Sudden drop in speed from 1Gig

[MckeithyB]

I've recently upgraded to 1Gig. Today at 3.45 speeds went from 960Mbps to 3-4

I reported it, and apparently there's a problem with the modem (hub4) , although I'm not convinced it was even investigated. Anyhow an engineer is booked for Monday.

All the metrics on the modem status look good apart from the docsis 3.1 QAM1024.

Problem in my area (KT5) or genuine problem with the new modem?

Wired connection only.Modem mode. All the usual problem solving steps undertaken.

Cheers

Hi All,

For what its worth - today was much better.

Latency started to falter a little towards 4pm, then got better

Still the odd dropped packet, but otherwise more 'normal'

Mine was poor at 4:30-5pm but picked up again and is working at the speed it is meant to tonight. Lets hope its a permanent fix.

Doing better today than yesterday so maybe the fault has been found finally?

Hi everyone,

Using the details we have on here, we've been able to get a fault ticket raised to investigate the broadband issue and it's been logged under F009132366. The estimated fix time  is 02/07 and thank you all for your patience whilst we work on the fix.

Thanks,

Lisa

Thanks for letting us know.

As indicated above, it looks like yesterday was significantly better, but there was the occasional spike

Its it still worth keeping the engineer appointments ? Apparently my 'levels were out of spec' but I don't know which ones, or by how much. 

[MckeithyB]

Well, unfortunately the engineer did turn up at 8.20 but the nobody heard the doorbell. Only realised when I checked the cameras later. Could have called any of our listed phone numbers, but....

I'm still of the opinion that the recent issue was nothing to do with the hubs.

Anyway, speeds are consistent and stable at the moment - might not always be the headline speed, but they're ok. Whether it represents good value is another matter. I would happily sacrifice half my download speed for a double the upload, but i'm getting what is advertised.

Regarding what VM thought was the problem initially - to my uneducated eye, the 3.0 power levels look good. What about docsis 3.1 though. Is -7dBmV within spec ?

Hi @MckeithyB

Can I check how your service is now? An outage in the area which was logged is now closed, how is your service after this? 

Regards

Hi There,

Its been good as far as I can tell. I'm able to drive the connection at up to 950Mbps with my kit, but all seems well.

Now, if VM can prioritise upload bandwidth next, that will make it really useful 🙂
