There's something odd happening. Sometimes downloads (from the browser, from the updater, from synaptic) simply stop working, like there were no connection, sometimes even pages stop loading. But what's funny is that before this happens, everything is normal, pages loads, Youtube works, even downloads work. But usually, after I'm downloading something big, that download stops, and it's like I lost my wi-fi, but I haven't. And it all comes back to normal only after I reboot. So defenitely it has something to do with the computer, not the wi-fi, because my phone everything else continue to work.
