Topic: OpenWrt and USB Wifi Hotspot with Ralink RT5370

The content of this topic has been archived on 15 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi, I have a wifi usb dongle with Ralink RT5370 Chipset installed on OpenWrt (which relies on an Atheros CPU) .
I'd like to establish a direct WIFI connection between the Atheros and my PC, so the new dongle must work as hotspot.

The installation of the related packages on OpenWrt was fine and the OS recognized the new dongle.

opkg install kmod-rt2800-lib kmod-rt2800-usb kmod-rt2x00-lib kmod-rt2x00-usb

Since my Atheros has an integrated WIFI I tried to disable the internal WIFI and enable the new one via Luci Interface. and modifying /etc/config/wireless but I didn't solve the problem. My pc tries to connect to the wifi (new dongle interface) but gets no IP. I think it's  an OpenWrt's DHCP server problem .   Have you got some tips? Which files do I need to modify ? Thanks
