I guess u are the lucky 1, do you??
Yes, 1xx kBps download speed is normal for 1Mbps subscribers. But that was long time ago.... (in galaxy far far away ==")
U might STILL lucky bcos tmnut haven done anything on ur connection hahax

Can you provide any screenshot of your Line Attenuation & SNR Margin with /without the ferrite?

Yes, I agree with u. Ferrite bead act as a resistance to eliminate EMI and RFI, therefore increase speed stability and avoid bandwidth loss. Ferrite bead cant boost/break speed of the package you have subscribed since the user speed is restrict by ISP, not copper wire =) Ferrite bead is just to ensure you get the best speed for wat you pay.

Here you are

Before everyone goes out and buys ferrite cores, keep in mind that they will not do anything for the majority of people. ADSL signals are differential-mode, i.e. equal and opposite polarities on the pair, whereas ferrite beads only filter out common-mode noise, where the signal is equal on both wires in the pair.

Modems already have ferrite beads inside. Adding extra cores on the cable will only make a difference if you're in a terrible RF area, e.g. there's a large AM radio station transmitting near you, swamping the front-end of your modem. ADSL runs at around 30kHz to 1.1MHz.

Choosing the wrong type of core will affect its performance too, if any. There are three main materials in use - mix 43, 64, and 77. Mix 43 covers 1MHz - 1GHz, which is what you'd want if you really wanted to try an extra ferrite core.

Ferrite cores are usually only used to prevent EMI leaking *from* devices, not to block them from entering devices.

Aluminium foil around the wire won't do anything unfortunately!

You can get free ferrite bead/core from unused cable, it is not necessary to buy to it if you have 1. Thx for your info. Yes, ferrite are used to prevent EMI leaking and the absorbed energy is converted to heat and dissipated by the ferrite As you know copper is the must have element for antenna. Thus it is always attract some "extra" signal from external environment. Ferrite does help regardless more or less. That's why the ferrite core is added on the telephone wire and not RJ45 / RJ11 wire.

I have telephone cables made with ferrite core, from my laptop packaging. Comparing to ordinary cables without ferrite core, it has no SNR or attenuation difference.

The place u live is so healthy XD

get it from explode Power Supply aka PSU, any broken old motherboard, or any board/cable that provide, this time we make an Green Earth and Recycle the computer component,

it is really working, now my DS margin up for 2db and US margin for 1db, whereas attenuation for DS is down for 1db

yes.. not to day i add 2 ferrite, not total 3 ferrite...

Any wire will receive RF, but the interference will be common-mode which will be ignored by good modems, unless you happen to be in an RF-poor environment that swamps your modem's front-end. That's why I'm saying, ferrite cores don't magically make your line more stable - you must be swamped by stray RF at just the right frequencies first, before ferrite cores will do anything.

It's like saying eating panadol will make you feel better. It won't - you must have a headache first before panadol will make you feel better.


hmm RJ11 is the plug used on CPE telephone wires...
