I switched to Linux today from Windows 11 and completely erased Windows from my PC, but when I started my system, I noticed there was no Wi-Fi option in Ubuntu. I searched YouTube for fixes — nothing worked. Then I asked ChatGPT and spent hours trying every possible solution, but in the end, it still didn’t work. Even ChatGPT eventually recommended using a separate Wi-Fi adapter.

Output of sudo lshw -class network:

I used the following commands to check the Wireless and Ethernet interfaces.

$> lspci -nnk | grep Wireless*
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter [10ec:8179] (rev 01)
        >>>Subsystem: Hewlett-Packard Company RTL8188EE Wireless Network Adapter [103c:804b]


$> lspci -nnk | grep Ethernet
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)
Subsystem: Hewlett-Packard Company RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [103c:2b5b]

I see both of the interfaces.

They also showed up on lshw -C network command.

IMPORTANT NOTE: Please use lspcie -nnk command instead of lspci -nnk because your ethernet device is on the PCIe bus. It is likely that your WiFi device is also on the PCIe bus.

WARNING: you should run this program as a super-user.

In my case, I have the WiFi device reported but DISABLED because I disabled it by ip link set <link-interface> down]

Your image above shows only the Ethernet device because it says port=twisted pair. Also it says *-network UNCLAIMED

Would you try lspcie -nnk | grep Wireless* to check if the WiFi device exists but is disabled?

If that doesn't say anything, then please check if both network devices are working properly, with the command lsmod or lsmod | grep pcie or lsmod | grep rtl8188ee NOTE: I have PCI bus, not PCIe bus; old machine ;)

In my case, they show up as

rtl8188ee             176128  0
rtl_pci                40960  1 rtl8188ee
rtlwifi               139264  2 rtl_pci,rtl8188ee
mac80211             1744896  3 rtl_pci,rtl8188ee,rtlwifi

Please also note that it is recommended to run the commands in super-user mode: as "sudo' to see all the results.
