Hi, I stumbled upon a PSM issue when a hidden SSID is used. It seems that mac80211 is not going to power-save mode with hidden SSID AP's at all. As far as I can see the following happens: - When generally scanning, the AP is getting a bss entry with a zero SSID. - When associating, a probe-req is sent to the AP with the SSID, and as result a probe-response is received with the hidden SSID in place -> a second bss entry is created for the AP, now with the real SSID. - After association, mac80211 executes ieee80211_recalc_ps(), but does not go to powersave because the beacon-ies are missing. - A new beacon is received for the BSSID, but it updates the bss entry with the zero SSID, ieee80211_recalc_ps() gets called, but for the associated bss entry the beacon-ies are still missing. As result, the STA does not ever enter WLAN PSM. Anyone stumbled on this issue? -Juuso -- 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
