When I try to connect to WiFi on my Ubuntu 22.04.1 system (tried it on Fedora 36 as well), I get displayed the following error: "No WiFi Adaptor found". The most important issue I found is that the kernel drivers and modules don't show up for the network controller.
I tried running the following suggested commands:
lshw -C network
returns:
WARNING: you should run this program as super-user. *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: ioport:2000(size=256) memory:c0900000-c09fffff WARNING: output may be incomplete or inaccurate, you should run this program as super-user.
lsmod | grep rtw
returns nothing
lspci -v | grep Wireless
returns:
pcilib: Error reading /sys/bus/pci/devices/0000:00:08.3/label: Operation not permitted
lspci -v
returns this information about the network controller:
01:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b852 Subsystem: Lenovo Device 4853 Flags: fast devsel, IRQ 255, IOMMU group 12 I/O ports at 2000 [disabled] [size=256] Memory at c0900000 (64-bit, non-prefetchable) [disabled] [size=1M] Capabilities: <access denied>
I have a working Ubuntu setup in my other laptop and I noticed kernel information under the network controller but can't find the same here. Also, the I/O ports at 2000 are disabled here. Not sure what I should be doing from here on out. I tried searching up but couldn't find much information on device b852. I'm fairly new to Linux so please feel free to correct me.
Other information: The laptop I'm using is a Lenovo IdeaPad 5 14 (AMD Ryzen 5 6600)
Thanks in advance and any help would be much appreciated!
EDIT (Adding another command's output):
Lspci -nnk | grep 0280 -A3
returns:

lspci -nnk | grep 0280 -A3
Is there some reason you installed 20.04, an older version of Ubuntu for this quite new laptop? Welcome to Ask Ubuntu. – chili555 Aug 25 '22 at 20:40
