Tweaking Cabel Modems

[wickedone]

Please if some one can help, AnandTech had a post on there web page about a week ago on geting the most out of your modems. If anyone can rember this site, have good infoon it or can direct me to there favorite site on it I would be thankful.😕

If it was something illegal, then it probably got deleted.

But I'm doing a search on it right now.

🙂 Well a very good WinXP tip is to go to run and type 'gpedit.msc'. Then go to 'Admin Templates' -> 'Network' -> 'QoS Packet Scheduler'. Here you should find 'Limit Reservable Bandwidth'. You want to enable this and set it to 0.

😱 WinXP likes to reserve 10% (IIRC) of your total bandwidth for .NET or MSN or some other crap, this means you only get 90% of your true modem bandwidth for your own uses which really sucks. Change the above setting and this makes the bandwidth Windows reserves = 0% and as such you have all of your bandwidth as you should have in the first place ... HTH!

😀 Just a quick query, I'm using a 3com Etherlink 10/100 PCI TX NIC (3C905B-TX) for my Broadband Internet Access, in the device properties I have:

802.1p Support: En/Dis
Down Poll Rate: 8/64
Flow Control: En/Dis
Media Type: HW-Default/Auto/10Full/10Half/100Full/100Half
Rx Checksum Offload: En/Dis
Tx Checksum Offload: En/Dis

😱 It is 'Down Poll Rate: 8/64' which puzzles me most. Anybody have any info or links on these settings?

If you are referring to "uncapping" a modem, forget it. You ISP will catch you eventually and give you the boot.

This place has some great registry patches to improve your up/down speeds.

That's if you're lucky...if you're unlucky the FBI shows up at your door and kindly asks you to get in the back seat of one of their cars..

Thanks for the link John. 🙂 I had been to that site awhile back, but did not add it to my favorites.

This is wrong. QoS only reserves that bandwidth if you have a QoS enabled network card and a QoS enabled switch/hub/router, which 99.9% of home users do not. In this case, it does not reserve any bandwidth, and your connection remains as it was with any other OS.

QoS is not some .NET or MSN thing. Its a way to designate the importance of packets, so the most critical packets will reach their destinations before the less important ones, etc. There's more to it than that...but this really isn't the place to go into it.

😉 Hey cool, I admit that networking is not my strong point even though I studied it at University as part of a module it kind of fell out of my head after the exam LOL! Isn't QoS an API and as such any program (like MSN Messenger or .NET stuff) can deem itself a 'high priority' and as such limit all other communication to only 80% or 90% (whatever is set as default)?

😀 Anyway all I can say is that I noticed a significant improvement after doing this tweak and it can do no harm, worth giving it a try at least ...
