Brings the inteface up alright, but i don't see any 5 or 2.4 GHz signal with
a Wifi analyzer nor can i connect.
The 'nwid' and 'wpakey' options should appear on the same line.
You don't need to specify 'wpaprotos wpa2' since this is the default.
Got it. Yes, it's working now, but the bandwidth is the same.
The channel is available, but i am only using one antenna. I remember trying
with both didn't help, though.
If you use 11n mode you must have 2 antennas connected for MIMO.
Otherwise it will perform rather badly since MIMO frames (MCS-8 to MCS-15)
are going to be lost.
Ok, so with a,b or g this ought to be fine fine, then.
Meanwhile is there a mini PCI chipset that will do 54Mb or more in hostap
mode?
54Mbit where? You're not going to see tcpbench displaying "54Mbps" on a
"54Mbit" AP if that's what you're expecting to see.
Typically "54 Mbit" refers to a specific modulation scheme (64-QAM with a
3/4 coding rate) used to transmit the data payload of an 802.11 frame.
But transmitting a frame involves a lot more than just sending payload data,
so user-visible data rates are much lower and depend on many factors.
In my experience tcpbench over 11a maxes out at around 20-30 Mbps on a
clean channel.
I didn't know that, but that's what i meant.
Regarding other chipsets, if you want the fastest possible AP on OpenBSD
your best option right now is to get a bwfm(4) device, which offloads almost
all of its 802.11 operation into a firmware blob running in the embedded
system on the device. So far, this is the only way to have an OpenBSD 11ac
AP (with the caveat that about the only OpenBSD wifi code you're running
is the code that handles WPA handshakes; everything else is offloaded).
Hm, that's almost like buying a wlan router, not really what i want.
