Hello list, I am following up with Chun-Yeow's report. I used compat-wireless-2011-11-22. I am using Ubuntu 11.10. Two different set of IEEE802.11n hardware:
1) TP-Link TL-WN821N AR9287 - rev2 USB dongles 2) Azurewave AR5008 (rev1) AR5BXB72 PCIe cards Things I did to get Over-The-Air experimentation going: a) Applied Chun-Yeow's recommended patch to enable the HW acceleration for ath9k (Therefore, didn't have to do nohwcrypt=1) b) Changed ath9k rate adaptation algorithm to minstrel in config.mk c) For (2), had to fix the ath9k filtering issue suggested by http://open80211s.org/trac/wiki/ath9kFilteringIssueFix (Otherwise it will form neighbors, but ARP request and replies won't succeed without the FilteringIssueFix) d) For (1), had to add support for NL80211_IFTYPE_MESH_POINT interface suggested by Javier Cardona on June 9th, 2011 (Surprisingly the patch was not there already at least in compat-wireless-2011-11-22) Then, I get following HT throughput.
