I've recently had to go back to the superhub and since I have, my pings/jitter has been poor.. I've noticed that my Power levels are higher than when I was using the VMNG300 can someone confirm they are ok or if they need attention please?

My Superhub is in modem mode already

I've got a 10DB attenuator on the modem already..

down is high, up is low... call 150 from your VM homephone and get a tech booked to sort it out

I don't have a VM homephone :p

I just called them and got a discount and told there is high utilisation in the area which will be fixed by the 8th feb...

I asked the guy to check the power levels and guy says they are fine (This was india though)

call again and get a tech booked, get put through to appointments or better yet customer relations.. they will happily get a tech out to you.

Appointments say because there is an area fault they cant book an engineer?

wait until the faults been cleared. did they give an ETA or any info?

check your area...

They said apparently there has been a fault open since the start of Jan for high utilisation in Greater Manchester region.. Fix date is 8th Feb,

However I've not had a problem with ping/latency until I switched from my modem to the hub (In modem mode)

Appointments passed me to British faults who said they can't see an issue with power levels although the modem did reset and upstream is 32.5 now..

brilliant I'm the only 1 that thinks your levels are both high and low then :2up:

I thought at the most the maximum power levels should be about 7dbmv and for upstream that should be around 40+ so thenry is spot on.

i agree with thenry, downstream is too high for VM specs and upstream is way too low. I am surprised you havent been losing your connection. I would ring them back and speak to someone in the UK and explain that the fault isn't with your speed so it isn't going to be fixed with the capacity upgrades (directly), it is a power level problem which needs sorting. The irony is though that depending how extensive the work is for the capacity upgrades, it might indirectly fix your problem anyways.

The Downstream is high and would flag up when they rang in, but they should stay connected as we see levels way higher than that, may slow them down more than anything and the upstream is on the low side.

This is a case where the service tech should move your tap in the street cabinet to a higher attenuation - assuming your street cabinet is of that type. Otherwise the tech should add a 4 dB equaliser to pull your downstream down further and your upstream up.

Something like that.

Thats the problem.. I did speak to someone in the UK who passed me to someone else in the UK...

He said my power levels looked fine, one minute later my modems rebooted and ive got 0.5 more power on my upstream...

But they are all giving the "wait till 8th feb" treatment..

hmm, it ain't gonna happen dude. It depends on how forceful you want to be about it. If it was me I would ring up (staying nice and polite), explain what the problem is (power levels) and ask them what is happening between now and the 8th of Feb which makes them think it is going to solve your problem. If you put them on the spot like that are you asking them for information which they aren't going to be able to provide and hopefully it will force their hand.

The sad thing is that it might be policy to stop all tech visits while there is maintenance in the area because there is probably some sort of statistic saying that 90% of faults/symptoms are due to upgrade work when it is going on so they are quite happy to wait till it finishes to find out what the 10% of true faults are.

I already put them on the spot about it - Wasn't happening :p

Call to the CEOs office again?

Hmm, you say you should experience disconnections... my Upstream is at 30.5dBmV during the day and night depending on the temperature outside. My downstream power is near perfect at 0 to -1 to 1 on all the different channels. Weird.

Say ever since I had my cable installed, they put a rather short coax cable in.. can I get an engineer to come fit a longer one?

And on the side check the power? XD

8 Days later on the VM forum and still no reply... Pretty frustrating...

have you tried 150/151 again? try going through BB support then if unsuccessful on getting a tech booked call again and press 5 for thinking of leaving and rant on an unstable connection, you being told your levels are out of range etc.

My power levels have gone up to-day. There was an outage and since coming back on instead of being QAM64 they are now QAM256. Presumably in connection with the speed doubling?

There's still no actual problems as I still get 30Mbits.

Should I phone up?

your down levels are high.. could prove to be unstable. its up to you, see how it goes or call 150/151 to book a tech to lower them.

Hmmm, ig is a tricky one. I wouldnt want to tempt fate and if it is working ok i would personally leave it. that being said, the ds power levels are out of spec for vm so if you rang up they would send someone round to fix it

After a polite but frustrated post on the forum about other people getting responses, a mod flagged it for review and I got a message asking me for dates to book an engineer..
