On 2 servers, where atheros is installed, there are problem with unexpected
changing "slottime" IFS parametr.
If I set this parametr manually or by new way with using of athctrl.sh for
our correct destination between them, it changes to slottime=12 for example,
but after undefined period it changes back to slottime=9 which is default.
Anothers 2 parametrs ack and cts timeouts is okay.
habr# ./athctrl.sh -i ath0 -d 681
Setup IFS parameters on interface ath0 for 681 meter p-2-p link
dev.ath.0.slottime: 9 -> 12
dev.ath.0.acktimeout: 27 -> 27
dev.ath.0.ctstimeout: 27 -> 27
habr# ifconfig ath0 media OFDM/24Mbps mode 11a mediaopt adhoc
habr# ./athctrl.sh -i ath0 -d 681
Setup IFS parameters on interface ath0 for 681 meter p-2-p link
dev.ath.0.slottime: 9 -> 12
dev.ath.0.acktimeout: 27 -> 27
dev.ath.0.ctstimeout: 27 -> 27
And another question, could somebody recommend me some ath_rate from 3
available options and why ?
I remind that there are available these:
ath_rate_onoe - which is default for fbsd driver
ath_rate_amrr - http://www.marlow.dk/tech/madwifi/lacage04.pdf
ath_rate_sample - which is default for madwifi (linux driver)
After reading the pdf file, ath_rate_amrr is seems to be the best one.
Any comments ?
Thank you for your attention.
