OpenBSD Wifi Capability
 
I have a laptop (ASUS F550L) that I have recently installed OpenBSD 6.3 on.
This laptop used to run Windows 8 before and had built-in Wifi capabilities (it could connect to my home's wireless router).

Is OpenBSD also able to do this? During the install it didn't detect any networks (unless I plugged in an Ethernet cable, and that is the only way it gets internet at the moment).

If OpenBSD can't make use of the Wifi hardware in the laptop, is there a wireless adapter that I can buy that OpenBSD can recognize and use?

Thanks.

There are many wireless chipsets supported by OpenBSD. But not all. If you are able to post your dmesg(8) we can at least see what the OS has to say about the hardware it discovered during boot.

Support is based on chipset, rather than brand, which can make predetermination difficult, as chipsets used by vendors are not always published, and are subject to change without the vendors changing make or model.

There are a number of USB-attached wireless chipsets supported. To my understanding, most inexpensive USB dongles on the market today are based on the Atheros or Realtek chipsets noted in this list, extracted from "$ apropos wireless":
Code:
uath(4)        Atheros USB IEEE 802.11a/b/g wireless network device
upgt(4)        Conexant/Intersil PrismGT SoftMAC USB IEEE 802.11b/g wireless network device
ural(4)  Ralink Technology/MediaTek USB IEEE 802.11b/g wireless network device

The above seems relevant, I think.

The touchscreen on the laptop works when I run xfce, so I'm sure there is a way to get the wireless adapter to work. But I am no good with driver/hardware stuff.

However I am happy to just buy any USB Wireless Adapter that will work with OpenBSD.

Thanks for any help.

Your wireless NIC was recognized, but is not supported. The "not configured" message means, "there is no matching driver available."
Code:
"Atheros AR9485" rev 0x01 at pci3 dev 0 function 0 not configured
Edited to add: your re(4) device is your wired NIC, and is unrelated to the wireless NIC.

00x 08-14-2018 08:16 AM
OK, thanks for letting me know that was the problem.

I was expecting it to not work anyway, so while on my search for an adapter, I tried typing `man urtwn' and it had a list of adapters that are supported.

Now I have bought the edimax ew-7811un
https://www.megabuy.com.au/edimax-ew...r-p219664.html

So that should accomplish what I want hopefully.

jggimi 08-14-2018 02:21 PM
Should. There is always a chance that the the chipset was altered without a change to the product model number. As I noted in my first reply, this does happen from time to time among peripheral equipment suppliers. It's relatively rare, though.
