Speed issues lately vivid 200

Hi guys, currently on the 200 mb package.

Really struggling with my internet lately. A lot of buffering  on youtube/twitch and slow downloads etc.

Could someone kindly check my power levels and let me know if they are as they should be?

Your signal is far too strong, you should be able to get a technician out to adjust your signals

Re: Speed issues lately vivid 200

Are you able to explain a bit more?

Im unsure as to what you mean by signals being too strong?

Thanks

The recommended levels of power are....  

Downstream: no lower than -6dBmV and no higher than 10dBmV - Close to 0 is optimal.

Upstream: no lower than 31dBmV and no higher than 50dBmV ---   44dBmV to 46dBmV is optimal.

Your downstreams are all above that (upstreams at the low end) - they need bringing into range by a technician's visit.

Think of the data being transferred between VM's CMTS and the Hub as two people having a conversation.
If the two people are speaking normally, then both people would be able to understands the conversation.
What happens when one person starts shouting in the other person's ear?
That person would not be able to understand the other person because the sound is being distorted due to the shouting.

There is a good technical expatiation of power levels here.

Apparently my power levels are within spec according to the woman on the phone. 

"power levels allowed to reach 57 dbmv for downstream"

 

lol.. no idea what to do now

Re: Speed issues lately vivid 200

Call again and hope you get someone who knows what they are talking about.   Try calling “Retentions” on 150 or 0345 454 1111 (or 0800 9528046)  - options 1-1-4-5 "Thinking of leaving" then “technical issues” – (They are open Monday – Friday, 8am - 8pm and on Saturday from 8am - 6pm. – [08.01 is best!]) you have a better chance of getting a UK call centre (it could still be a 30’+ wait though) who will be more understanding and helpful.  Tell them the issue and the discussion on this forum and they should sort you out - if they re unhelpful just tell them you will be calling back to cancel.

Absolute rubbish, typical of the offshore call center. and VM are closing Swansea down, where they know what they are talking about. and do not make basic fundamental mistakes like that.

57dBmv is the maximum upstream transmit power level for a single unbonded upstream channel.

You could try braving the call center again, or you could wait until a VM Forum Team member who knows the difference between upstream and downstream to pick up the thread.
