Hi I can't set up Ralink RT5370 wifi adapter. When I run lsusb I get:
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. Bus 001 Device 004: ID 148f:7601 Ralink Technology, Corp.
So my raspberry sees the wifi adapter. I can't have problem with power because I use a 2A power adapter. My file /etc/network/interfaces is edidet as:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "Your Network SSID" wpa-psk "Your Password"
Can someone help me? Edit: Thank you to all guys, the problem was that I installed another driver, now everything is okey.(sorry)
