Network Card and keyboard not detected Ubntu 22.04 dual boot

**brueb44** · September 8th, 2022

Hey all,
Keyboard as well as network card arent detected when when trying out Ubuntu from a USB and also not after installing Ubuntu from said USB.
Ive browsed some stackoverflow pages to see how to diagnose the problem.
The firs thing I did was try:

Code:

sudo lshw -C network
  *-network UNCLAIMED       
       description: Network controller
       product: Realtek Semiconductor Co., Ltd.
       vendor: Realtek Semiconductor Co., Ltd.
       physical id: 0
       bus info: pci@0000:02:00.0
       version: 00
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress cap_list
       configuration: latency=0
       resources: ioport:2000(size=256) memory:81a00000-81afffff
  *-network
       description: Ethernet interface

       bus info: usb@10:1

       serial: a0:ce:c8:fb:3f:95
       size: 1Gbit/s
       capacity: 1Gbit/s
       capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation
       configuration: autonegotiation=on broadcast=yes driver=ax88179_178a driverversion=5.15.0-46-generic duplex=full ip=192.168.178.132 link=yes multicast=yes port=MII speed=1Gbit/s

The UNCLAIMED keyword confuses me. What does that mean? That output doesnt tell me enough about the exact card type so I tried the command below:
It also seems that there is no driver for the network card, as that would show up in condifurtions: driver = xyz

Code:

sudo lspci -nn | grep Net -A2
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852]
03:00.0 SD Host controller [0805]: O2 Micro, Inc. SD/MMC Card Reader Controller [1217:8621] (rev 01)
04:00.0 Non-Volatile memory controller [0108]: Intel Corporation Device [8086:f1aa] (rev 03)

Im not really sure how that helps.

I also have an issue with my built in keyboard, which doesnt work. It does work however, in the GRUB menu. An external keyboard works as well.

Code:

xinput
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ ELAN2841:00 04F3:31AD Mouse                 id=15    [slave  pointer  (2)]

    ↳ Integrated Camera: Integrated I             id=13    [slave  keyboard (3)]
    ↳ Ideapad extra buttons                       id=14    [slave  keyboard (3)]
    ↳ USB USB Keyboard                            id=9    [slave  keyboard (3)]
    ↳ USB USB Keyboard System Control             id=10    [slave  keyboard (3)]
    ↳ USB USB Keyboard Consumer Control           id=17    [slave  keyboard (3)]

Most of this output is gibberish to me, so would much appreciate any help.

Kind Regards

Quick update: after switching over to windows heres some mode details regarding the network card:
Realtek RTL8852BE WiFi 6 802.11ax PCIe Adapter
The keyboard itsself is a standard PS/2 keyboard
The windows driver used is as follows:
Driver C:\WINDOWS\SYSTEM32\DRIVERS\I8042PRT.SYS (10.0.22000.653, 152.00 KB (155,648 bytes), 9/7/2022 5:24 PM)
