Comment(by werner):
I had a quick look in my books about those preambles. Here's what
I found:
- the preamble can be long or short. New equipment, particularly .11g,
supports short preambles.
- the AP should signal if short preambles are okay
- if a station tries to use short preambles but the AP doesn't support
them, you get that error 19
Now, this raises a few questions:
1) why does the AP not support short preambles ? They're good for
performance, so one shouldn't suppress them needlessly.
2) does it signal that they're not supported and the Atheros stack or
firmware ignores that ? Or does the AP fail to signal this ?
3) Can we make the AR6k not try to use them ?
The answer to 2) may be in the logs. Haven't looked at them yet.
The answer to 1) is Mickey's problem :-)
Perhaps I can help with 3):
svn co
http://svn.openmoko.org/trunk/src/target/AR6kSDK.build_sw.18/host/tools/wmiconfig
cd wmiconfig
make CC=arm-angstrom-linux-gnueabi-gcc
scp wmiconfig neo:
ssh neo ./wmiconfig -i eth0 --setlongpreamble 1
Does this help ? By the way, thanks to Marek ! Your hunch about wmiconfig
may have been right.
