Post your FTTC line stats & unlocking info

On another note, I think I'm going to have to revert my modem to being in my network room rather than the socket where the line comes into the house. Basically as I can't be bothered to run a cable between it and the room where my router is. I'm getting really bad jitter due to using the Homeplugs.

The spikes in latency are me uploading a lot of data but you can clearly see what it was like before the uploading.

The router is on a different subnet to his computer, how is that ever going to work? Or am I missing something? Is he trying to put the firmware on the HG612? He needs to directly connect his computer to the HG612, ignoring the router.

This was my point about not needing to change the ip of the router because its should not be connected for the steps anyway. It would be like trying to get your neighbour to change the IP of their router so you can flash your modem that has nothing to do with it.

Run the cable its worth it!

My modem is downstairs with a cable that runs upstairs to the router and i have no issues

I have a cable already going from the network room to upstairs where my gaming PC is, but I've managed to hide it, not sure I could do the same to where the modem is unfortunately. I need to run another to my iMac in the living room as I hate wireless!

Surely you haven't read the previous posts I've wrote. I have done/tried that already!

Montegue said:
pulled the power cord from the modem, pulled one cat5 cable out from the Asus router which goes straight to the PC and plugged that into the LAN2 socket of the modem, no other cat5's in the modem at all expect one in LAN2 that goes to the PC LAN.

Which if needs describing, Modem - Lan 2 - cat5 lead from lan2 of modem directly going to PC Lan socket. No router involved at all.

I think we might have a fault.

Upstream SNR dropped from 6 to 3.8dB on the upstream during the day, within a few minutes. It would perhaps explain the slow upstream sync?

The other thing is that I have swapped to another router and my attenuation has dropped from 23 to 18dB. I know it can vary a tiny bit but surely it shouldn't vary that much?

I'm on a 40/2 package with Plusnet.

I recently found out my cabinet is Huawei, so I bought an unlocked HG612 3B from eBay.

Having plugged that in, I can now see from the line stats that there's a 30% difference between my 'Max' sync rate (36120 Kbps) and my actual sync rate (24997 Kbps).

When FTTC was first enabled, I was getting over 30 Mbps (I think I saw 3.9MB/s as my max rate). Since then, it has dropped to 22 Mbps. Installing the Huawei modem has seen a jump to 23 Mbps.
Line has generally been very stable, haven't had any drop outs other than the very occasional overnight blip when, presumably, DLM is doing its thing (once in a blue moon).
Is it worth speaking to my ISP and asking for an IP/DLM profile reset? Especially as my new modem can talk G.INP with the cabinet (though I don't know for sure if my cabinet is enabled for G.INP - it was enabled for FTTC a year ago).

FTTC has been available at our cabinet since February. We signed up from day one and seemed to sync at 44Mbit and 10Mbit up. We've had Openreach out several times and each time the sync rate drops! We're over 1km away from the cabinet I believe.

Can we get any more out of this line?

Sparx · 19 Jun 2016 at 23:40

You can see from the stats your actual/max sync are at the limit.

Your line can now only achieve 32Mb up and 6Mb down, presumably due to cross-talk.

Gonna have to wait for G.fast mate.

Meatball · 20 Jun 2016 at 08:39

No G.Inp enabled yet either yet we're on a Huawei cabinet with a HG612.

bloody "fibre" broadband :mad:

Uhtred · 6 Aug 2016 at 21:26

I started with Infinity just over 4 years ago, then went to Sky fiber and now plusnet fiber. I still have the original BT provided HG612 3B and tonight I've just flashed it to the latest firmware so I can get G.INP, although from the look of my stats that isn't enabled as I'm an ECI cab.

I've also moved my modem 20 meters away from the master socket with a run of CAT5e. I haven't noticed any drop in speed and I can happily get 75mb in speed tests.
