Description Forrest Zhang 2013-12-30 03:44:21 UTC

If one of AP/CPE is ath5k, and another is ath9K, they can connect.
In 5MHz/10MHz channel bandwidth, the throughput is abnormal.

ath5k vs. ath5k: 6.5Mbps
ath9k vs. ath9k: 13.6Mbps
ath5k vs. ath9k: <1Mbps

Adrian, fbitterli posted that you were able to have decent numbers between the legacy and 11n chips after addressing "coarse RF channel spacing" in the older chips. Any suggestions ?
