I run dual OS (Windows 7 Pro.) and Ubuntu 10.10

When at home I can connect to my network but not get internet on either OS.

I spoke to housemates who gave me two DNS adresses to use (only works on Windows), these are 4.2.2.1 and 4.2.2.2, which work great, BUT I am under the impression that these should not be used, is this true? Also, when I go to college/my mum's house or my girlfriends place I have to remove these adresses in order to connect to the internet - annoying. Is there a way I can set it to only use these DNS addresses when connecting to my home network?

I am unable to enter these DNS addresses into Ubuntu, this is most likely due to my lack of knowledge of the system but the OK button is greyed out when I select manual under IPv4...


Internet works fine everywhere other than home on both OS.

i'm not exactly sure why your house connection is requiring you to put in DNS info to begin with. that stuff SHOULD be coming to your computer automatically if you're using DHCP on the connection. if you're not, then i assume you're also having to put in a static IP as well as the DNS?

where are you entering these addresses?

why do you think they shouldn't be used?

one way or another, if you're having to use static DNS settings, try 8.8.8.8 and 8.8.4.4 (google dns, available from everywhere)

Nope, just DNS. Works without Static IP

Entering the addresses in the network adapter settings.

Read somewhere that they shouldn't be used for some reason or another...

Will the two google adresses work on any network?

they should. again, if the network in question was set up correctly you shouldn't have to enter your own DNS ever anyway

Yeah the problem is it was set up by a housemate (who has no idea) and I'm not keen on altering settings incase I mess their connections up. ALthough I may log in and check it's correct...
