I hear this thing about reliability, but how can it be more reliable than reliable? If I was losing sync all the time or going on a go slow then I would think differently.

Believe it or not but they don't use data specific to your specific line when sending out mail to everyone who now has FTTP available.

The increased reliability quoted isn't made up, or propaganda. It's a direct compassion between copper broadband and full fibre broadband using verifiable figures.

The fact your FTTC is stable is lucky for you and you alone. It doesn't make FTTP less reliable for everyone else.

On the whole FTTP broadband is much more reliable than FTTC broadband.

@OP. What do the TBB speed test Analysis results show?

Given the slow single connection results and the problems with variable rate streams it suggests some significant short term changes in speed possibly caused by packet delays / order.

Regarding your streaming problems, I'd suspect that CDNs use algorithms that are quite conservative in a sense that they will tend to operate at lower rates if the connection shows even short term limits.
It could be that these algorithms are more tuned for mobile use than they were.

The only way to get a proper result is to use Fast.com.

Should've told us you're a comedian...🙈😂

[a GbE connection above for the avoidance of doubt]

If you :
A) uninstall any “security software”
B) use a private browsing window
C) compare with others to get an average

Then fast.com along with all browser tests are worth using together.

It can work reliably but not on all browsers or setups. Same as any of the others that rely on browsers sadly.

Apparently my phone can manage 1.0Gbps on WiFi....

Somehow I think.....not.

And thats the rub of all speedtesters imo.

Although i have just used the Speedtest.net app and compared with Fast, and both were quite close in terms of results.

If I use the TBB speedtest i get around 2-400Mbps, and thats on most browsers.

Agreed, something is up, it would be interesting to investigate. I tend to see my 250 Mbps WAN speed quite reliably, and at work we get around 800/900 from our shared 1Gbps leased line circuit (but quite a lot of users). On mobile of course the CPU sleeps a lot. The speedtest.net "app" is probably a bit better than a web page. And on iOS its only worth using Safari as the other browsers are forced to use WebKit, its unclear if they get the faster Javascript implementation. (viz, EU complaint...).

Fast.com always overestimates my line. That goes for Chrome/Firefox on Windows and my Android phone.

Just run this test wireless on my phone.

570Mb/s is not bad for the 550/75 Openreach product.
