I've been on the 80/20 trial for a couple of days, and noticed that my 6-year-old laptop (with Windows XP) could only get speed-test results of around 60-65Mbps, while a new Win7 machine could get 75Mbps. It turns out that older Windows variants are more likely to be limited by the configuration of their TCP stack - which makes it a software limitation, rather than a hardware one. I used the information on this webpage, http://www.speedguide.net/analyzer.php, to check the effects, and the "SG TCP Optimizer" application on this page: http://www.speedguide.net/downloads.php to help choose the "Optimal" settings. In particular, the size of the "receive window" was a key factor, but I also learnt that my MTU was set at a stupid value (1300). I applied the "optimal" settings for both the wireless interface on the laptop, and the wired interface, and both saw improvements: The wireless (old, G) went from 23Mb to 26Mb. The wired went from 64Mb to 75+.
Those are speeds I get using Firefox as a browser. Chrome still seems to be woefully hit & miss

heh indeed. Have to remember that XP has been around over 10 years - Broadband wasnt really commonplace upon release - let alone anything else There are several 'TCP Optimisers' etc - but id recommend making a mental note of the original settings - as its not uncommon for things to make a mess. Also its worth noting to others that Windows 7 monitors and updates it TCP Stack settings itself (and does a pretty good job, which is why that isnt required on the Win7 box) Regards
