1Mbps upload speed only on work laptop?

At home I was getting 150+ Mbps download and between .90 and 1 Mbps upload speed consistantly at the library I got about 30Mbps download and 25 Mbps upload. All the other devices in my home are getting the 10 Mbps upload exept my laptop that is needed for work. I had a tech over and he changed out the equipment and we still encountered the same problem with the laptop, still getting better connections on other networks and my other devices still getting the correct upload speed. 

Anyone know why this would be happening?
