Background: I own a 2008 MBP running 10.8.2  and while at home, I use a  hardwired ethernet connection rather than WIFI. I recently upgraded to  WEBPASS.NET for my ISP which has brought ultrahigh speed connectivity to  my condo (200-400+ mbs) . My wife's iMac constantly runs download speeds of 300+mbp and  upload speeds of 150+mbs


on my MBP i am getting anywhere from 50-100mbs/ 20-35mbs. (yes, I know  those are great speeds but I am supposed to get at least 200mb/100mb.).


What I have done: I have tweaked the network setting in preferences to  be manual 1000mbs, full duplex, mtu-standard. But this did not help.  Neither did tweaking a setting in firefox regarding a dns setting. That  did nothing either.


I have used Chrome, Firefox and safari with not luck.


BUT ...


if I connect my wife's iMac to my rj45, the iMac still generates the  numbers listed above. So the problem is not the line or the router but  the MBP...which is according to documentation is capable of 1 gb speeds.


I have spoken with my ISP (Webpass) but all of their stuff is working is the 2008 MBP.



I even reinstalled 10.8.2 with no luck.



Any suggestions besides buying a new MBP?  Thx!
