I'm using a netbook with ubuntu while traveling and in a lot of places, the network seems quite unstable.
As when you travel, you change a lot of accomodation (ok, it depends ...), for most/all wifi connections, I want to force some settings. One of them is dns servers (eg google or opendns) and not using local dns.
It does not seem possible currently. only per connection setting, no global one.
Another thing, wifi signal is unstable and after some time, NM bugs you with a dialog. I want to have an option to say unlimited try, eventually with a notification, but don't depend on an interaction as I know signal is cut regularly and it's not the password.
Any hints ?
