Hello All
I have had the vodafone Gigafast 900mb service in Milton Keynes now for about 3 months and am getting only 500-600mb download speed on my PCs. My router is detecting the speed at 1000mb.
I have had a vodafone tech out but they have said that it is a known windows 10 issue.
I have updated all of the LAN drivers on all 3 of my PCs and replaced all of the network cables with Cat6, I have even upgraded the rubbish vodafone router with a Top of the Line Netgear XR500 but am still getting the slow speeds.
On the plus side my upload is around 1600mb
Has anyone else had this issue or any ideas on how to rectify this please.
I really dont need that much speed but as im paying for it it would be nice to get it working
Thanks Marc
Hi Marc
What are you using to determine those speeds? Speedtest is renowned for not being accurate! How about looking at running iperf from your machine to a public iperf server. What do the results for that look like?
Hey @jasperb182, our Gigafast broadband has a dedicated team that will be able to help. You can contact the Gigafast support team buy caling 191, free from a Vodafone mobile. Also you can call 03333 040 191 from other UK landlines or mobiles (standard call charges apply)

its telling me that im getting 250mb lol
the prompt im using is iperf3 -c speedtest.wtnet.de
Download the binaries (win 10, 64bit, for example - https://iperf.fr/iperf-download.php#windows)
unzip, open a command prompt and switch to where ever you unzipped the file, ie. C:\Users\matth\Desktop\iperf-3.1.3-win64
the run the command:
iperf3.exe -c iperf.volia.net (you can select alternative servers if any are busy from the list here: https://iperf.fr/iperf-servers.php)
Wait for the results:
C:\Users\matth\Desktop\iperf-3.1.3-win64>iperf3.exe -c iperf.eenet.ee

iperf Done.
And you're paying for the 100mb gigafast service? Doesn't seem right does it!
im paying for the 900mb service.
My router is connecting at 1gig but a speed test is only getting me 650mb ish and someone surgested tryting iperf.
Hey @jasperb182 did you contact our dedicated Gigafast team about this at all?
They've got the tools to test your service to see what's causing the bottleneck with your speed.

Through Speeds for me on 100 Mb line (non issues )
Download around 30Mbp/s
Upload 110 Mbp/s
Regular line drops and server disconnections when gaming. It is not line related but Exchange oversubscribed.
Generally I feel cheated. First 3-4 months it was 100/100
Hi. Cheated sounds a bit strong! It's still much better service and probably cheaper than what you were paying before?! Take care how you measure it as well. SpeedTest and the like aren'e always the most accurate. Are you on the Vodafone supplied router? I've not had any drops since a 1 day outage a few months ago (see separate post). I'd be surprised too if the Exchange was oversubscribed for FTTP. That was a common problem for FTTC connections but the numbers for FTTP in MK are a lot lower at the current time.
Could someone on VodaFone's GigaSlow service post a couple of traceroutes.

It would be interestsing to see if they route traffic over the same shonky network that the FTTC users are forced to use.
All standard, all working . I'm IT engineer. What follows from your reply - here is a traffic management in place. I like to watch IP HD TV.
In comparison with EE or BT broadband VF is cheaper indeed. But if I'm limited to 34 Mbps then it is more expensive than EE. Well ping now is 5ms against 9ms I had before.
Here are a few of those. Wireless onto the Gigafast100 service

High ping and delays on Vodafone exchange hub. No problems before and after. It just confirming what I said. VF infrastructure slowing down internet traffic
Have you contacted our Gigafast team about this yet @Mozambezi?
We're not traffic shaping, and it's very unlikely that this is down to congestion. If you’re only having the issue on certain sites, or servers then there could be an problem further back on the network. Our Gigafast and 3rd lines teams will be able to help, they may need to pathpings and tracert's from you, but if we can locate where the bottleneck is occurring, we can get it sorted.

Hi,
I have been following a few of the topics in the forums with interest, and I thought i would post my experiences with Gigafast so far.
I chose the Gigafast 900/900 (due to the £9 discount as an existing vodafone customer) service which was installed roughly a month ago. Like many I have been having some streaming issues via Netflix / Prime video. One time Amazon prime Video came up with a warning "I do not have enough bandwidth to play this video" when trying to stream a 1080p link.
I use an NVIDIA Shield connected via Gigabit Ethernet within a few feet of the vodafone router.
I have been getting erratic speed tests results from speedtest.net / fast.com / think broadband some as low 30mbps down. I get similar results via two different computers that are also connected via gigabit Ethernet.
I have been in contact with vodafone support a few times for what seemed like an eternity trying to get through. I have been asked to email speed tests / traceroutes as requested for by the Level 3 support to look through. See what happens !!
Here is a traceroute from netflix.com - first is via vodafone - second is via a VPN.
