Hello everybody, a few days ago I noticed that my Late 2009 Macbook seemed to lose its internet connection every few minutes just for a couple of seconds only to reconnect. I have no idea why this problem suddenly started occurring, I had not not modified any hardware or software. Strangely enough, this happens whether I use Wifi (at work) or Mobile Broadband via USB ( at home) so I don't think it can be blamed on the internet connection. Stranger still, I should probably not be talking of losing my internet connection but of not being able to access the internet: While again being in a few seconds of slump, I checked my Mobile Broadband Manager and it was not disconnected, upstream traffic was occurring! Just the downstream was at zero. I run windows with bootcamp on the same Mac and there the internet works without trouble. I have all the newest updates installed. Any advice is more than welcome!
