( ) but all instructions (i've found) regarding installing this haven't worked I get a great signal with Win7 and horrible with mint, if at all. None of the 15's work with this wifi card and only the 32bit "14" editions will actually hold the wifi connection. I'm running out of ideas for what could be causing this and would appreciate any suggestions.Tried every distro. I've checked that power management is set to off, and also that tx power is set to 20 dbm. I've also added the appropriate firmware file to /lib/firmware. I've compiled in the driver module rt2800usb - as this is the underlying chip on the RT5390. I'm using a buildroot Linux image with Kernel 3.12.9. In startup I can see that the drivers and firmware file have been loaded properly too, with no errors, and the udev rules I'm using to rename the network interface are also working fine. If I run iw dev scan I get no results, but no errors either, the return value of iw is 0. All the processes which should be running ( hostapd or wpa_supplicant) are running as they should be, but it seems like the card isn't transmitting properly. But then if I reboot the router the RT5390 won't show up as an access point, or won't connect to another access point. Then when I try with a new RT5390, the first time I boot everything works fine. I can switch between these two modes and there are no problems. The RT2571 card works perfectly well, I can set it up as an access point, or connect to other access points. I'm working on a wireless router and have been set a task to support some wifi cards, namely the Ralink RT5390 and RT2571.
