Change your DNS to OpenDNS in ubuntu

April 30, 2011 2 comments

If you want a fast and reliable DNS server, try OpenDNS.

Just edit /etc/resolv.conf


$ sudo vi /etc/resolv.conf

And modify the values to the ones of the OpenDNS:


nameserver 208.67.222.222
nameserver 208.67.220.220

And that’s all, you don’t need to restart, simply save the changes.

Install Edimax Wireless 802.11b/g (EW-7318USG) wifi dongle on ubuntu linux

April 26, 2011 1 comment

I’ve moved at home to a room with no internet connection. I had an Edimax wifi usb adapter (EW-7318USG) that stands for being compatible with Linux OS.

The documentation and the installation CD is only for windows 😦

I plugged in the USB to check the type of adapter:


$ lsusb -v
<pre>Bus 001 Device 003: ID 148f:2573 Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter</pre>

That is a Ralink RT73 chipset:

So I installed the module and now I’m ready to surf!

$ sudo modprobe rt73usb
[sudo] password for miquel:
$ iwconfig
