No Wi-Fi connection Ubuntu 22.04.2 LTS / PCi Realtek

I have brand new HP computer with windows installed and I dual boot Ubuntu 22.04.2 LTS. Unfortunately there is no internet and I went through many instructions without results. What I have:

1. nmcli command:

    enp1s0: connected to Wired connection 1
            "Realtek RTL8111/8168/8411"
            ethernet (r8169), 7C:57:58:5F:52:E5, hw, mtu 1500
            ip4 default
            inet4 192.168.1.13/24
            route4 192.168.1.0/24 metric 100
            route4 169.254.0.0/16 metric 1000
            route4 default via 192.168.1.1 metric 100
            inet6 fe80::f32e:43c8:a863:6ff1/64

            "lo"
            loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536
    
    DNS configuration:
            servers: 91.227.2.157 8.8.8.8 192.168.1.1
            interface: enp1s0
    
    Use "nmcli device show" to get complete information about known devices and
    "nmcli connection show" to get an overview on active connection profiles.
    
    Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details.

2. lshw -C network command:

I would be very grateful for step by step explanation, cause I cannot use Ubuntu for like a week.

If nmcli doesn't see the interface it might be a driver issue. You might get lucky and find there is a driver ready to install under Software & Updates > Additional Drivers.

Another thing to look at, actually under windows, is to go and un-tick any and all power saving options related to the wifi or bluetooth. The windows driver may be toggling off the device when it shuts down and then ubuntu doesn't have a way to turn it back on. I've seen HP laptops do that.

It looks like lshw doesn't see it either, that realtek device looks like your ethernet.

Another problem is sometimes you might have a conflicting kernel module that prevents the correct driver from loading. You need to know what device it is to approach solving that issue.

You might get an ID on the device with the lspci or the lsusb command.
