Hi there,
Long first post (sorry)
I've been having intermittent issues for months with my Infinity, on activation was getting sync of 79995/20000 and all looked fine, was performing brilliantly.. For a couple of weeks. Then the resyncs began for no apparent reason, DLM woke up and I ended up with a 25Mb sync speed - was running a Homehub 5 (Type A) at that point.
Raised multiple faults throughout the saga, had multiple engineer visits:
Visit 1 - Engineer installed new drop wire and SSFP, line test was clear, DLM reset, full sync restored - for a week or so
Visit 2 - Engineer attended while I was at work, replaced my Hub with one he had in his van (?!) This rebooted itself after an hour or so and never came back, factory reset wouldn't work, so mithered the helpdesk constantly until they sent me a Type B as a replacement (I'm on a Huawei cab)
Once that arrived sync drops reduced drastically, however monitoring the connection via the noddy Helpdesk page showed me huge noise margin fluctuations and changing attenuation, quiet line showed nothing, but sync speed was slowly dropping back to sub 40Mb - upload sync was <1Mb, logged another fault.
Visit 3 - "Engineer" visited, did a PQT and said he couldn't do anything. He mentioned aluminium, also tried to tell me my sub 1Mb US sync was "because it was half-term", claimed the sync speed at the time was the best it could be (43Mb)
Once I recovered from Visit 3 I escalated and got another appointment sorted.
Visit 4 - Boost engineer visited, tested line at my house and the pole, got a hoist out to replace a cover that was missing, still seeing a lot of errors, went to the cab and then sorted a lift and shift out due to a "faulty port"
Once this was sorted, here's where things get really weird (for me anyway)
He tested sync at the house while he was waiting for the lift and shift to complete, told me his JDSU had just had a firmware upgrade for vectoring, he got an 84Mb sync..
When my "profile had been applied" got a seemingly solid 68/20Mb sync
Over the moon with that, considering the bull I'd been fed by the other engineers - although his 84Mb sync perplexes me..
Since then the drops have returned, but apparently only in the evening.
I can instigate one by picking up the phone and using it. Snap, crackle & pop obvious and gets worse and worse until sync is lost.
I can track the SNR loss on the "Helpdesk" page of the Hub, until it loses sync.
It will always then resync at an abysmal speed and then recover on its own a short while later.
See below:
After lift and shift
5. VDSL uptime: 0 days, 17:28:24
6. Data Rate: 19999 / 68206
7. Maximum Data Rate: 21945 / 68651
8. Noise Margin: 13.8 / 6.2
9. Line Attenuation: 0.0 / 16.6
10. Signal Attenuation: 0.0 / 0.0?
16/07/15 - HR fault? Resynced while on phone
5. VDSL uptime: 0 days, 00:14:01
6. Data Rate: 19999 / 47642
7. Maximum Data Rate: 18638 / 36771
8. Noise Margin: 3.9 / 2.0
9. Line Attenuation: 0.0 / 17.7
10. Signal Attenuation: 0.0 / 0.0
16/07/15 - resynced on its own 19:16
5. VDSL uptime: 0 days, 00:08:18
6. Data Rate: 19999 / 68776
7. Maximum Data Rate: 22393 / 69584
8. Noise Margin: 14.1 / 6.4
9. Line Attenuation: 0.0 / 16.6
Now, I suspect this is some sort of HR fault, it seems worse when it's wet too.
So, instead of raising as an Infinity fault this time, I've logged as a voice fault in the hope they'll be thorough enough to find the issue. Engineer is coming tomorrow (AM) so noise probably won't be present.
So (and if you got this far well done) how would our resident experts approach this, have I done the right thing?
Also, how would the boost engineer have got an 84Mb sync??
Cheers
