Missing WiFi device during install

oldmold · 2022-10-15 22:03:04

For clarity: I am not having trouble finding the networks, I’m unable to find the internal wireless device

I recently purchased a Lenovo Ideapad 5 15ABA7 and planned to install arch on it (it has never booted into windows and I’d like to keep it that way, not planning on dualboot)

I’ve run into a problem that I haven’t in previous arch installs: (I’ll shorthand root@archiso ~ # to just # in most cases)

after running loadkeys dvorak, and checked the efivars, which were both successful,
I ran:

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

then

root@archiso ~ # iwctl
NetworkConfigurat lonEnabled: disabled
StateDirectory: /var/lib/iwd
Version: 1.30
[iwd]# device list

device list output

I then ran

# rfkill

saw that all devices were soft blocked, and unblocked them
output after unblocking

Running iwd device list again produces the same result as before

Running

# lspci
# lsusb

gives the following
lspci output)
lsusb output

Running

# iw list

Came back with nothing

# journalctl -u iwd

gave this: journal

Finally, I ran

lspci -k

which gives this output

which seems to imply that I'm missing the kernel driver (I think?)
but then how did rfkill unlock?

I’m pretty lost at this point, so any help would be greatly appreciated.

Possibly related: https://bbs.archlinux.org/viewtopic.php?id=279621.

EDIT: You probably need to work through https://wiki.archlinux.org/title/Networ … n/Wireless to see if you need firmware or such.

I can add that detail as well, will also copy to main post, since I forgot to on my original writing

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

not sure how to get that (or any) new driver over to the pc in question, since it doesn't have an ethernet port

Figure out first if your card is supported and, if so, by what. You need to gather the relevant information about the card and then check the model against the lists linked in the wiki. E.g. the Ubuntu link would lead you to https://help.ubuntu.com/community/Hardw … ealTek#PCI. The other links to lists will take you to similar collections of information.

If necessary, you can probably download whatever you need and transfer it using a USB key or whatever, but you don't even know yet if there is anything to transfer.

looks like https://github.com/lwfinger/rtw8852be is the correct driver.

I don't think it's in base, so I'm currently looking into making a local mirror for the pacs I need on usb and doing it that way.

You might want to consider using https://aur.archlinux.org/packages/rtw8852be-dkms-git so you produce a package.
Edit:
As there is no network connectivity on the system, have you considered tethering or build the kernel module on a different system (ensure the kernel version matches) then copy the module into /lib/modules/$(uname -r)/kernel/drivers/net/wireless/ afterwards run depmod then modprobe rtw8852be
