Apologies is this should go to the ath mailing list, but we are not sure where in the stack the problem lies. On a 3.11 kernel, we are trying to create a AP host using the following hardware: driver (usb) ath9k_htc: Atheros AR9280 Rev:2 using htc_7010.fw firmware (extracted from debian unstable) After solving some regulatory domain issues by patching the ath driver, we can force the card into becoming master at 5 GHz. However, at 5GHz, the clients are isolated from each other (ARP request from one client are not seen by the other). When we switch back to 2.4 GHz the system works as expected. We need connection between the clients. Looking at mac80211/cfg.c, I see that host isolation is indeed an option. I printed the value of IEEE80211_SDATA_DONT_BRIDGE_PACKETS but it is false as expected. Can anyone tell me whether this is likely a problem at the mac80211 level or closer to the hardware ? Are there other settings that kick in a 5 GHz that would not at 2.4 GHz ? We are quite capable of modifying drivers but have little knowledge of wireless hardware. Any information would be much appreciated. Sincerely, Gertjan hostapd (v1.1) settings are: interface=wlan0 driver=nl80211 ssid=MSS-01 ieee80211n=1 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=1 require_ht=1 ht_capab=[HT40+][SHORT-GI-40][TXSTBC][RXSTBC123] wmm_enabled=1 hw_mode=a channel=36 country_code=US ap_isolate=0 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
