ralink 148f: 760b pânico do kernel do driver mt7601 no Ubuntu 14.04

Question

A nova placa de rede sem fio não pode ser acessada

Bus 001 Device 005:ID 148f:7601 Ralink Technology, Corp.

Eu baixei o driver MT7601U DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 do site da Mediatek compilação corretamente após a instalação do driver para se conectar a uma rede sem fio. Mas uma vez que a página da Web é o sistema aberto, apenas caiu. Dmesg em pânico antes que eu tivesse problema resolvido encontrar esperança

Answer 1

Sugiro que você remova o driver com defeito:

cd ~/Downloads/DPO_MT7601U_LinuxSTA_3.0.0.4_20130913
sudo make uninstall
sudo modprobe -r mt7601Usta

Agora, vamos tentar um driver diferente:

sudo apt-get install git
git clone https://github.com/porjo/mt7601.git 
cd mt7601/src
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta

Por favor, deixe-nos saber se funciona como esperado.

Você compilou o driver apenas para a sua versão do kernel atualmente em execução. Quando o Update Manager instala uma imagem linux posterior, após a reinicialização solicitada, recompile:

cd mt7601/src
make
sudo make install
sudo modprobe mt7601Usta

Por favor, guarde o arquivo e estas instruções para esse tempo.

    

Answer 2

Isso funciona para mim, kernel Linux 3.19.0-28-generic

git clone https://github.com/porjo/mt7601.git
cd mt7601/src
make
checkinstall
dpkg -i *.deb
