Every now and again my eth0 will go crazy and says can not go into scanning mode. I'll not be able to connect to my AP unless I restart the whole computer. For some strange reasons it can detect my AP sometimes but it cannot connect to it unless I restart my computer.

It will sometimes say eth0: no IPv6 routers present in dmesg. I'm connected but I have no internet at all.


I've tried

ifconfig down
iwconfig eth0 mode managed
and when i try "ifconfig up" it will say device / resources not ready.

The card wouldn't work until I restart my computer. I have tried switching on / off the wifi switch but I still get the same problem.

Anyone know a better way to restart the card instead of the whole computer?

You can try;

ifdown eth0
iwconfig eth0 mode managed
ifup eth0

Or, as root; service network restart

You might want to edit your config file for the wireless device, for example;

TYPE=Wireless
DEVICE=eth0
HWADDR=
BOOTPROTO=dhcp
NETMASK=255.255.255.0
GATEWAY=The router's internel IP address here
DHCP_HOSTNAME=
IPADDR=
DOMAIN=
ONBOOT=no
ONHOTPLUG=yes
USERCTL=yes
IPV6INIT=no
PEERDNS=no
ESSID=
CHANNEL=1
MODE=managed
RATE=Auto
