I have configured TX1 to act as Access Point with the help of the following thread:
The hostapd.conf file I use has this content:
interface=wlan0 ssid=test hw_mode=a channel=48 wpa=2 wpa_passphrase=test12345678 wpa_key_mgmt=WPA-PSK country_code=US wmm_enabled=1 ieee80211n=1 ieee80211d=1 ieee80211ac=1 driver=nl80211
and I have successfully started the AP mode and I am able to connect devices.
Unfortunately thought, it seems that bandwidth is limited to as much as 54MBit/s. I have tested with several devices and it doesn’t depend of the proximity of the devices, their number or even interference from other networks. This is also the case when using 2.4GHz configuration (as the above one is for 5GHz).
On the other hand I can conclude that this is not an antenna issue, because when configured as client, the TX1 can connect at speeds >300MBbit/s for the 5GHz case.
Has somebody achieved higher speeds when connecting to TX1 configured as AP? Or should this be a configuration issue or even hardware limitation of the wifi subsystem?
*Note: tested it on Linux for Tegra r24.2.1 and the latest r28.2 release hoping for a driver update - no improvement!
