modprobe -r removes it, you need to run it again without -r to load it again

Code: Select all

[root@ldellg3 ~]# modprobe iwlwifi
[root@ldellg3 ~]# modprobe iwlwifi
Where should I be looking for the results of the loading?

that card should be supported by the latest CentOS kernel.
and, because it's a fresh install, I have no other kernels from which to boot so I could 'yum reinstall' this kernel.

If there are any messages from the modprobe then they will be in /var/log/messages and/or dmesg output.

I just did modprobe iwlwifi with no on-screen result. However, this then showed up in the messages log:

and this when I ran dmesg:

Re: Intel AC-9462 driver/firmware

Post by lightman47 » 2018/09/05 14:41:11

OK - after much research, I am convinced I am waiting for CentOS 8, whenever that comes along. While visiting the Intel site where they state their support for Linux, I notice virtually all their modules now require kernel 4.14 +.

I guess I've almost resigned myself to the fact that my new laptop has to stay home, or can only go places where I can bring a network cable & plug-in. Yes - I've seen posts from folk who've "imported" a kernel ... I'm thinking I don't need the headaches that go with it.

Thanks for the help though; I do appreciate it.

jje

P.S. Ordered a wifi USB stick in the meantime.

Yes but RH backport massive chunks of the 4.x network code to the el7 3.10 kernel. Plus iwlwifi already claims to support that exact device according to modinfo. If you modprobe iwlwifi (if it isn't already) then run ip link sh do you see anything in that list?

I'm suspicious I'm fighting something In the (huge/complicated/GUI) BIOS. There's another (USB) adapter with drivers installed - it doesn't show up either. As a matter of fact, it was also plugged in for the result above.

- or microcode?

Can it be backed-out with a 'yum erase' to see if that's blocking the devices/drivers? A post from mghe* got me wondering ... there's no logical reason why multiple adapters with 'supported' drivers aren't recognised by updated C7. This is just crazy. I'm in grasping-at-straws mode! I spent a good deal of money on this Dell but can only use Internet in rooms that have cable outlets.
