Came across this earlier this morning

Cant confirm personally as I don't have any HG612 to test with.

In reply to a post by mixt:

Does it have to specifically be Build C030 SP08 ? I note on the Kitz site, hg612_unlocked_sp10_firmware is mentioned.

Cheers.

If you want the latest HG612 fw which is compatible with G.INP then yes you need Buiild 30, SP08. SP10 is from an older build (28) and doesn't support G.INP. Going from old to new:

B027SP06 or v27.06
B028SP10 or v28.10
B030SP06 or v30.06
B030SP08 or v30.08

Thanks!

So I think my plan to attempt to sort this mess out will be as follows.

1) Downgrade with Zen in May back to 40/10. This kicks off a new 12 month contract, and will kick off a DLM reset/retrain period. I don't expect this to solve any of this G.INP nonsense however as the ECI modem I have is obviously not compatible with G.INP. If, however, it does, I'll probably just stick with my existing ECI modem. Maybe BT will push out a firmware update to all ECI modems by then (and pigs might also fly).

2) Request during the downgrade order process, and as part of ordering a brand new package/contract, that Zen ship me out their free £60 Technicolor TG589vn v3 modem/router, which according to this, does support G.INP.

3) Figure out how to put the thing into bridge mode. Found this (all be it foreign).

4) Hope all that works and I can sync back at 40/10 with normal latency again using the Technicolor TG589vn v3.

5) If none of the above works, I will look at the HG612 route.

I've added this thread to my favourites - will update again in May once I downgrade (for those who are interested on the outcome).

Ta.

But we are talking about BT here, and I'm pretty sure they have moved to the stance now of not being responsible for the end user modem anymore. Have a read of this: http://www.revk.uk/2014/10/bt-losing-plot-on-fttc.html

On Monday an OR engineer replaced my HG612 with another (brand new), with no quibble. His suggestion in fact, as he couldn't find any reason I couldn't connect with my ISP despite having a G.INP connection to the cabinet.

I have the same problem since 31st march.

latency doubled and sync down to 65Mbit

Is BT actually doing anything to sort this mess out? Do they even have a firmware update for the ECI modem?

Really bad packet loss it seems tonight for me, at least on the graph

I know it's kind of off-topic, sorry.

I think you have hit the nail on the head and from my experience it was always better to have the same BCM chipset matched with the BCM Huawei cabinet.

It's hard to say what the cause of this is, other than it's not a generic problem with the thinkbroadband BQM platform. My BQM shows no packet loss, though I'm using a different ISP with different backhaul, I'm probably on a different exchange to you, and I have a (locked, so it should get firmware updates from Openreach) HG612 modem.

In reply to a post by D_an_W:

if it was originally the intention of OpenReach to supply a Huawei modem if on a Huawei cabinet and vice versa which would have probably prevented these issues but it instead turned to a "whatever was in the van" approach.

I think it turned into "fit an ECI modem and put the Huawei on Ebay"
