Hi, I'm a new to the mac world, having recently got a new 15" MBP with the Core i5 Processor. I've found some very strange behaviour that I'm trying to get to the bottom of, if anyone can help? When I have a torrent client running (utorrent or transmission), I get frequent HTTP timeouts in firefox and Safari. This happens regardless of whether the torrent client is actually transferring data. When I click on a link, in firefox I can see "connecting to www.google.com" for a long time - sometimes the link loads, sometimes it just times out. This happens 80%+ of the time. I should say that a PC on the same (WiFi) network is able to load these same pages at the same time, so the issue isn't down to connectivity. Has anyone seen this before? I phone apple support and unsurprisingly they weren't willing (so far) to go beyond checking the basics: - Creating a connection profile - Deleting my networking config - Rebooting on the Snow Leopard disk and checking filesystem permissions - Trying from a different account on the same machine. The guy on the phone told me he could go no further - I don't accept that an O/S should allow this to happen, no matter how errant an application might be, but I said I'd try to resolve this myself before I called back and argued the case. My next steps are to see if I can see anything in Netstat or wireshark. So ... If anyone has any experience or suggestions, I'd love to hear them. Thanks.
