    I had file vault on for some reason, so I couldn't boot into safe mode. It's decrypting now. Should be about 2-3 hours. I'll let you know how it goes after I boot into safe mode. thanks for the help so far...

    you are welcome.


    If link speed within safe mode is higher (100 Mbit/s or 1 Gbit/s) then you likely have some kernel extension installed, which for whatever reason significantly slows down the network stack.


    If link speed remains at 10 Mbit/s, do a hardware test by pressing D when restarting. If any errors are detected, take your MacBookPro to an Apple Store or an Apple reseller for a thorough hardware diagnosis.


    If hardware test shows no errors, reinstalling OSX from scratch is called for.

    Reinstalled OSX (10.8.2) Still doing the same thing. I should also add that I have an apple Tv plugged in (there are 2 ethernet jacks per room) It streams really quickly. I've tried plugging it in with the Apple Tv's cable. Still really slow


    My school's IT department is coming out in about an hour, so we'll see what they have to say

    Hi there,


    having tested every possible option, the only remaining conclusion would be a defective ethernet port on your MacBookPro's logic board.


    Maybe the IT folks can solve the mystery. I wish you luck


    regards, Chris

    I think it's actually an Apple problem. I test another friend's macbook pro, and he has the same speeds as I do. His is also a 2012 model. Also, I've been googling this, and it seems to be an issue a lot have

    unfortunately that seems plausible.


    try taking it to an Apple store and them test the link speed there. In any case it should get at least 100 Mbit/s if not 1 Gbit/s. If it doesn't, you at least have an official saying of a Hardware problem.
