Has anyone used this device successfully?
It looks like it can support concurrent mode: http://www.daveconroy.com/turn-your-raspberry-pi-into-a-wifi-hotspot-with-edimax-nano-usb-ew-7811un-rtl8188cus-chipset/
However after changing the hostapd binary on the rPi it still doesnt provide an access point.
@Robert_Hurley if you use our image from https://www.astroprint.com/downloads you don’t need to do that. Out image is already configured for that family of wifi chips
Thanks for the quick response, but I already was using the image you linked to and was unable to get the access point to work by default. I could connect to the astroprint over ethernet, but the option to start the hotspot isn’t present either.
Was the Ethernet cable connected during the installation process ?
I first tried it without the Ethernet cable connected and didn’t get a hotspot. I noticed while connected to it over Ethernet that the settings were trying to use wlan1 whereas the only device according to iwconfig was wlan0
If you only have wlan0, then either the WiFi HW is not the right one or the driver is not ours. Did you modify anything from the standard image?
Also, if the software finds a valid connection to the internet (i.e. an ethernet connection), it won’t try to open the hotspot.
Using everything from the standard image, I was only able to get wlan0 to show up. I modified the settings udev settings to rename wlan0 to wlan1, and was able to get and connect to the access point. However scanning for wifi networks fails.
So it would seem RTL8188EUS doesn’t work and only the RTL8188CUS will?
