WiFi interface does not come up.

[AlexTS]

Hello Experts,

Could you please take a look at the folowing:
I have installed CentOs 7.9.2009 on my Lenova Ideopad 3 laptop with Realtek bult in wifi adapter.

When i run

Code: Select all

ip a

it displays the interface wlp2s0 with its state DOWN

When I try nmcli --> activate network I simply see an empty list, ei, there is no wifi adapter to activate shown.

if I run nmcli radio I get the following

Code: Select all

WIFI-HW  WIFI            WAN-HW  WAN
enabled    disabled       enabled     enabled

If i run nmcli radio wifi on - it does not change anything

Since this is only network device I cannot access internet to tun yum/apt.

Could you seggest me please how I can enable wifi

I'd guess that Realtek has made many different adapters.
Can you run these two commands to see if you can find a model number:
lspci
lsusb

Make that lspci -nn as it tells more useful info.
