So I'm using my new MBP on Stanford University's wifi network and it's pretty fast and everything, but the upload speeds are terrible on this new laptop. I tried uploading using my old HP laptop and it was just fine but my MBP gives me less that 1 mbps, thought the download speeds are around 18-20 mbps (used speedtest.net). Actually uploading something on mediafire gives the same result; it takes about 10 minutes to upload something thats 5MB. Does anyone know how to fix this? It's my first Mac, and I love it for everything other than this issue.
