Estou trabalhando em um INTEL NUC 5i7RYH rodando o Ubuntu 16.04LTS. Eu estou fazendo algumas coisas de robótica e tenho um Lidar conectado ao NUC através da Ethernet. No meu laptop funciona bem, mas no NUC, assim que eu abro um novo terminal ou o Eclipse (por exemplo), parece que o aplicativo detecta que a conexão Ethernet está perdida e tenta se conectar novamente.
Após pesquisar na rede, parece que pode haver um problema com o driver de LAN da Intel.
De fato, o Ubunto 16.04 está executando o 3.2.6, enquanto a Intel lançou a versão 3.3.6 do e1000e.
Eu corro make install e a nova versão está localizada em:
/lib/modules/4.10.0-38-generic/updates/drivers/net/ethernet/intel/e1000e
Meu problema é o seguinte, embora eu use sudo rmmod e1000e; modprobe e1000e , ainda tenho a versão antiga.
E se eu tentar:
sudo insmod /lib/modules/4.10.0-38-generic/updates/drivers/net/ethernet/intel/e1000e/e1000e.ko
Não funciona:
sudo modprobe e1000e && dmesg | grep e100
