Good evening!

Joined up as I've been looking here over the past couple of weeks for information, now I'm a little stuck!

I've seen some of the things you guys have been speaking about here and this kind of thing is way outside my basic knowledge of this area, I'll be honest!

Basic information:

BT Infinity 79/20 package
HG612 with latest unlocked firmware
PFSense 2.2.2

Essentially, I wanted to install a PFSense firewall to our network and to do this obviously couldn't do it properly whilst the HomeHub5 was acting as the modem. So I bought the Huawei HG612 3B version. Install went well, everything was working and saw some fantastic results, I believe due to the G.INP that started to work a few hours after install. Speeds before with the HH5 were 65Mbps and would fluctuate up and down quite highly, upload was OK at 18mbps. After install and the next day, running the same speed test saw it hit 75mbps almost instantly and would be pinned there for the whole test, barely any fluctuation and upload remained similar to before (I'm fine with that). It's been working as good as this for the past week or so.

However today I noted the network being a little slow, I ran a speed test and only getting around 20mpbs now - strange I thought, so restarted the firewall and HG612, came back and it was a little better but not much?

Looking on the traffic logs on the firewall and barely anything is going in or out so I'm fairly sure nothing else in the house is using up the bandwidth.

Any suggestions for what I could try? Could BT notice that the device they installed is no longer in use and be doing something? Or could it just be a bad day or some work going on?

Any more information required please ask, I know how to SSH to the modem and get some basic stats from it but that's about it, however I can get anything you need with your guidance!

It is highly unlikely that BT have intentionally done anything simply because you have swapped modems.

There is a current issue when using G.INP compatible modems when connected to ECI cabinet DSLAMS, but I wouldn't imagine that would be the cause of such a significant speed drop.

We would need to see your connection stats to even start suggesting anything.

Do you have any from before the speed dropped?

Any more information required please ask, I know how to SSH to the modem and get some basic stats from it but that's about it, however I can get anything you need with your guidance!

You could try the stats logging/graphing programs HG612 Modem Stats (Windows only) from here:-
http://www.freewarefiles.com/HG612-Modem-Stats_program_84567.html

or DSLStats (Windows or Linux) from here:-
http://www.s446074245.websitehome.co.uk/downloads.html


Alternatively, running these case-sensitive telnet commands once logged in to BusyBox would provide the minimum details we would need to see:-

xdslcmd info --stats
xdslcmd info --pbParams

xdslcmd info --vendor output data would confirm whether you are connected to a Huawei or ECI DSLAM.

Have you got the HG612 configured as a modem and pfSense doing the PPPoE ?

What's pfSense running on?

[Eniqmatic]

Thanks very much for the swift reply.

I believe I checked already and confirmed that I am on a Huawei cabinet, although there is a possibility I read it wrong. I did have the stats before when it was good but then lost them I'm afraid.

I just re-ran a speed test and got 30Mbps and 17 up which seems unaffected:

I hope that is everything you were after for just now, I can do the Windows logs in the morning if you would like them also.

[Eniqmatic]

Have you got the HG612 configured as a modem and pfSense doing the PPPoE ?

What's pfSense running on?

PFSense is making the connection through PPPoE yes that's correct. PFSense is running on a dual-core server spec mini-ITX build with 4GB of ECC, 2 Intel NIC's and an SSD.

[Dray]

Did you kill BTAgent on the HG612?

[Eniqmatic]

I believe the BT Agent is killed by default on the GUI version of the latest firmware but could be wrong? How would I go about checking?

[Dray]

You will need to log into the HG612 BusyBox shell via Telnet and use the following command

    ATP>sh
    # killall -KILL start btagent

Then do it again

# killall -KILL start btagent

It should be obvious from the 2nd time that it is killed

[Eniqmatic]

OK, did it there and first time nothing came back, second time it said nothing to kill. Does that mean it wasn't killed in the first place? I re-did a speed test and it climbed quite slowly to 52. Coincidence?

Edit: Nevermind, got 39 after

[Bald_Eagle1]

I hope that is everything you were after for just now, I can do the Windows logs in the morning if you would like them also.

Yes. Those logs with a few more hours worth of stats would be useful.

One or two of the stats you have posted give rise to some concern, but as the connection had only been up for around 2 hours when you obtained them, it's probably too soon to provide much in the way of meaningful comment.


The good news is that you are connected to a Huawei DSLAM & that G.INP is active.
The connection is also in sync at 79999 Kbps / 20000 Kbps with a little SNRM to spare.

The Bearer 0 & Bearer 1 INPRein values do suggest a 'noisy' line though, as does the Bearer 1 delay value.


 

[Eniqmatic]

OK so shall I give it till the morning and post the stats again? It's my mistake really for immediately restarting it I guess, habbit!

Forgive me for being a noob but what does the bearer values mean? How would you resolve a "noisy" line?

[Bald_Eagle1]

I re-did a speed test and it climbed quite slowly to 52. Coincidence?

Edit: Nevermind, got 39 after

Are the speed tests being conducted wirelessly?
If so, they won't really be truly reflective of the connection's capabilities.

Speed tests should be done via a wired connection for more accurate results.

[Dray]

Yes the first time it was active and you killed it.
The second time it wasn't active so there was nothing to kill.

You will have to kill it again after a resync.

[Eniqmatic]

No I'm wired 1000mbps to the firewall. I do have a fair amount of knowledge of networking, just literally zero on the broadband side of things with terminology etc so forgive my ignorance. Thanks very much for the help so far both, much appreciated.

[Dray]

Did you also disable TR069?
