Speed issues
 

I'm having weird speed issues, this being from around 50mb to 140mb fluctuations... I've just upgraded to 152mb/s as well!

Only thing I can tell it is that the signal may be incorrect as I've had this issue before. From reading it looks ok to me but just want to double check before I call them and act clever and say it's a signal power issue!

P.S Do the errors look particularly high or is it just me? Been on for like 2 hours 45mins.

Re: Speed issues
 

Your levels are fine, there are no Timeouts which is good, I would call them as it sounds like over-subscription as the levels are in spec.

Re: Speed issues
 

Apparently over the last three days utilisation has been over 80% and peaks of 90%+... Right now it's sitting at 82% according to VM but cannot be raised as an issue until it carry's on like this for a week because of KPI and Ofcom etc.

Re: Speed issues
 

WTF?

Re: Speed issues
 

Entirely normal process:

From VM's OfCom May2015 UK average then 152 Tier
is 104.7Mb (8-10pm peak weekday) and 135.78Mb (24hr daily) which infers some of 1400 SamKnows panellists are experiencing utilisation and/or degraded service anyway?

Data rates are not going to map exactly with utilisation levels even if every affected user has a convenient, morereliable 24x7 hourly sampling ala SamKnows anyway! :(

eg I still have an open downstream utilisation issue since November(with monthly credit) but June still yields 144mbps monthly average to date. ;)

The increasing utilisation trend was evident from my Aug/Sept SK stats but didn't exceed VM escalation thresholds till 14November2014. Worst case the monthly average never dropped below 130mbps so realistically it never dropped down to even 120 tier headline rates and therefore personally not worth the stress of additional toy throwing. YMMV clearly..... especially if peak time is your only convenient usage pattern! :(

Re: Speed issues
 

Whoah, that's actually gotten a lot worse since I last checked. IIRC last time VM were hitting around 75-80% of the provisioned rate at peak times

Re: Speed issues
 

I usually only compare against the headline rate(152) and not the provisioned rate(168.96) so Nov 2014 Peak Time (8-10pm) was between 76%(115) - 82%(124.5) of headline speed and it's been trending down each month since..... :(

One could infer that 152Tier take-up is still exceeding VM's network upgrades again as lower tiers don't appear to be affected as much.....

Re: Speed issues
 

Yup it has, most of my area is Virgin anyways. If you try searching for a Wi-Fi connection trust me your list fills up with lots of VM's.

But yeah, they have said call back on Monday to see if this has been logged as an outage.

Do you know how long it takes a resolve a utilisation issue? I'm getting speeds of 30-60mbps..

I have fumed at 1st Line at VM because they say it's my network.. Second line agree with my saying of utilisation. I've told them "Do not say it's my network as it's a piece of art with 2Gbps uplink to the goddamn SH."

Setup as SH ==> Switch ---> Clients

= - is two ethernet cables to that box
-- - is one ethernet

I might use the 14 day moneyback and go back to the 100Mb service.

Re: Speed issues
 

My area has been having issues since December last year and the fix date keeps getting pushed back. The only thing keeping me on 152mb is that they credit my account £15 each month for loss of service.

Speed is around 20-40 most nights and 100-152 off peak

Re: Speed issues
 

More than I get on my 12Mbps ADSL 24/7.

Re: Speed issues
 

I get higher around 40-60 and off peak I get a solid 100-140... I did some adjustments and got my power levels closer to the 0db mark... Currently at 1.65db AVG.

Re: Speed issues
 

Just called them today and they said there isn't an actual issue because utilisation over last 2 days is under threshold.. Probably because of the sun?

So the day I reported they said it's an issue now they're saying it isn't... WTF :S

Re: Speed issues
 

I just called them up and they said that the utilisation issue has been looked into and resolved.. Wtf!?!?!?! They fixed it in a week? I know people waiting for a year..

Re: Speed issues
 

Depends what caused the utilisation and when it was originally reported. You might have reported it a week ago but it could have been noticed and picked up months ago, or you got lucky and a scheduled upgrade came at the right time.

Sometimes utilisation issues are actually faults, as noise on the line degreades the network to the point where it loses 75% of its bandwidth, but the operator just sees a graph with utilisation at 99%.

Re: Speed issues
 

Getting issues again, they're saying may be something up with the line to the cabinet...

What I'm getting right now is this http://www.speedtest.net/my-result/4482889510

Re: Speed issues
 

I've definitely been having utilisation issues myself. Speed has been hovering around the 10Mbps mark for the past couple of weeks now where I live. I can get the full speed if I test around 3AM though haha.

Re: Speed issues
 

Same... Engineer was called out for me and he said a rewire will help.. WTF? db and everything is perfect! I did do a messy job but it wasn't a bodge!

Re: Speed issues
 

Yeah I really doubt the issue is with the cabling - check the SNR on the SuperHub page as well - low SNR can be related to it but it can also be due to a fault with the cabinet.

With that said, utilisation problems seem to be common lately unfortunately.

Re: Speed issues
 

yeah, they have been so good over the last year or so and it appears they have dropped the ball again. I am wondering if they have left it to focus on the upstream and they think they'll fix it all when they revisit it for the upcoming downstream upgrades
