. . . the Downstream SNR Margin dropped to 0.1 dB, not sure how you've still got a working service.

In the past, I have seen a HG612 maintain synchronisation with the DSLAM when the SNRM has gone negative. I watched it go down to -1.9 dB and it was only when it reached -2.0 dB that it finally "let go".

[matt12321]

Just had re-sync

[matt12321]

Speeds lower, errors lower - just need DLM to find the sweet spot in the middle now.

US seems slow.

[William Grimsley]

I think there's still a fault with your line.

I wish we could change SNR Margin on FTTC, I'd have it at 0 dB.

[NewtronStar]

Puzzled were the 10Mbps came from on the downstream it didn't come from the attainable as it stayed around 28.9Mbps even when a disturber has turn off their modem the SNRm would increase and so would the attainable rate. and why was the modem set at such a low SNRm in the first place 

[William Grimsley]

Think the modem synced when there was a noise spike.

[NewtronStar]

Sounds plausible the DS & US SNRM went low just as the modem finsihed it's resync and the result is higher sync rates with very low SNRM.

[William Grimsley]

Now, that gives me an idea, I need to time my next manual resync...

[matt12321]

I reset the modem and seem to have restored my US to where it should be at least.

I'm happy enough (for now) with 28/3 if it's stable - once I've sorted my LAN then hopefully will resolve the AV500 FEC issues.

Anyone else had experience with the Unifi products? I'm impressed with the WAP I've got, so thinking about adding a second upstairs and replacing Homehub 5 with the Unifi Security Gateway.

I've been away for quite a while so I was just reading the early post on this thread.

You said you "just plugged it in to the HH5".

Is the HG612 plugged in to the phone socket?

Then the HH5 is behind the HG612?

[matt12321]

Yes - everything seems to have stablised a bit now, I'm still using the AV500 powerline adaptors but they don't seem to be causing massive problems. I've also tried separating power/data cabling as much as reasonably possible.

The order of things is:

Master socket - HG612 - WAN socket on HH5 (with Wifi off) - Unifi WAPs

My original plan was to replace the HH5 with another router, but not found out yet if the Ubiquiti range is fully compatible with BT Multicast yet.

[Bowdon]

Yea, thats the problem with 3rd party routers, the BT Multicast function.

I'm glad to hear things have stablized.

I'm not a fan of powerlines but I can see how useful they are. As long as your getting a good connection then if you want to make any changes then at least its in your 'realm' to do them.

[matt12321]

I'm trying to get rid but in the short term there's no other option without resorting to wireless bridges but that may then just reduce overall Wifi performance for little gain.

Unfortunately in an existing older house - running data cabling everywhere isn't that easy!

[burakkucat]

My original plan was to replace the HH5 with another router, but not found out yet if the Ubiquiti range is fully compatible with BT Multicast yet.

If you take a look at this post, it might help you to decide if an Ubiquiti EdgeRouter Lite would be appropriate for your needs.

[matt12321]

If seen that one but there was no mention of whether he was using it for Youview/BTTV so assumed not.

The ERL and USG seem to be the same hardware but with different UI - advantage of USG is that it's managed from the same portal as WAPs whereas the ERL is more from command line and is less 'home' user friendly.
