How a set of tweaks on a free web host became a 100,000-download tool, featured on TechTV and reviewed by PC Magazine.
2000: the free-host days

The first CableNut was two things. One was the Cablenut Speedup Program for Windows 95/98/ME, a small installer (v2.05, later updated to 2.5 and 2.52) whose cablenut.exe had a manual tweak screen. The other was a hand-written cablenut2k.reg patch for Windows 2000 that you installed by right-clicking and choosing Merge. Rick called the Windows 2000 patch a beta.
It lived on cablenut.performance.cx under the title “CableNut’s Tweak Land – More Cable Then @Home!”, built as a frameset. Every page ended with the same note: best viewed at 800×600 or higher.
On January 16, 2001 Rick posted that the performance.cx network would go dark on January 31 after its bandwidth providers cut the host off. Teammate JonG had already offered space on his university student account, and the site was moved before the deadline. Rick’s verdict at the time: faster anyway.
The benchmark

This chart ran on the CableNut 3.5 page in January 2001. Rick’s Windows 2000 test ran twice with default settings and twice with CableNut 3.5. The defaults averaged about 317,000 bytes/s (290,344 and 343,540). With CableNut 3.5 the average rose to about 447,000 bytes/s (429,425 and 464,551), about 41% faster on that 2001 connection. By spring 2001 the CableNut 4.0 software page made a more modest promise: improve your internet speed up to 30%. These were 2001 results; modern Windows tunes itself.
In the press
By far, the best ISP optimizer I’ve ever found is Cablenut.
The Screen Savers, TechTV: “Top Tweakers: Cablenut”
TechTV · The Screen Savers
April 2001. Picked as one of The Screen Savers’ “Top Six Utilities to Tweak Windows”, alongside X-Setup, Hare, MIE55SpeedUp, Diskeeper and WindowBlinds. The write-up promised your throughput “may double”, a 2001 claim. Traffic to the CableNut site jumped from 400–500 hits a day to about 7,000, and Rick found out why when a reader emailed him.
PC Magazine
Reviewed CableNut 4.08 in its “Connection Optimizers” roundup, next to Accelerate 2K2, BeFaster, Internet Rocket, ModemBooster and TweakMaster.
ExtremeTech
The honest review: a tool for experts who already know their TCP/IP settings, with little hand-holding, but preconfigured settings for cable, DSL and dial-up.

Chris Pirillo’s daily tech newsletter mentioned CableNut in early January 2001, just before 3.5 shipped.

Life on the forums
CableNut grew up on the broadband boards, SpeedGuide.net most of all. A few things that came up again and again (paraphrased, from threads between 2001 and 2005):
“Why are half the boxes empty?”
The most common question about the Adjuster. The answer: an empty box means Windows is using its default value. You only fill in what you want to change.
Tweaking takes a strong stomach
When one early 4.0 user saw his cable connection slow down, regulars reminded him that every system reacts differently. Tuning your own .ccs values was the whole point.
The magic number: 64240
The most-recommended receive window of the era: 44 × 1460, an even multiple of a cable MSS. Forum members handed out custom .ccs values tuned to each other’s connections.
CableNut or TCP Optimizer?
The eternal debate. The usual verdict: CableNut for hands-on control of every TCP/IP and AFD value, SpeedGuide’s TCP Optimizer for quick basics. Some ran CableNut first, then TCP Optimizer.
The Broadbandnuts and DSLnuts years
In spring 2001 CableNut merged into Broadbandnuts.com, a shared home for CableNut and a DSL help site. For the next twenty years the software, the guides and the forums lived under the broadbandnuts.com and dslnuts.com names.
- May 2001: Dannjr registers broadbandnuts.com, “home to Cablenut and DSLnuts”, with forums for help, tweaking, networking and security.
- November 2001: new forums break, the backups turn out to be almost empty, and the site goes back to its old boards for a while. The same update announces the CableNut MTU Tool beta.
- February 2002: the site names cablenut.com as the official CableNut address.
- August 2009: the forums hold about 29,600 posts.
- January 2021: the last archived snapshots show about 30,300 posts. The old site and forums closed around the end of 2021, and CableNut moved to WordPress (see the 2022 post).
The team
The CableNut team, as credited in the 3.5 release notes (January 2001) and later pages:
- Rick (“Cablenut”): webmaster, the tweaks themselves, and NSIS installer scripting
- Dannjr: DSL tweaks; he also ran his own cable and DSL patches site, and later proofread Rick’s articles
- JonG: the team’s self-described uber-geek, who wrote the CableNut Adjuster and hosted the site on his student web space
With special thanks to SpeedGuide.net, TweakFiles.com, Nullsoft and a SpeedGuide forum regular.
“We’re alive and tweaking”
By 2006 the team posted a thank-you to the fans who had kept CableNut going “since the first conception in 2000”. Future updates were unlikely, they wrote, but the site and forums would stay up for their supporters. The old forums closed around the end of 2021, but twenty years later the site is still here.
