i bought me an edup ep-n8531 nano wireless usb stick to upgrade my netbook, which has an built-in rt3090 that causes problems.
Background: The rt3090 is working under lubuntu 13.04, but it has connection losses. I already tried different solutions, also compiling the driver myself, but nothing worked how it should. I don't want to hack my way to get wlan working anymore and bought the stick. My router is wireless n draft capable and other devices are working pretty fine with it - windows machines and android smartphones.
The stick is delivered with a driver cd for several platforms. There's also a linux driver. But the driver is a single file called '2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V220.127.116.11_DPO'. How do I install it? Just put it under lib/firmware? Can anyone help me?
lsusb says the chip is an ralink rt5370. The staging driver works but has very very poor performance - only works with the router in the same room.
If the chip causes bigger problems with linux, i could use it for some old pc and just buy another stick. The edup stick was about just 7€. Could anyone recommend a good piece of linux wireless hardware?
