I have a strange issue with that.

I downloaded the ad-blocking hosts file from the link given and changed 127.0.0.1 localhost to 127.0.0.1 RM696 localhost manually with kate (I'm on Kubuntu). Then I transferred the new hosts file to my Downloads directory and replaced the original /etc/hosts (I made a copy before).

Everything works fine except the fact that I am not able to access any website when I am in my wireless home network

What is really strange about this issue that I got it working back again when I changed my hosts file back to the standard one. When I tried out the ad-blocking hosts file again it didn't work again for me. But now my old hosts file does not work too! Any tips?

Edit: Well, obviously this could not be caused by the hosts file. there was some encryption error, I changed b&g to b and then to auto108mbps and now it is working again. Very strange. yesterday I downloaded some maps through my wifi...
