I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them.

On Windows, everything's working fine and I had no problems with this.

My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes.

My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure.

Is there a fix for this?

iwconfig

lo        no wireless extensions.

eth0      no wireless extensions.

There's a simple answer for this.

iwconfig said me that "Power management" is on. Which is causing troubles. To turn that off, simply put this into console

sudo iwconfig wlan0 power off
