Hello,

I'm using a lot of MiniPCI ral cards in my work with OpenBSD, such as:

dmesg | g ral
ral0 at pci0 dev 16 function 0 "Ralink RT2561S" rev 0x00: irq 10, address 00:1a:4d:28:e0:47
ral0: MAC/BBP RT2561C, RF RT2527

In this case I have Subj question: what is the top speed, that I can get from such stuff?
I'd tested different options and flags from man 4 ral, spent a lot of time on it, tested all the
media from the ifconfig -m ral0 list with all the mediaopt opts. The max speed that I'd saw being
in my office with the total distance between points about 2-3 metres is 11,8 Mbit/sec.

Is it normal? Any dmesg? What about the max speeds that you'd ever seen on ral?  
Can I see smth. about 54 Mbps between 2 OpenBSD boxes? If it is yes, please, what stuff? Producer, vendor?

; Can anybody tell me more about chan option: values, influences, etc? Or, where I can read about it? 

Thank you very much for your reply.

I'd say it's a bit low.  I've seem my maximum sustained throughput at
~22Mb/s, but it usually operates at ~19Mb/s--and I imagine this might
be a bit higher if I didn't use WEP.  I use ral for hostap purposes
and the relevant portion of my current hardware is:

ral0 at cardbus1 dev 0 function 0: irq 10, address 00:14:a5:33:31:c7


I can't say much outside of making certain the channel you're using is
not being used by someone else.

You will not; that is the data rate transmitted by the radio,
which is quoted before protocol overheads are taken into account.

802.11g has about 50% radio overhead, slower speeds have less.
