Hello,

I have OpenBSD installed on my laptop (6.4 GENERIC.MP#1 amd64). I love
it.
And I hope to fix Wi-Fi problem described below. Because staying on wire
is not comfort way :)

My network device is Realtek RTL8723BE Wireless LAN 802.11 PCI-E NIC.

# dmesg | grep Realtek | grep pci2
"Realtek 8191SE" rev 0x00 at pci2 dev 0 function 0 not configured

# pcidump -v 2:0:0

By the way, rtwn driver has the firmware for my device:
# ls /etc/firmware | grep rtwn-rtl8723
rtwn-rtl8723befw_36
rtwn-rtl8723fw
rtwn-rtl8723fw_B

As one can see, the device is detected. Vendor's ID 10ec is Realtek, and
17aa is Lenovo. It's OK, as I see.
But card is not determined properly. However, "Product ID: b723" is
close to reality.
What should I do to match correctly all these entities and to fix
problem with this pci device?
As I see, there are few options to solve my problem.
Could you tell me the best option?

Current state of firmware packages:
$ fw_update -i
Installed: intel-firmware-20180807p0v0 uvideo-firmware-1.2p2
Installed, extra: rtwn-firmware-20180103 rsu-firmware-1.2p1

Thank you.
Stas
