I understand the maximum. It should be 10Mbps actually, but I think Vodafone say 9 as there is some sort of Ofcom rule saying they can't quote speeds above what they provide.
Uh, its a bit complicated.
Given the max is 40, well 36 is quoted, download and I get near or even above this, I don't understand why I only get a third of the upload (9 or 10Mbps).
There are two products from Openreach that the ISP can purchase, the 40/10 service or the 80/20 service. They are both "up-to" these speeds, depending on the quality of the wire in the ground from the green box to your home, and the quality of the wiring in your home (number of extensions, etc).
The 40/10 service is the speed the
router is connected to the green box at, but there are technical overheads (how computers work) that reduce the data
throughput that you can get.The ASA and Ofcom agreed the current limits on ISP marketing.
With a laptop or desktop connected by Ethernet to a router on a 40/10 service,
assuming a good and short copper line then the maximum speeds you can get is 36 download and 9 upload in megabits per second (Mbps)
Many copper lines in the street are
not good quality and as you have a very expensive box at the Openreach end, and a £50 router at the home end, often the download speed is close to the quoted, but the upload speed is less good. This is why people want "full fibre" or "cable" instead of copper wires in the street, as there is less variability.
Edit - you are on an FTTP service, so you get the 40/10 speeds at ANY distance. The overheads of the TCP/IP packets and the PPPoE encapsulation is why the usable throughput of 36/9 is permitted to be advertised.
It's obviously not an iPad limitation given the quoted 144Mbps, even if we allow for all sorts of veriables.
This 144 is not guaranteed, if you don't live in the middle of the country there are other radio transmissions around you (coming through your walls) that can interfere with the WiFi speeds. This is why people upgrade WiFi technologies to get more total capacity so that with interference they get more usable throughput.
In your case, without an Ethernet adaptor for your iPad, or a laptop/desktop connected by Ethernet, you
cannot reliably test this.
For example at home I have Virgin Media's service which is 250 down and 20 up. On my 3 year old desktop PC I can go to speedtest.net in my Firefox web browser and see speeds of 240 download and 19 upload. This is good. On a 5 year old Android phone connected by WiFi standing only 2 metres from my router I can only get 180 download and 6 upload.
Can you borrow a laptop or something with an Ethernet connection?
Which iPad do you have?
