Got a new air, was fine for the longest time, upgraded to ML and ever since it goes up to 1.2mb/s then goes all the way down to 400-700 kb/s. This is not acceptable. I'm paying for a 3mb/s connection and my PC has no trouble attaining that. My modem/router options are fine. This is on OSX's side, any idea? I'm so sick of this happening. It happened with my MBP all the time. Got this new air and it was fine, until now. Pretty sad that I have to pray for 1mb/s when I'm paying for 3x that speed. Nothing but bad experiences on recent Macs.
