Hello, I have problem with download speed - for example, I start downloading a file in Safari with 2.3 mb/s, after approximately 30 seconds speed starts to decrease - 2.1, 1.9, 1.7...till some kb/sec. And this problem is not only with Safari, the same is with Fugu. It's a hardware problem or software? Wireless router works great. MacBook 4,1 , Snow Leopard with latest updates.
