very slow internet on 11.04 on advent laptop

Asked by Graham Strachan

Hi, I installed ubuntu 11.04 the other day (which is excellent by the way) Im using chrome as thats what im used to from windows vista. The wireless internet surfing is really slow. It connects to my modem no problem. When i run sudo iwconfig wlan0 power off it does get much better but still not as good as it did on vista. Can anyone help me as its ruining the whole ubuntu os experience for me.

thanks

Graham

ok try:

gksudo gedit /etc/resolv.conf

Delete all the text and add these 2 lines:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save the new file, close gedit then retry the web. Is it better?

No you will need to put the settings in network manager, set the interface to DHCP (address only) then set the DNS to:

8.8.8.8, 8.8.4.4

This will make the setting stick between reboots, basically your ISP's DNS is slow. Changing the DNS to google's public DNS has sped things up for you
