Hello,
I'm not sure this is the correct place to ask my question, but I've been
searching on google for ages now and can't seem to find an answer so I'm
asking it here.
If not, please yell at me and tell me where to go whine instead ;-)
I'm using CM11 a/b/g cards with the Atheros AR5414A Chip, which have 2
antenna connectors.
I only have 1 antenna connected to the MAIN connector.
Running a self compiled 2.6.29 kernel on a few debian lenny boxes with ath5k
module for the wireless cards, set up in mesh mode.
Seems to work fine on the test bench, but behaves rather poorly in
production environment.
Everything related to the mesh network setup seems to work, but I have about
40% - 60% packet loss on the entire netwerk (about 15 nodes)
I'm guessing this has something to do with the antenna diversity setting.
Can anybody tell me how to tell the ath5k module to disable antenna
diversity and only use the MAIN antenna ?
If this is a RTFM thingie, then I apologize, I just can't seem to find it
anywhere.
Please reply to my personal e-mail address as well, I'm not subscribed to
the list.
Thanks for your help.
Regards,
Hans
After this patch...
https://lists.ath5k.org/pipermail/ath5k-devel/2009-April/002264.html
It's possible to tell the driver to use one fixed antenna (in your
case its fixed antenna A). Just change...
ath5k_hw_set_antenna_mode(ah, AR5K_ANTMODE_DEFAULT);
with
ath5k_hw_set_antenna_mode(ah, AR5K_ANTMODE_FIXED_A);
Seems like a quite recent patch ;-)
I've been reading up on how to patch the source myself, but I'm not sure
I'll succeed without breaking things.
I can manage pulling the git repository and compiling the ath5k module,
but I'm no expert at patching stuff.
Any pointers where to look for a simple howto on 'the proper way' to
apply these patches ?
Any idea when this patch would make it into the git repository ?
we will have a better way to change this in the future ;-)
That would be nice, I know most users don't need to change this and can
live with default settings, but there are so many possible scenarios
where one would want more specific control over antenna settings.
Thanks for the help!
Hans
