I have an Acer Aspire One 722 Netbook running Ubuntu 13.04. It has a "Qualcomm Atheros AR8152 v2.0 Fast Ethernet" Ethernet controller. When I connect to the internet via a WiFi connection it works great. But sometimes don't have access to WiFi and must use a wired ethernet connection. When I use an ethernet connection, the internet connection seems to be flaky. About half of the time webpages will load. I have to keep reloading the page until it works.
