Hello, I am attempting to build an AP that can support airplay streaming between various mac devices. My current test bed is as follows:
Macbook Pro 10,2 (13" Retina), with an Airport Extreme (0x14E4, 0x10F) card, which is using the BCM43xx driver (according to system report). Apple TV Gen 3 (no idea what the wireless hardware in it is) A Jetway Mini-top: http://www.newegg.com/Product/Product.aspx?Item=N82E16856107081 It's running fully patched debian stable (wheezy), amd64. I have replaced the stock PCI Express wireless card with a SparkLan WPEA-127N: http://www.sparklan.com/product.php?func=view&prod_id=181 and added two antennas to the top of the case utilizing these: http://www.embeddedworks.net/pdetail.php?mn=assy&prod=assy085 http://www.embeddedworks.net/pdetail.php?mn=ante&prod=ante542 The darn WPEA-127N came world-roaming burned in to the EEPROM, so I modified the ath9k driver from the stock debian wheezy driver using: https://patchwork.kernel.org/patch/2249511/ (thanks Ben) and for good measure, also updated regulatory.bin for crda to map regdomain 0 to the US (where I'm at). Finally, my modprobe settings for ath9k are: options ath9k override_eeprom_regdomain=0 options ath9k nohwcrypt=1 I have successfully connected to the AP over a 5GHz channel utilizing HT40, and have working network connectivity. My hostapd.conf is as follows: interface=wlan0 driver=nl80211 ssid=aero hw_mode=a channel=44 ieee80211n=1 wmm_enabled=1 wmm_ac_bk_cwmin=4 wmm_ac_bk_cwmax=10 wmm_ac_bk_aifs=7 wmm_ac_bk_txop_limit=0 wmm_ac_bk_acm=0 wmm_ac_be_aifs=3 wmm_ac_be_cwmin=4 wmm_ac_be_cwmax=10 wmm_ac_be_txop_limit=0 wmm_ac_be_acm=0 wmm_ac_vi_aifs=2 wmm_ac_vi_cwmin=3 wmm_ac_vi_cwmax=4 wmm_ac_vi_txop_limit=94 wmm_ac_vi_acm=0 wmm_ac_vo_aifs=2 wmm_ac_vo_cwmin=2 wmm_ac_vo_cwmax=3 wmm_ac_vo_txop_limit=47 wmm_ac_vo_acm=0 tx_queue_data3_aifs=7 tx_queue_data3_cwmin=15 tx_queue_data3_cwmax=1023 tx_queue_data3_burst=0 tx_queue_data2_aifs=3 tx_queue_data2_cwmin=15 tx_queue_data2_cwmax=63 tx_queue_data2_burst=0 tx_queue_data1_aifs=1 tx_queue_data1_cwmin=7 tx_queue_data1_cwmax=15 tx_queue_data1_burst=3.0 tx_queue_data0_aifs=1 tx_queue_data0_cwmin=3 tx_queue_data0_cwmax=7 tx_queue_data0_burst=1.5 ht_capab=[LDPC][HT40+][SHORT-GI-20][SHORT-GI-40][TX-STBC][RX-STBC1][DSSS_CCK-40] #ht_capab=[LDPC][SHORT-GI-20][TX-STBC][RX-STBC1] #ht_capab=[LDPC][TX-STBC][RX-STBC1] macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 wpa=3 wpa_passphrase=[REDACTED] wpa_key_mgmt=WPA-PSK wpa_pairwise=CCMP country_code=US the various wmm and tx_queue parts are mostly unknown to me, as I came across them trying to determine why my airplay stream would not start if the encryption scheme was CCMP. After setting the above, it would start when the scheme was set to CCMP. As of right now, I get about 11MB/s (88Mbit/s), and that seems low. I was hoping to see something closer 200-250Mbit, but I don't really know what to expect between a published maximum (which I currently believe to be 450Mbit for this card), and a practical maximum. So, my question is...am I doing it wrong? Also, since the wmm and tx settings are mostly unknown to me, I've been trying to figure out what they mean, but have not located any useful resources. If anyone could point me in that direction, I may find that these settings are completely wrong for my hardware. Finally, if this is the completely wrong forum to ask this question, I apologize. This is my first dive into a linux AP, and I'm mostly still stumbling around blindly.
