Can someone explain to me why these registers have been set to such values?
Is this a mistake or it is something done for some reason in particular?
Hi Franco,
What values are you expecting, and why?
cheers,
m
What I was expecting was to have CWmax closer to 1024.
What I think happens when you set CWmax to 31 is that -as you have more and
more machines trying to compete for the medium- you could be having more
colisions -since they would wait less time slots to tx and collisions would
be more likely to

Sure,
I'm looking directly at the registers in the XO 1.5 B2 laptop.
The process I follow is the following one:
# mount -t debugfs null /mnt
# cd /mnt/lbs_wireless/eth0/
To read register 0x
# echo 0x rdmac ; cat rdmac
MAC[0x0] = 0x0033fa05
I've read the following registers:
0xA0A0

Now, this are the four queues I've read, and they have the values:
CWmax = 31
CWmin = 7
The eight registers that follow this ones have the exact same pattern
(7 31 7 31).
That's why I mentioned eight queues (but I might be

Martin,
No idea if that happens, I've only read such parameters since they were used
also by the XO1.0 and

Hi,
Looking for the reasons for low throughput on the XO 1.5 I've come across
with the contention window's registers.
I've found that there are like eight queues and that for all of them the
CWmax and min are set as follows:
CWmin = 7 slots
CWmax = 31 slots
As I see it this would make for a
