Getting half the download speeds on Gig1 Fibre

[FilipeB]

Since the 30th of September, internet has been flaky. Speed tests since then have shown my download is around 500Mbps instead of the expected 1000Mbps. Upload speed was also being very low at 35Mbps but after a reboot it went back to the expected 100Mbps. Stability has also not been great. Trying to run the checker on virgin media website returns an error. It says there are no issues for the postcode itself.

First try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues and fix estimates, down to street cab/ postcode level.

See if anything is being reported there

If not do this...

Post up your Hub/network connection details and someone will check to see if there is a problem there.  In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. No need to log in - just click on the “Router Status” icon/text at bottom-middle (Hub3/4/5) or top/right (SH’s) - of the Login page.
Then… Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - 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

Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. 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 then click OK

Thanks for the info jbrennand.

It seems like the speeds have self-corrected themselves.

In regards to setting up the quality monitor, I've already done that, in fact I posted a graph from thinkbroadband itself in the first post. It still doesn't look very stable there. For comparison see this graph from the 24th of September

I guess I'll wait until tomorrow to see if it is more stable...

Given that the speeds fixed themselves, is there still a need for the downstream & upstream data?

[FilipeB]

Definitely doesn't look like it's getting any better... 😩

[FilipeB]

This morning quality looks better

but speeds are back down to half.... 😩

This is the upstream/downstream logs

Speeds are getting even worse. Account checker says there's no problems with my account/hub 😩

What can I do here?

[legacy1]

Do a steam download and see what speed you get

[FilipeB]

The speeds just keep getting worse now

Tried restarting the router and it stays the same

[FilipeB]

So how can I get an engineer to come look at this attrocious performance?
