Realtek RTL8822BE cannot connect to 5Ghz wifi band

[KelvinLau]

My new AIO PC, which has a Realtek RTL8822BE wifi card, does not connect to my mesh router Asus Lyra Trio on the 5GHz band. It can only connect to 2.4GHz band.

After some research, and the post below, I realised this wifi card supports only a limited number of channels in the 5GHz band. I tested with a spare router - with default settings the spare router is invisible to the PC. Then I set to channel 36 on the spare router, and it becomes visible to the PC.

I am dissappointed that HP did not point out this limitation in product specs. I would not have bought this PC if I had known. Too late....and my current router (the mesh) does not have the option to set channels, so the PC is reduced to 2.4GHz band only.

Does anyone know if HP has any plan to fix this limitation?

Thank you @Banhien

I know what the specs say, and I did not claim that it doesn't support 5GHz band. I said it supports only limited channels on 5GHz band.

I've already tried the latest driver and chat with HP Support. No solution in sight.
