I have upgraded from 200mbs to 500mbs and after changing from super hub 2 to hub 3 today, my ethernet speed (if it manages to connects) has gone from from 200+mbs to 30 - 40mbs download and at one point as low as 0.87mbs. Even after switching it on and off and resetting the hub the ethernet will connect from time to time but most of the time it won't connect at all which results in having to use wifi on my computer which is no where near as fast as using ethernet, at most I can get up to 87mbs download through wifi.
