Arduino Yun Wifi Hotspot with Ralink RT5370

Hardware Arduino Yún

Hi,
I've just bought a wifi dongle with Ralink RT5370 Chipset.
The installation of the related packages was fine and Linino recognized the new dongle.
opkg install kmod-rt2800-lib kmod-rt2800-usb kmod-rt2x00-lib kmod-rt2x00-usb

I tried to disable the internal WIFI and enable the new one via Luci Interface and modifying /etc/config/wireless but I didn't solved the problem. My pc tries to connect to the wifi (new dongle interface) but gets no IP. I think it's Linino's DHCP server problem . Have you got some tips? Thanks

@rockeronline00,
Yes. Why are you turning off a perfectly good wifi?

Because I'm building an Arduino Yun-based quadcopter and Arduino's Wifi sucks... only 5 meters -.-

@rockeronline00,
then add an antenna and turn up the power.

Hi Jesse,
thanks but I have already read those posts on external antenna, and as you could see, there's no possibility.

So as I posted above, I'm trying with a dongle Wifi since OpenWrt recognizes it.
My problems come from OpenWrt's DHCP server.. When I enable the dongle (and disable the internal antenna) DHCP doesn't work anymore .
So my PC finds the new network (of the new dongle wifi) but can't connect due to this problem

Do it at your own risk! ( back up your own data)

/usr/bin/reset-to-factory-anyway

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

cd /etc/modules.d

mv 24-rt2x00-lib 22-rt2x00-lib
mv 26-rt2x00-usb 23-rt2x00-usb
mv 27-rt2800-lib 24-rt2800-lib
mv 28-rt2800-usb 25-rt2800-usb

reboot Yun

mv /etc/config/wireless /var  
wifi detect > /etc/config/wireless

nano /etc/config/wireless

config wifi-device  radio1
...
option disabled 0

reboot Yun then test

it does not seem to work anymore. The arduino freezes as soon as the wifi dongle is enabled. Did anyone managed to make it work?

/usr/bin/reset-to-factory-anyway
reboot

is very important. and follow rest step carefully.

Disable internal radio might help.

nano /etc/config/wireless

config wifi-device  radio0
...
option disabled 1

@clynamen,
the person with original post did. And several other people also.

Make sure to follow SonnyYu's instructions. Make sure the dongle is on tightly. A loose dongle will cause a weak electrical link and the software will stall and freeze.

I actually didn't realize the post was so recent, and I though that an update caused a break. Thanks for your information, I'll retry again
