I been having network problem with my Macbook lately and just wondering if anyone else too. Basically, when I run wireless I can browse the web flawlessly, but download speed only reach 3mb half of my max speed. If I run a cable, I can download at max speed, but browsing the web is choppy. Sometimes it takes forever to load, sometimes it doesn't load at all, and other times it's fine. 3rd generation macbook running leopard and a D-link router. I don't think it's my router cuz I have a pc that connects with a cable and everything works fine.
