Upload Modulation gone to pot

Hi

Just had a tech visit to move my hub from upstairs to downstairs, job was completed but now my upload modulation is 32 qam across the board and power levels have all dropped (they were all around 46)

The tech was in a bit of a rush to say the least and did not check anything. I have reset & rebooted several times but issue still remains

Re: Upload Modulation gone to pot

Power levels are fine 32qam is not "normal" so can you reset the Hub again as below and see if they reconnect at 64
__________________________________________________________________________

Note that a pinhole reset on a Hub3/4 can be a bit problematic - so do it (again) EXACTLY this way (not as the VM website says!).
Firstly, make sure the Hub's sticker/card with the two passwords on it is still there and legible If not – DON’T DO IT !

With the Hub switched "on", disconnect any ethernet connections (leave the co-ax connected) and then push in the “reset pin” with the end of a paperclip/thin nail/SIM tray “tool” or similar (bigger items like ball point pen ends may not press it in far enough) until you feel it at the “stop point” and hold it there firmly for a "timed" minimum of 60 seconds do NOT manually restart the Hub at any time. Leave it 10' or so to stabilise and then your passwords/passphrase for both the Hub settings and the Wifi networks will revert to the two printed on the Hub sticker on its base/side/card. Make sure you use the wifi one for devices connecting to the wifi and the settings/admin one to access the Hub

See if that sorts it.

Re: Upload Modulation gone to pot

OK.

On occasion VM can configure your network to run at a lower qam - but a VM person would need to look at that and comment.

So........ What issues are you experiencing on the connection?

Can you post up the rest of the Hub's data - the 2 tables from the Downstream, 2 from the Upstream, & the Network Logs page.

Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - or - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again. If character limits are “exceeded” - just do two posts

Re: Upload Modulation gone to pot

As to issues, speeds seem a bit erratic now with occasional buffering streaming.

Everything seemed ok before the hub move

Re: Upload Modulation gone to pot

Seems I have been having some issues for some time wrt packet loss (albeit small)

https://www.thinkbroadband.com/broadband/monitoring/quality/share/aacc90f1c66eb9d95a1ac9e88b5e41be157fd94a

 Just lately service has been pants with multiple disconnects etc which admittedly have been due to a network issue, but apparently that was sorted only to be replaced by something else !
