Is anyone using a BeagleBone Black and USB Wifi as a WAP?  If so, what =
kind of throughput do you get on your Wifi?  I=E2=80=99m getting very =
bad network performance.

Hardware:

- BeagleBone Black rev C.
- Tried with two different USB Wifi Adapters:
	- Edimax N150 (small nub type adapter)
	- LB Link from Adafruit (https://www.adafruit.com/product/1030)
	- Both show as RTL8188CUS chips (via dmesg)
- Wired connection connected for access to my network and internet

OS:

-  Mostly with the most recent Beaglebone Snapshot of 11.0
-  A few quick tests with the 11. snapshot image

Connection Speeds:

- Using nuttcp (over 100Mbps ethernet) between the BB and another =
machine, I can get ~90+ Mbps in each direction  so I don=E2=80=99t think =
there is an issue with that part of the connection.
- Using the BB as a WAP and connection my iPad I see 1 to 5 Mbps down =
and < 1 Mbps tested via the Ookla Speedtest app. =20
- Connecting to my ancient Netgear WAP using the same app and test, I =
get roughly 10 Mbps in either direction with the same test.


Configs (pretty much taken right from the handbook):

/boot/loader.conf:

if_urtwn_load=3D"YES"
wlan_mac_load=3D"YES"

/etc/rc.conf (relevant parts)

ifconfig_cpsw0=3D"inet XX.XX.XX.XX netmask 0xffffff00=E2=80=9D
defaultrouter=3D=E2=80=9CYY.YY.YY.YY"
hostapd_enable=3D"YES"
wlans_urtwn0=3D"wlan0"
create_args_wlan0=3D"wlanmode hostap"
ifconfig_wlan0=3D"up"
cloned_interfaces=3D"bridge0"
ifconfig_bridge0=3D"addm cpsw0 addm wlan0 up=E2=80=9D

/etc/hostapd.conf

interface=3Dwlan0
debug=3D1
ctrl_interface=3D/var/run/hostapd
ctrl_interface_group=3Dwheel
ssid=3DREDACTED
wpa=3D2
wpa_passphrase=3DREDACTED
wpa_key_mgmt=3DWPA-PSK
wpa_pairwise=3DCCMP



Any ideas?  Is this just the limit of USB wifi on this board? =20


Thanks,
Chris
