MacBook slowing down my internet connection.
I have had sluggish internet speeds since my UVerse install on Tuesday this week and after troubleshooting, I have now come down to the fact that every time I connect my MacBookPro to my network (wired as well as wireless) the connection speeds on all other devices (iPad, PC and MacBookWhite) are slowing down from 16+Mb and 33ms ping to 1.5Mb and 300-600ms ping..
I have been able to reproduce this using speedtest.net and I can cleary see that as soon as I unplug the MacBookPro from the ethernet cable or disconnect wifi, the speedtest performence will improve dramatically.
Has anyone seen this ???
