I connect to the internet via wifi for several minutes, and then it disconnects without telling me anything (the image of internet connections says I am still connected). I have to click in my wireless network to connect again for a small period of time.
When I use another computer with Windows my internet never turns off. I believe I have used this computer with other wireless networks and the internet never shuts down. But also I have had the same problem with other wireless networks.
I have to say that I do not have much experience with network connections. Thanks for the support Ubuntu community.
