100M 5 VM Engineers visited - problem still exists

imaxtec · 08-02-2012, 18:41

This morning a senior engineer visited my property with his service laptop. i explained all my ground level problems.he confirmed that i am only getting speed between 30meg to 60meg and its not stable.

In peak time My UBR is always below 30% so that didn't effect my speed.

He totally denied story of 100meg tech support team (which is they are claiming that my area is 100% ready for 100meg connection and i should receive solid connection and also they confirmed that there is no planning or upgrading work due on my area)

Senior engineer said that i am on docsis 3.0 which is i am linked with 20meg and 50meg connection server

Right now VM is only focusing the 50meg people. 50Meg server is mainly designed to supply powerful bandwidth to 50meg customers and 20Meg customers.

100meg is new thing they are still working on it,for the time being they hooked the 100meg customers with 50meg server. that's why 100meg customers is getting unstable connection.

VM's main target is to doubling the speed to all customers, for that there are lots of ground works to be completed.

Also he confirmed part of the speed doubling project before end of march they are upgrading all 50meg people and 100meg people to docsis 4.0 (powerful and stable server.Eg: Like current 50meg server)

Also he advised me to downgrade to the 50meg to get stable connection. By the time they are doubling the speeds to the customers 100meg issue will be vanish.

that time all servers,cabinets,bla bla will be up to date. 100meg customers will get up to 120meg speed.

after engineer's visit i phoned 100meg tech support team and shared the info with them but the tech team totally denied engineer's statement.they said i should receive 100meg solid connection.

i am confused don't know what to do? since i upgraded 100meg i am restless and depressed.

Regards,

Sen

Docsis 4

Call retention/thinking of leaving they will sort you out 50 Mb

Wow, a "senior engineer" blurting out all that crap? I'm impressed... not.

Erm......... Please someone correct me if I'm wrong but I dont think there's any such thing.

Well, If my comment above is correct (I'm not 100% sure myself but there are a lot here more knowledgeabe than me) then the tech team did right by denying the cobblers the engineer spun you. The next option would probably be to get the fault escalated further up the food chain and make a complaint about the Senior??? Engineer.

Might be worth speaking to any neighbours who are on vm as well to see if they have the same issue as this would point more to the cab/networks side of it and rule out anything on your drop.

Another good starting point would be to post your modem levels etc here for some of the more knowledgeable guys to take a look at.

Like many people in many different jobs/ profession of not really understanding what they are talking about, so can't explain it properly. Also the customer not really able to understand what is being explained to them.

VM's idea of "ready" varies from person to person and area to area.

DOCSIS 3 is the new fast section of the network, your only options are DOCSIS 2 or DOCSIS 3. Believe me, if you were on 2, things would be far worse. 3 is where you should be.

There is no such thing as a "20mb and 50mb connections server". The same DOCSIS 3 bonded channel is used for 10, 20, 30, 50, 100, and (soon) 120mb connections.

Bull. Size of node, not "server" speed is the only relevant thing. The "50Meg server" you're talking about is a 200meg bonded channel. It will soon be upgraded to 400meg. All 30, 50, 60, 100, and 120meg users will still be connected to the same channel. There is no separate server. Or channel.

There is no "server". The same network is used for 50mb and 100mb users. There is no hooking up anyone to anything else. They are improving the capacity of the network, for everyone. 50mb and 100mb will remain on the same network and share the same bandwidth for the forseeable future.

DOCSIS 4 does not exist. Again, there is no such thing as a 50meg server. 50meg users are connected to a 200meg channel. 100meg users are also connected to the exact same 200 meg channel. In some areas, everyone's on a 250 or 300meg channel, with all areas being eventually upgraded to a 400meg channel.

The capacity of the DOCSIS 3 channel is being doubled. All 50meg and 100meg users will stay on the same DOCSIS 3 network. There is no DOCSIS 4 and no "server".

Quote:

Also he advised me to downgrade to the 50meg to get stable connection. By the time they are doubling the speeds to the customers 100meg issue will be vanish.

Also bull. Same network, same connection, same signal, same channel, same speeds. If it's unstable at one speed it'll be unstable at any speed. Again, it's the exact same connection.

What speeds do you get at moment Sen

Andrewcrawford23 · 08-02-2012, 19:39

docsis 4 is only in thoery if that, but i wouldnt expect to see it until 2030!!!!!!! ive know the standard teams that make the specificaiton of docsis are thinking off a new standard which they title docsis 4 but veyr little detail about is known it not even clear if it will us ehte same method as jsut now

to op for a senior engineer he sounds a like right something who jsut told oyu a load of rubbish because eithe rhe couldnt be bothered to fix it or didnt want ot tell oyu the truth

edited as my language wasnt apprioate

totally agree with you on this one

the docsis 4 linkyou pointed to is a proposal from 2008, as theres been nothing since, i presume they didnt bother with it, and why should they, docsis 3 is capable of way over a gigabit as VM themselves have proved with the 1.5gbit trial

I dont think there ever will be a docsis 4, docsis 3 is fast and secure enough, I doubt there will ever be any future docsis standards as everything moves to pure fibre

no docsis 3 is fast enough for now and the foreseable future, but thre will come a time that to provide higher speeds, as 32 channel bonding which i think is what virign are using for 1.5gig is the limit of bonding that docsis 4 would be needed and for virign to go truly fibre would costa lot but to ugprade to docsis 4 if and when it ocmes out would be cheaper and they want that to contunie to compete with bt as the year roll on i dnt think it will bea problem until 2020ish

jsut because the articles are old doesnt mean it doesnt exist it wil be in techincally specifcaiton stage i really dnt know since i dnt know anyone who works in that field, but there is schance it is still getting developed but i think when i read something last year there was talk off moving toa new form tha replace docsis compeltey but again i dnt know it name nor any details

but back on topic the engineer is talking mince

craigj2k12 · 08-02-2012, 21:21

i dont think there is a limit to the number of channels that can be bonded, as long as the modem and line card are capable then i think they could use more

I think its safe to say docsis 4 will never exist, if VM want to provide high speeds in the future they will just use 1024qam and other better docsis 3 technologies

QAM 64? is that correct for 100meg

i am worried to going back to my old 50meg. i dont know weather i will able to get my old solid speed?
i used to get rock solid connection over the last year when i was on 50meg.

my question is
why the conection is unstable after the upgrade? same cable,same cabinet,same area,same computer,same cat6 cable

Andrewcrawford23 · 08-02-2012, 21:50

it possible move to another upstream so because of that means it became unstable unfortnally if oyu downgraded there no arantee if it has changed it would change back

imaxtec · 08-02-2012, 22:50

upgrading from 50meg to 100meg
what are the things changes?
1.IP?
2.Host Name?
3.Line Card?
4.Server?

Suppose if i downgrade 100meg to 50meg how guarantee i will get the old rock solid speed?

if i dont get it? what issue causing and why?
i dont want to pay virgin £30 activation fee all the time when i upgrade
please advice me

cheers
