[SOLVED] what is the Linux terminal command to enable wireless?

omega341991 · 05-30-2012, 06:43 AM

There is an option in the taskbar in Ubuntu named "Enable Wireless"
How can i enable and disable this option from the terminal ?

I have already tried the commands

ifconfig interface_name up
ifconfig interface_name down

These have no effect whatsoever.

please reply

You need to use iwconfig instead of ifconfig for wireless.

iwconfig then the interface name should do it. Are you using DHCP assignment or static?

When you use the "Enable/Disable" wireless does it actually turn your card off or does it just disconnect from the router? If you want to turn off the card rfkill is what you want. I believe "rfkill block wifi" to disable and "rfkill unblock wifi" to enable should work.

When i use iwconfig , this is the error that i get

root@ubn1# iwconfig wlan0 down
iwconfig: unknown command "down"

If i dont give "down" ,it just lists the wireless devices

What should i do?

Those commands just disconnect the wireless, do you want to disconnect or actually turn the card off?

It's workung now. Used a combination of rfkills and ifconfig
Rfkill refreshes the network and ifconfig down temporarily downs the network

Problem solved

Thanks for your help
