I use an odroid (a rasberry-pi like mini-pc but more powerfull) as a Wifi access point for my smartphone and my camera since quite a long time. I forgot that my USB Wifi dongle was compatible with Wifi N (only on 2.4Ghz), so my hostapd config file was :
[code]interface=wlan3
ssid=Barbette-Chambre
hw_mode=g
channel=11
bridge=br0
wpa=2
wpa_passphrase=YOURPASSPHRASE
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
wpa_ptk_rekey=600[/code]
Here is the speed result with iperf :
[ 4] local 10.0.0.44 port 5001 connected with 10.0.0.175 port 48727
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.2 sec 18.4 MBytes 15.1 Mbits/sec
Normaly, this should be 56Mbits/s, but we know wifi is crap…
And to enable Wifi N :
[code]
interface=wlan3
ssid=Barbette-Chambre
hw_mode=g #Yes, this is not an error. Wifi N builds on top of G 😉
channel=11
bridge=br0
ieee80211n=1
wmm_enabled=1
country_code=BE
ht_capab=[HT20][HT40][SHORT-GI-20][SHORT-GI-40]
ieee80211d=1
wpa=2
wpa_passphrase=YOURPASSPHRASE
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
wpa_ptk_rekey=600[/code]
And the speed result is now :
[ 4] local 10.0.0.44 port 5001 connected with 10.0.0.175 port 48754
[ 4] 0.0-10.1 sec 30.6 MBytes 25.4 Mbits/sec
Better, but still not the 150Mbits/s of wifi N… But it’s better !
