Slow broadband and intermittent connection

Tuning in

Hi,

The past week I have been suffering very badly with slow broadband and an intermittent unreliable connection. I use a mix of wired and wireless connection types.

I have tried calling support direct but have had little luck.

I have posted my logs below, hopefully I've done this correctly.

Any help would be greatly appreciated.

Downstream power levels are too high and upstream should be 64 QAM.

You need a technician’s visit to rectify, try calling customer services again, 08:00 is the best time. A VM staff member will get to your post, but it may take a day of two.

Thank you very much for taking a look at this! I will call VM this morning and see if they can send an engineer out to me and reference I have received advice on this forum 🙂

Thanks again!

Update after my call with VM support:

1. It seems that a "switch" was switched off(?) and has now been switched on, this allegedly will yield better results - faster speeds and more stable connection. I am a little skeptical as it sounds too good to be true, and surprised this "switch" has never been mentioned before the past 3/4 times I've called VM support. In any case I'll keep my fingers crossed.

2. I was told that there is a problem in my area despite the VM Status Report consistenly showing "no problems in my area" - this is preventing the support team from booking an engineer despite having good grounds to book one based on the information I recieved about my power levels being off. Can anyone confirm if I am able to get an engineer sent out whilst there is a percieved problem in my area? I'm worried that even if there is a problem in my area, how can Ibe sure that fixing the area problem will resolve my issue when the rootcause is unknown.

Any advice or experience would be appreciated! 🙂

Sounds like typical CS Bullcrap to get you off the phone!

Can someone flag this for VM staff as the phone advice has been shocking!

The web page status report only covers 100’s of users, it’s best to check with Area faults on  0800 561 0061 or if you have a VM landline 150

Another update, earlier today I called 0800 561 0061 whilst my connection was down and was told there were no problems in my area. I called again now, 10PM UK Time, and there a still "no issues in my area" - but needless to say my connectivity remains bad and I'm unable to get an sent out engineer out.

Is anyone able to assist and get an engineer sent to my address so they can check what is going on and fix?

Alternatively, would anyone know if purchasing another Router and running my Virgin Hub in Modem mode would have any results?

Thanks again for the advice so far guys!

Could anyone advise? I've called again today, same situation - no report of a problem in my area but really bad connection quality and Customer Service are unable to send an engineer out. Really stuck on what to do...
