Here it is and no mention of the wifi.

Ah. Thank you. Now we need to know if you actually need it. Run lspci,
and look over the output for likely keywords: wifi, wireless, 802.11,
etc. On the laptop I am using right now, I get, among other things:
charles@jhegaala:~$ lspci
…
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE
802.11b/g/n WiFi Adapter (rev 01)
…

We need more information on that entry. So in this case,
lspci -vv -s 03:00.0
where the 03:00.0 is taken from the line in the first lspci output. The
last two lines give us the kernel driver in use, in this case
rtl8192ce. So now we look to see what the boot output has to say. As
root:
root@jhegaala:~# dmesg | grep -i rtl8192ce

So now we know that the driver is successfully loading the proper
firmware. You may have a line like that, or you may have a line
indicating that it tried to load firmware but failed. If it failed, you
now at least know the name of the firmware file it wants.
This is a Realtek device, your output should look similar.
