AP limited to 5 clients on Cubietruck ?

rom · June 13, 2017

Hello,

I'm running ARMBIAN 5.25 stable with kernel 4.9.12-sunxi on my Cubietruck and I mostly use it as an AP.

I've installed the "hostapd" package from the official armbian repository and it works fine until I want to connect more than 5 wireless clients. The kernel module used is "brcmfmac" provided by the armbian-firmware package.

Is it an hardware limit and how can I bypass it if possible ?

The working default config provided with hostapd package is below:

ssid=ARMBIAN
interface=wlan0
hw_mode=g
channel=5
driver=nl80211

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0

logger_syslog=0
logger_syslog_level=0

wmm_enabled=1
ieee80211n=1
wpa=2
preamble=1

wpa_psk=66eb31d2b48d19ba216f2e50c6831ee11be98e2fa3a8075e30b866f4a5ccda27
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
auth_algs=1
macaddr_acl=0

noscan=1
#country_code=SI
#ieee80211d=1

Thanks in advance for your help,

Romain

Yes, limited within firmware. Can't do it.

Thanks a lot for the answer Igor as well as for your great work on Armbian !

Can anyone recommend a wireless USB adapter (n draft or better if possible) working out of the box to use as an AP with hostapd ?

Thanks again,

Romain

Try devices with the RT5372 chipset. It works out of the box with the NEO mainline and legacy, and because it's 2x2 MIMO you should see 50-70mbit/sec instead of the 30-40mbit/sec that comes from the 1x1 MIMO adapters. There's a compatibility matrix of our testing of a bunch of adapters against mainline and legacy if you want to consider more chipsets: https://github.com/ConnectBox/connectbox-pi/wiki/USB-WiFi-Adapters
