Wifi speed on old iPads

Found this https://support.apple.com/en-gb/guide/deployment/dep...

Does this mean 144Mbps is the only limit on Wifi speed?

Some are suggesting that an UL speed of 3Mbps on a 40/10 FTTP connection is down to the devices. How would this work when the linit looks to be over 45 times that?

Very briefly - 144Mbps is a headline marketing figure - only achievable in a perfect environment.

Since wi-fi relies on radio and radio is a shared medium more devices means less bandwidth available per device.

Add in interference from neighbours wi-fi, bluetooth, microwave ovens, passing buses with wi-fi on board.

Factor in the fact that wi-fi signals are attenuated by walls, furniture, bodies, etc.

Factor in that you can have reflections from all sorts of objects.

Good rule of thumb is half the theoretical “headline rate” in actual throughput and you’re doing quite well.

OK so not the advertised figure: I get that but only getting 1/45th is pretty dire, no?

So 1/45th inducates something is wrong?

If you are talking about uploads to the Internet, the maximum for your connection is 10Mbps. So, however you are connected to your router, that is the absolute maximum you could get; in practice you will never achieve that. You are getting about 1/3 of that speed, not 1/45.

If you Google "slow wifi iPad" you will find a number of suggestions to improve the speed. But, in my experience, old iPads are notoriously slow and inefficient nowadays. It's almost as if they have built-in obsolescence.

I'm on a 40/10 FTTP connection, so the 10 refers to the upload, not the download. Is the quoted 144 for downloads? If so what is the upload?

Let's say it is 30. So 3 is only a tenth of what is possible, no?

I understand old technology is going to be slower than modern, but I am taking advertised figures, do these change as the hardware ages?

I read UL speed to mean "upload speed".

If you are talking about download speed then yo are getting about 1/13 of the theoretical maximum, not 1/45.

You read correctly"

Take your iPad and test it on another connection, ideally faster than your own domestic connection snd it should pinpoint whether it’s your iPad or broadband that’s at the limit / issue.
