Re: Wifi TEW-649UB RSU(4) problem

[Jake Swensen]

Thank you, Stefan.  How should I implement the below fix in my system?

Should I install the latest OpenBSD snapshot after a few days?

Regards,
Jake Swensen

Yes, it was broken in r1.32 (before 5.9):

So the driver sets IFF_OACTIVE at init and no frames will pass out.

This fixes it:

Wifi TEW-649UB RSU(4) problem

[Jake Swensen]

Hello,

My name is Jake Swensen and I would appreciate any help with using the
rsu wireless network adapter driver.

My friend's RTL8187L 802.11g USB wifi adapter works well (with the urtw
driver) on my laptop with OpenBSD 5.9 and 6.0 but I am not able to get a
Trendnet TEW-649UB to work.  It worked when I had FreeBSD installed on
this laptop, so I don't think the hardware is damaged.

I understand that 802.11n mode is not supported by rsu(4) but I also
tried "sudo ifconfig rsu0 mode 11g" and "sudo ifconfig rsu0 mode 11b" --
neither mode worked.  I am running a fresh install of OpenBSD 6.0
snapshot from 2016-07-24 because I thought it might have a newer driver
than OpenBSD 5.9, which I was previously running on my laptop.

Initially the firmware did not load at bootup because it's not included
with the default install, so I ran fw_update and then it appears to have
loaded at bootup.  However, some error messages are displayed and an
IPaddress cannot be assigned.

user@pc15 ~ % sudo fw_update -v
Path to firmware: http://firmware.openbsd.org/firmware/6.0/
Updating: rsu-firmware-1.2p0


user@pc15 ~myConf % ls /etc/firmware/rsu*
/etc/firmware/rsu-license /etc/firmware/rsu-rtl8712fw


Partial dmesg output for the rsu0:

11n USB Adapter" rev 2.00/2.00 addr 3
