model wifi adapter is plagued with issues like you reported, and Realtek is constantly releasing driver updates to try and correct the problems with their 8822 and 8821 AC wifi adapters.

The only suggestion I can offer, would be to update the wifi driver to the latest version they have released to HP, and restart the PC.

Ironically, an hour or so after you replied, and me frustrated trying anything to fix it. I reset my computer (the one that reinstalls windows), and somehow, by some miracle it worked and fixed the issue. We'll see in 24 hours if the fix holds up, or I might have to do the same thing again. It's unfortunate the adapter is commonly buggy! Not very friendly for us students with online courses who can't get into town very often to alternate wifi options.
