I have a problem similar to this : While using internet on ubuntu, all other computers get bad internet connection
So the problem is, whenever I log onto Ubuntu Internet, all other computers Internet speeds goes down drastically. We have 20 Mbps download and 2 upload. However, when I log onto Ubuntu I can still get this on this computer but all other computers go to about .2 Mbps upload.
When I log into Windows on the same machine the Internet works fine on all other computers. I tried the fix mentioned in that post i.e. I tried "sudo iw reg set US" in vain.

dmesg output is pasted here: http://paste.ubuntu.com/5987128/ . One thing I have noticed is after I do the iw reg set US it appends the following to dmesg output:
