Hi there,
I'm a new user of gentoo, and I'm having some problems getting all of my laptop's hardware recognised by the kernel. The most problematic is the one stated in the title: that I managed to find the right drivers and my wifi has been working occasionally, but somtimes disappears. It's not listed in ifconfig -a, lspci or lshw.

I saved a log of dmesg | grep -i pci both when wifi was working and when it isn't, and the only differences I can spot are these:

    When it's working, these entries are shown for pci 0000:03:00.0, but not when it isn't
    Code:
    [    0.122419] pci 0000:03:00.0: [8086:24fd] type 00 class 0x028000
    [    0.122521] pci 0000:03:00.0: reg 0x10: [mem 0xef000000-0xef001fff 64bit]
    [    0.122831] pci 0000:03:00.0: PME# supported from D0 D3hot D3cold
    [    0.187273] pci_bus 0000:03: resource 1 [mem 0xef000000-0xef0fffff]

    And when it's working, these entries are shown for pci 0000:00:1c.5, yet they aren't present when it isn't working
    Code:
    [    0.115733] pci 0000:00:1c.5: [8086:9d15] type 01 class 0x060400
    [    0.115809] pci 0000:00:1c.5: PME# supported from D0 D3hot D3cold
    [    0.126524] pci 0000:00:1c.5: PCI bridge to [bus 03]
    [    0.126531] pci 0000:00:1c.5:   bridge window [mem 0xef000000-0xef0fffff]
    [    0.187229] pci 0000:00:1c.5: PCI bridge to [bus 03]
    [    0.187234] pci 0000:00:1c.5:   bridge window [mem 0xef000000-0xef0fffff]
    [    0.195505] pcieport 0000:00:1c.5: AER enabled with IRQ 122
    [    0.195586] pcieport 0000:00:1c.5: Signaling PME with IRQ 122



Thanks for any help you can give

Usually when it's no longer listed in lspci, you have a hardware problem. If it's flaky, it's usually the latter.

Things to try:

0 - Are other OS happy with the card all of the time?
1 - Try resetting PNP in BIOS.
2 - Reseat the card, if it's removable

I would've thought it was a hardware issue myself, but I had similar problems when I was running Windows 10 not too long ago, and the wireless adapter got replaced then (or so I was told), so I was inclined to think it would be something else. Also, one of the other issues I'm having is that I can't see the touchpad in lspci either, but that definitely works in other OSs, so I thought there might be some other cause for them not showing up.

The wireless card however is not always happy on other OSs, so I'll try resetting PNP and looking inside the laptop.

Thanks
