I don't know why ISPs don't deploy some form of bandwidth testing facility (e.g. iPerf3) to their routers (possibly even locked down to only accept requests from the ISP) which can be ran remotely by support desk staff.

Would allow them to quickly rule out the wider network if the issue is internal. I would hope no ISP is silly enough to supply a 330Mbps G.Fast connection with only 'Fast Ethernet' (100Mbps).

That first one is me - but still experimenting with cables and PC settings so not really representative yet.

Have also been experimenting with moving the hub nearer the PC. Long lead between hub and modem, shorter lead to PC rather than the other way round.

Would it be possible, when you find a spare 10min!, to put up a short guide on what people need to check on their 'customer' equipment when getting a G-Fast connection that doesn't meet their expectations. We can then refer people to this or they can find it themselves

Thanks

Suggestions so far are

Network Card settings
Quality of Ethernet cables ( Any recommendations on standards).
Ensuring the use of a Gb port ( not 100Mb port)

(I am assuming that the ISP supplied routers are suitable)

Some devices may have both Ge and 100Mb ports.

I have also been shocked by how many new laptops and notebooks are only fitted with an FE ( 100Mb max) network card.

I know one ISP that provided trial customers with their branded router that only had 100Mbps ports. I'm not going to say who, but there is a lot of equipment out there not capable of running above 100Mbps.

I suspect that firewalls built into routers are often a bottleneck, even if the interfaces connect at gigabit speeds.

There's a lot of cheap Cat 5e ethernet cables on eBay etc that all claim to support GigE, but more often than not they are made from copper-coated Aluminium (CCA), and struggle to get more than 100mbps especially as the cable length increases.

I always look for reputable suppliers that guarantee the cable is 100% copper.

In reply to a post by MrSaffron:

This is one of their speed tests I believe http://tbb.st/1498650610209466055

Others are pushing single thread to what you'd more expect http://tbb.st/1496272629115041655 (that is a FTTP location though)

Apologies for the delay. Day job got in the way!

Have now got two Cat6 cables to test and they have increased the download speed.

Using the BTW checker I consistently get between 300 and 310. Same with a couple of others. The one on this site is giving me an average of 200. All four show the upload speed in the range of 30 - and I cannot seem to better that.

I have switched to the Business 5 Hub simply because it allows it to be pinged from the net rather than setting up a DMZ with the home hub. This allows me to use the quality monitor this site. No change in speed results.

A couple of questions...

When I download the 1GB test file from this site it suggests it should take 75 seconds at 120Mbps. Assuming I am getting a minimum of 200Mbps (depending which tester you use) I seem to get the file in around 105 secs. Any suggestions where I should look to improve that?

Secondly - is there a link which would produce an image of my average test results - I can get a link to produce a particular test but would like an average one. Or is it there and I have missed it?
