Hi,

I just installed Rocky Linux 9 on a battered Lenovo Thinkpad laptop. Everything seems to run nicely, except the wireless card. Up until yesterday, the laptop ran OpenSUSE Tumbleweed (which hadn’t been updated for at least a year or two as far as I can tell), but the wireless card worked perfectly on this distribution.

Here’s the card:

```auto
# lspci | grep -i net
00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06)
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

```

The driver seems to load OK:

```auto
# lsmod | grep iwl
iwlwifi 417792 0
cfg80211 1290240 1 iwlwifi

```

But the expected interface is nowhere to be found:

```auto
# ifconfig -a
enp0s25: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet 192.168.2.171 netmask 255.255.255.0 broadcast 192.168.2.255

        inet6 ::1 prefixlen 128 scopeid 0x10<host>

        RX packets 10 bytes 1660 (1.6 KiB)

        TX packets 10 bytes 1660 (1.6 KiB)
        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

```

(Yeah I know, `ifconfig`… old habits die hard.)

I gave the `kernel-ml` from ELRepo a spin, but to no avail. Same result.

So before haphazardly reinstalling OpenSUSE Tumbleweed from scratch just to figure out how things are handled under this distribution, I thought I might as well ask here.

Any suggestions?

Some old Lenovo’s had a radio kill switch / slider could it be that? RH has been pretty good about maintaining old intel firmware. I have a t400 with the kill switch.

It’s not a kill switch problem. I investigated this a bit more, and it looks like this is firmware-related. Here’s the relevant snipped from `dmesg`:

```auto

```

Now what ?

I’ll answer this myself, since I just found the solution here:
