Received FEC

i have just started geting Received FEC : 221 errors, what is FEC

Forward Error Correction. May mean interleaving is on.

mooch.

Sorry not to clued up on broadband terms, what do you mean "May mean interleaving is on" and is it anything to worry about, also just noticed my speed has just dropped by 1 Meg

Not too hot on this myself

All I know is, when I was on fast path I had no FEC errors. Interleaving leads to FECs....just correcting packets received. Nothing to worry about as it's usual with interleaving.

I lost a half megabit of synch when interleaving was turned on, also the latency is increased (ping times), by how much depends on what degree of interleaving is used.

Don't know enough to tell you more.

mooch.

"Another aspect is interleaving. This is a technique that allows some of noise to be tolerated more easily. It is combined with forward error correction (FEC). An interleaved line cannot achieve quite the same level of max sync speed as a non interleaved line (presumably because of the overhead of the FEC). Interleaving does increase the latency on the line (the time for packets to be sent/received). There are different levels of interleaving and correction which can be used, but BT only use two settings, on and off. Non interleaved mode is called fast mode"

This just started happening in the last two hours, I have had a lot of problems lately so I have been monitoring my connection closely its dropped from 8096 to 6671 in the last couple of hours and I have started getting errors. I will keep an eye on it.

Exact same here, I will have to check if they have put me on interleaving, but since saturday I have been getting FEC errors, but my sync rate is still the same tho, but I will go check to see if they have put me on interleaved.

yup the [censored] have put me on interleaved when there was nothigng wrong with my downlaods to start with, i been with this company 4 days and i already starting to hate them, bring back the gpo

how do you check?

I had to hook up another router, as it doesnt show you in the hub, if it does i couldnt find it.

I had to sync up with another older router and check what that says as it has uber amounts of info compared to the hub.

If the home hub has a Broadcom chipset (which it presumably has, as other posters have mentioned it can accept the SNR/margin tweak), it may be available using telnet (if you can find the command).
Does DMT work with the home hub? (As this places the words "Fast path" or "Interleaved path", etc., by the side of the modem picture, on modems/routers that can provide this information).
