Realtek RTL8822CE 802.11ac only sees b g netwoks

My laptop only sees the 2.4Ghz Bs and Gs wireless networks.

I have created a 5Ghz AC network, that is visible on another laptop, just network manager doesn’t see it.

How can I configure my networking card to also see the 5Ghz AC networks?

Here’s my inxi:

So you use the Module from the Kernel.

I’ll just mention personal experience, which might or might not be relevant.

We have an ac router. I could never get the 5GHz channels to work.

Then we had our aluminum siding replaced with vinyl siding (for unrelated reasons). After that, I rechecked and the 5GHz channels now worked.

It’s possible that the problem you are having is due to some other source than the particular computer.

Could be. I just moved and I changed the wireless router config from repeater to simple router.

I’ll have to look further into that.

Thank you
