I've just installed Ubuntu 14.04 as second OS on my PC and I'm having a strange issue.
When I try to connect to internet I notice a progressive slowing in the network speed till it completely stuck.
Then to restart connection I need to reboot my router (it's a D-Link DSL 2542b), but the problem repeats after a while...
This is never happened using Windows, so I don't know if it can depend on Ubuntu or it's a problem of my router.
Can you help me?
