AL5: upload speed back in the dak ages

Been back for a week and noticed that the upload speed is back where it was at the begin of the lockdown.

I should have 10MB upload, I only get 1MB.

Things were better at the begin of August, but now I believe it had nothing to do with network improvements: people were on holiday.

Now they are back and upload speed at peak time is poor again (download is stable at > 100MB).

What does VM say about this? And more importantly, what is VM going to DO about it?

Original problem discussed here: https://community.virginmedia.com/t5/Speed/AL5-no-light-at-the-end-of-the-tunnel/td-p/4280173

Re: AL5: upload speed back in the dak ages

How are you connecting your device, Wi-Fi or ethernet cable ?

It can be difficult diagnosing problems without some basic information.

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting the area. Be aware that it isn't a manned line.

Go round all the accessible co-ax connections and ensure that they are finger tight.

If everything above is OK we need do some troubleshooting; to start with …

 

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a link to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

 

Then

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream and Network Log tabs onto here, if you get a yellow warning click the Post button again.

A Guru will be along soon to decipher the info.

What does VM say about this? And more importantly, what is VM going to DO about it?

Given how long this has been rumbling on for, I would have thought that the question is what YOU going to do about it?  In your shoes I'd have jumped the VM ship months ago.  Just make sure that if you are planning to take your business elsewhere, you check out customer feedback on any proposed new ISP on sites like Trustpilot and ISPReview before you commit.  There's some excellent smaller ISPs, and ISPReview will show you the shortlist.

Re: AL5: upload speed back in the dak ages

Same issue for me still in AL5 as well.  5 engineers have been to visit over the last 6 months but it's an area issue that I am trying to get escalated.

You are definitely right.

I almost got the BT contract started, then realised I first need to put an aerial on the roof as they do not provide freeview on their box, then went on holiday.

Pure laziness on my side.

Re: AL5: upload speed back in the dak ages

How I measure speed makes absolutely no difference. The PC is connected directly to the router, but on a WiFi tablet I get exactly the same reading.

Since the upload speed is around 1MB, the bottleneck is not the WiFi (which makes a difference for download speed).

https://www.thinkbroadband.com/broadband/monitoring/quality/share/3c0c813e2d323dfdb3733c65353557a689... 

The regular spikes are probably due to the speed report job I run every 15 minutes. (which I stopped yesterday evening).

The upload speed issues are so regular between 9 AM and 7 PM that one could even thing they are intentionally throttling it.

Someone came recently to fix the power levels and guess what, no difference.

I think the problems are so massive than none of these minor tweaks make any difference at all.
