Increase receive buffer size.

by stonehkm / November 17, 2006 5:05 PM PST

My ISP recently increased the download bandwidth from 4Mb to 7Mb. However, my average bandwidth down remains at approx. 4Mb!
I ran some tests and spoke to Cox Cable, my ISP, and was told to increase my recieve buffer size in the registry. They all knew how to do it in Windows XP, but the instructions do not work for Vista RC2 32bit. I am running Vista RC2 x86 and my machine meets all requirements for Vista premium. Anyone know how to increse the receive buffer size in this OS?

Perhaps TweakVI?
by John.Wilkinson / November 18, 2006 9:07 AM PST

Really, no tweak should be needed at all in order to get surpass the previous 4Mbps connection speed so I'd be a bit skeptical. Regardless, you may want to try out the free program TweakVI, which boasts internet connection tweaks in its repertoire. I haven't tested it myself yet but hope to get around to it soon.

Well I tried it! The freeware version only makes access easier to features you can easily access from the control panel.
The internet speed feature is disabled along with many other features unless you subscribe to a paid version. While I am using a pre-release version (RC2) of Vista, I do not intend to pay for anything not designed and tested on the final release version.
I was hoping someone, maybe you, would know a path, through regedit, to increase the receive buffer size as the Windows XP method does not work. Thanks for the suggestion John!

Never done it before...

I've never had the need to tweak such internet settings manually, so I'm not sure what registry entries to look for. It really shouldn't need done, though, and shouldn't have any direct influence in the effective bandwidth. I would have them give you their instructions of XP and then either try it out on an XP partition or see if you can modify the instructions for Vista. (Most of the keys remain the same, so do a search with RegEdit.) In short, it sounds to me like they're holding a pair of duces so I'd want to call their bluff.
