I have an aluminium macbook that I got just over a year ago. Internet was fine until about a month ago. Now it's completely sporadic. Sometimes it takes a second to load a page, sometimes it takes 5 minutes. Without rhyme or reason. I can open a page I've been loading for ages in a new tab and it will load straight away. We have three other computers (pc's) on the network and they're all completely fine. I've done speed tests. They've ranged from 13kb/s to 2mb/s. It is ridiculously annoying and I have no idea what to do. I don't know why it's changed, I haven't changed any settings. Everything else, word, itunes etc. runs fine. I asked this a couple of weeks ago with no result, hopefully someone will be able to help me out now.
