Wifi driver problems

[sydherz]

Hey yall,

Installing Gentoo for the first time on an HP N150 with an rtl8852be-vt wifi chip. There are no wireless devices being picked up in the live CD environment.

While poking around a bit I ran these:

Code: Select all

gentoo@livecd ~ $ lspci -knn | grep Network -A3
01:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8852BE-VT PCIe 802.11ax Wireless Network Controller [10ec:b520]
        DeviceName: Realtek PCIe GBE Family Controller
        Subsystem: Hewlett-Packard Company Device [103c:88e9]
        Kernel modules: rtw89_8852bte, wl
gentoo@livecd ~ $ lsmod | grep -e wl -e rtw89_8852bte
wl                   6447104  0
rtw89_8852bte          12288  0
rtw89_8852bt          118784  1 rtw89_8852bte
rtw89_pci              90112  1 rtw89_8852bte
cfg80211             1150976  4 wl,rtw89_core,mac80211,rtw89_8852b_common

I tried sudo modprobe rtw89_8852bte and ran lspci again, but it still didn't list an active kernel driver.

dmesg was mostly clean except for this part with quite a few errors: https://dpaste.com/BZCL45M23

Including this last message, which seems particularly concerning:

"You are using the broadcom-wl driver, which is not maintained and is incompatible with Linux kernel security mitigations. It is heavily recommended to replace the hardware and remove the driver. Proceed at your own risk!"

This is all further complicated by the fact that this laptop doesn't have an ethernet port nor is it recognizing my phone hotspot when plugged in so any fix involving data not already on the live CD would have to brought over on a usb. Any help is appreciated!

Looks a bit like this: https://bbs.archlinux.org/viewtopic.php?id=304887



IOW, your driver tries to load the firmware file, but thinks it is invalid. You could try emerging an older or newer version of linux-firmware, or try getting older versions of rtw89/rtw8852bt_fw.bin in their gitlab repository (https://gitlab.com/kernel-firmware/linux-firmware/).

sydherz,

Welcome to Gentoo.

Code: Select all

[   20.083299] You are using the broadcom-wl driver

is not a problem.
broadcom-wl is for very old broadcom chip sets but you have a Realtek chip.
broadcom-wl is loaded but not used.

Code: Select all

Is your problem.
Try a new copy of the firmware. That says the file you have is not self consistent.
A different firmware velsion may work too.
