Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle down.
 

Hello
Had 30mb/s - Wed night - fri morning after upgrade.
Fri evening 20Mb/s max still 20Mb/s today.

Is the super hub working correctly.... I asume the 33000000 downstream figure would mean yes. but you can correct me on the power figures not being right or are they.
Or have I ended up in an over subscribed tier now with the old folks here down south taking to much BB..

The SH needs no time to settle down. There's only on way to measure your performance with any certainty and that's to have the SH in modem mode and either your own router or your PC wired to it. Then we can rule out the wretched thing which is known to be flakey in router mode especially if wireless is turned on.

Your downstream power levels are too high. If you has 8 channels (which you will in due course), those levels aggregated under the 3 dB doubling rule (you can look that up!) would exceed the 33 dBmv absolute input power level.

IMO your SH needs a 10 dB Forward Path Attenuator (VM engineer or eBay).

But there is something strange happening in that your upstream power is so high. If there was cable attenuation, the upstream would have trouble pushing through and would be high; but then the downstream would be low. But your upstream is high. If you ever see it at 55 dBmv or above, then things will slow down.

It could be high because it can't responde to keep-alives due to the high downstream power. So the first step is to put a 10 dB forward path attenuator on and see what happens.

And do please use modem mode if you don't want a whole can of whooppee what's wrong experience!

Yep got modem mode on, was not going to make that error. read that enough times.

Ok ordered a 10dB Forward Path Attenuator thingy, If it will avoid having to wait for engineer.

This is typical now ive spent <£8 its back to full download speed again now. with out any changes in the super hub.
Its like some one flicked the switch and changed me back to 30Mb/s from 20Mb/s
As Im now downloading again at 3.6MB/s OK.
This is going over my head for once as there has been zero change in the Superhub. Ill fit the thingy.. and see if there are changes.

edit : sorry I meant on tuesday when it arrives

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Has your powerlevels gone down now?

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

what are your power levels like now? Are they still +10?

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

yep infact they have all gone up but 1

up stream is exactly the same.

sorry
I wont have the 10 dB Forward Path Attenuator till tuesday due to bank holiday monday.
Don't understand how going up gets me full speed download again.

Edit OK Yep its gone again back down to 20Mb/s again looks like I will have to wait till Tuesday then as it is randomly swapping before I report back.
cheers till then.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Im betting It won't make a difference when you add the attenuator

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

If the tuners in the SH are affected by the high power, like there is crosstalk, or an amplifier is overdriven, then there will be downstream FEC errors (that are not pblicly reported in the SH Logs but which were reportrdd in the VMNG 300).

But yes, if there is congestion anywhere, the attenuator won't do anything other than prevent collapse when the SH is eventually provisioned with 8 DS channels.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

My SH was rubbish so I returned to 10meg from the 30meg that I had upgraded to , bin it quick !

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

OK seeing as i was getting emails when people post.
heres an update.
Now ive unsubscribed from topic the emails will stop.

Its randomly going from 20Mb/s - 30Mb/s type speed teirs.
Upload remains a constant 2Mb/s which is better than the 1Mb/s upload of 10Mb/s.
It was a free upgrade, No cost. It would just be nice to have FIXED speed again.

Missed the shipping window for Saturday so wont get the part till Wednesday.
Bank holidays suck.. they won't work them.

see ya wednesday.

Well I stuck the lump of metal on and got...

So yep moved to over subscribed tier.
Posts are being made from users who upgrade this week that CS are now saying they may not get the upgraded speed in their area when they upgrade. Looks like the training was altered for the second week after the new bundles.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

those power levels are perfect, nice

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

After doing a few, actualy a smegging lot of speed tests.
Ive got lower Ping (10% quicker but that might be just wednesday low traffic) and Lower jitter (50% less).

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

If you actually download something from a good big site what kind of speed do you get then?

I wouldn't just go on what speed tests to see actually speeds.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Just under 2.4 or just under 3.6MB/s as posted in 1st post = 20Mb/s or 30Mb/s tiers.
Never in the middle.
Its Wednesday so its 3.6MB/s as per first post.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Well its Friday evening again.
and the speed has not dropped :D
https://www.cableforum.co.uk/images/...2012/04/85.png
So thanks.If they increase the channels to 8 from 6 then that extra 100Mb/s of shared speed will hope fully stop the other users from over loading the connections. :cool:

Cheers (Hope to have high speed saturday as well.)

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

May I ask what website did you get that graph from as I would like to check my speeds as I upgraded yesterday

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Not a web site built in to OS of kubuntu.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

How did you get the free upgrade?


:)

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

ring up and ask for it

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Yep.

As it say on the Left under my name.
Rang and asked about the Free 60Mb/s upgrade that Users had been getting.
Was rejected buy CS for 60Mb/s upgrade as I did not Have the correct Bundle for FREE 60Mb/s upgrade.
Was offered Completely FREE NO COST AT ALL to me upgrade to 30Mb/s.
Free superhub, Free engineer, Free activation, Free collection of Old modem, Aka Free. SOLD.
Im On VM broadband again for 12 months.
As I live in Bournemouth not Christchurch, FTTC from BT does not exsist.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

I havent read the whole thread but they'll only upgrade you to what you are due. i.e if you was on 10 or 20 they'll give you a free upgrade to 30. If you was on 30 already they would have upgraded you to 60 and the 50s they are banging up to 100.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

The engineer can upsell you to 60meg for £5 extra, they've put you on L30

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

But thats not what others were getting :(, others got it FREE 60Mb/s not a fiver.:erm: completely FREE. ;)
He was likely upset allready as I don't Have coffee in the House... only Sugar drinks...

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Are you an XL or L broadband customer?

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Was L 10Mb/s
Thats not why I posted My reply. I posted because kandinsky wanted to know how I got my upgrade...

And still getting 3.6MB/s download even on sunday with out the liitle metal box. last week end hope fully will be a one off.

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

L customers don't get a free upgrade to 60 only xl30 do

Re: Did I upgrade to an unstable 30Mb/s or does this super hub take time to settle do
 

Yes I know that. I went though all that With customer services over a week and 6 days ago. ILL repeat I "ONLY POSTED" what "I DID" 1 week and 6 days ago.
Because I was ASKED to post how I got my free Upgrade.

The "SOLD" term is used when some one is happy with What is offered..

Back to topic... Of... if I got unstable 30Mb/s BB Upgrade
Final Test today Of the FREE upgade.
