Bug Description
I have spent hours trying out dozens of solutions from the ubuntuforums and askubuntu, nothing seems to help. Ethernet cable and plug (in office wall with many ethernet plugs available) switched to test if this is the problem.
My internet connection sporadically and regularly drops. Sometimes it is that webpages take a long time to load, or never do. Sometimes this can be fixed by reloading the page, sometimes this does nothing. In those cases the only solution is to either disable and enable networking or click on the supposedly connected wired connection I am using to get it to reconnect manually. In both these cases the connection is usually back within 5 seconds (very rarely I have to do this twice).
I have reinstalled network manager and resolvconf, I have disbled ipv6, I have edited NetworkManager.conf (along with a few other things that all don't seem to work). Generally the connection is stable for a long time following a reboot, but once it starts dropping out, it can stay stable for a half hour, or 2 minutes, and there seems to be no way to know.
Sometimes trying to load a page or an element in a page will trigger network manager to react to the loss of connection. What I mean is that in this case both skype and dropbox show that they have gone offline, and the network manager icon appears to look for a connection. This then happens within 5 seconds (as when I do this manually) and the connection is back. Again, this then can hold for a half hour or only 2 minutes, or anything in between.
