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
