Hi,
I have not been able to compile wireless-testing because of the
stlc45xx error I posted.
While waiting for a response I decided to do some more testing/checking.
I have a laptop with an 11n card in it and running a late kernel. I
checked the kernel and found that all the 11n stuff has been turned on
and the ATH9K module, see below, seems to be ok too.
I forced my router, dlink 655-dir, to go to ch 11
Wireless Radio : Enabled
802.11 Mode : Mixed 802.11n and 802.11g
Channel Width : 40MHz
Channel : 11
Secondary Channel : 9
WISH : Inactive
Wi-Fi Protected Setup : Disabled
However, it was still connecting at 11g.
The iw list below shows that the MCS only goes to 7 when I thought it
should go to 15?
Any thoughts?
Thanks,
Brian

All,
Just to let you know that after downloading
wireless-testing 2.6.32-rc5-wl-1 I have managed to get a clean
compile:))
Currently running off it with no connection problems.
However, I still cannot get an 11n connection.
The details below are still current. i.e. the mcs only goes to 7.
In addition iwlist gives me
iwlist wlan0 rate
wlan0 unkn info.vendor = 'Atheros Communications Inc.'
pci.product = 'AR9285 Wireless Network Adapter (PCI-Express)'own
bit-rate information.
Current Bit Rate=54 Mb/s
while iw list gives me the details below.
Thanks,
Brian

You get up to MCS 7 because of the card you have, if you have
a single stream device that is the highest MCS rate for it.

Luis,
I understood the difference between the two lists.
I also understood from your previous remarks that because I had a
single stream chip mcs7 was all I could get.
Does this prevent me from using 11n though?
I am currently doing a compile on another laptop which I am pretty sure
is multistream, so will test there too.
I also noticed that from the list you get
HT MCS set: ff 00 00 00 00 00 00 00 00 00 00 00
but on the multistream you get
HT MCS set: ff ff 00 00 00 00 00 00 00 00 00 00
What does the second set of ff mean?
Thanks,
Brian

No, MCS 1-7 are for 11n, what you have is an 802.11n single
stream device.

The MCS set is parsed and is where we get the supported MCS indexes.
I am too lazy to check the exact location of the second ff here but
mostl likely it parse out to the other set of MCS indexes. In other
words you can ignore the MCS set print out as it is already parsed
by iw list anyway.

Luis,
Thanks for the explanation/s, understood.
Unfortunately that leaves me with the problem that I do not understand
why I am not connecting at 11n?
I will try to set up some trace to investigate further.
