RHEL 8 - NM doesn't see Wi-Fi card

Posted by codemaster63@reddit | linuxadmin | View on Reddit | 1 comments

I need some help getting Wi-Fi working on a Linux machine. It's a pretty simple machine that has two Ethernet interfaces and a single Wi-Fi NIC. Currently we are using the network-scripts ifcfg files for the static IP addressing on the two Ethernet NICs and DHCP for Wi-Fi. All the networking functions work as designed, but network manager cannot see the Wi-Fi interface (wls2). I've been able to get the Wi-Fi card to pull an IP from the DHCP server utilizing wpa-supplicant and DHCP client. The problem I keep encountering is that the route table is not getting updated for the Wi-Fi connection. From what I read online, NetworkManager is in charge of managing routes and here in lies the problem. Nmcli shows the Wi-Fi interface as "unavailable" and nothing I do seems to bring it online for network manager. Both of the Ethernet interfaces are working fine with nmcli. I'm really at a loss on how to resolve the problem.

OS: RHEL 8.10

Thanks for the help!
