Get help and discuss anything related to tweaking your internet connection, as well as the different tools and registry patches on the site. TCP Optimizer settings and Analyzer results should be posted here.
I am having serious broadband issues so I signed up to the forum and have been running through some of the tweaks.
I have ran the TCPOptimizer and the SG_Vista_TcpIP_Patch.cmd. I am on Virgin Media's XL package in the UK (which boasts a 20MB line) and got the following results.

I understand that RWIN can't be manually set using Windows Vista but am fairly sure that it is the reason for my slow downloads. Is there a way to remove the restriction? Does BDP limit (200ms): 699kbps imply that I can only download at a maximum 699kb/sec ?
I am using Netgear WGR614v9 wireless router but still think I should be getting higher speeds than I am.

Did you uncoil the excess cable?
Any other coiled power cables nearby?

Also, my uncle just bought a new laptop and I tried downloading the same file on this computer and on his laptop (which incidently was placed further away from the router) on this computer I averaged 320kb/sec whereas on his laptop i averaged 1.4Mb/sec. Is it possible that my old wireless NIC just isnt up to it?
I might go buy a wireless NIC today or tomorrow. Can you recommend a particularly fast model for use with Vista Premium 64? Also, am i better of using an internal NIC or a USB dongle?
