Extremely SLOW upload speeds on gig1 package - 0.5mbps

[hortherky]

I’ve recently moved house and the have virgin 1gb internet package. I’ve been testing the speeds daily while plugged in directly into the router via Ethernet and download speeds are only 600-800mbps which is way below the speeds I should be getting.

Upload speeds however have been a disgrace. I’ve been getting regular drops to 500kbps upload speeds which lasts for hours. Even when it isn’t that low I’m only getting a max of 10mbps upload speeds. This is all on wired connection. Please help me fix this asap.

Speed test the service to a Router mode Hub(3/4/5) + your device with the link below.

https://www.samknows.com/realspeed/

Once the test begins click on: Run full test to see all the stats.

The speed at the Hub should reflect your subscription.

Speed at the device depends on its connection type and its ability to draw data at a sustained rate.

thanks for the reply, here are my results. Not sure how my device upload speed is faster than the router but you can see it is terribly low across the board. 

after reading some of the threads on here, I noticed my upload modulation is set at QAM 16 and I am getting frequent T3 time outs which may be causing the issue?

Can someone from virgin please help

[carl_pearce]

It can take several days for a reply on here.

FYI bumping doesn't help.

Hello hotherkey

Sorry to hear of the service issues experienced, we appreciate you taking the time to raise this via the forums.

From checking the connection and equipment, all of the levels and specs are where we would expect them to be. The speeds are averaging 1142mbps download and 30mbps upload speeds, there has been multiple disconnections over the last week but none showing so far today.

Can you let us know if this is still an issue since your post?

So there is an issue with upstream since it should be around 100 - 104Mbps?

[hortherky]

Thanks for the replies @robert_p and @carl_pearce. 

the connection issues seem to have gotten much better since Sunday. Speeds are up to what they should be now and very limited packet loss issues compared to before.
