So, over the holidays I bought myself a HP Envy x360. It’s a beast of a machine but is also fairly light. I got the AMD version with SSD, so it’s exceptionally quick but can be noisy at times (which is quite manageable and easy to fix).
After almost two weeks of using it though, I realised that the WiFi card would not see specific WiFi networks. Specifically, I had issues with 5GHz networks – some would appear, some would not, and the most irritating of it is that my phone and the Bear’s could detect those networks easily but Envy (yes I am calling her that) could not.
As it turns out, this was a software issue that affected the Realtek cards. The good news? HP or rather Realtek has issued a fix, but getting it is a hassle. This is what HP doesn’t tell you in the forums.
Diagnosing the Realtek RTL8822BE
Follow these quick steps to check if you have the same problem as I did.
Your laptop with the Realtek RTL8822BE card (or a Realtek RTL8xxx card in general)
Phone/other 5GHz WiFi enabled device
Access/control over the router
1. Look for a 5GHz network on your HP laptop/device.
2. See if the 5GHz network appears on your phone.
3. If the 5GHz network appears on your phone but not on your HP laptop, log into your router.
4. In your router, set the assigned Wifi Channel for the 5GHz network to any channel between 36-48.
5. Restart HP laptop/device if required and check if you can see the network now on your HP device.
If you can see the network, congratulations, you have the same issue as I did.
Fixing the Realtek RTL8822BE unable to detect 5GHz network issue
Note: Until the driver download website is updated, you will need to contact HP Support to get the updated driver for the network card.
- Plug your machine into the charger.
- Download and update the latest BIOS firmware from the official HP site.
- Once completed, install the driver you got from HP Support – they may send you a FTP link to download it.
- Go through the Diagnosis steps mentioned above to confirm it’s fixed.
And that’s it. The most tedious part of the process is actually talking to Tech Support. They actually Remote Desktop’ed into my machine to check but from what I could see, most of it was unnecessary, if you knew what you were doing. Good luck!
