Re: Ethernet/Internet not working

I suggest you sort the ethernet connection first.

Ensure ethernet cable is firmly connected to RPi and router/hub

Disconnect WIFI adaptor

Type: ip link show eth0

Type: ip addr show eth0

Type: ip route show

Show us the output of the three commands

Please let me know if the...

Re: USB Sound Card via USB Hub VS Rpi USB connector

Hi all

I tested the USB Hub by using it on a desktop running Centos 6. The audio quality was good. So it cannot be the USB hub.
