Fibre 74 not reaching speed

[#1]

I’ve routinely tested my full fibre speed and it’s not even reaching 50, it’s nowhere near 74. I’ve used the text help option that said there’s no issue with the line.
I’ve been sent upgrade offer but I don’t feel I’m getting any service. Anyone else had the same?

@jenniferedge Full Fibre should give you the advertised speed (or a tiny bit more). What are you using to test, wired or wireless connection?

Can you post the result of speed test from this site, please - https://www.speedtest.net/ - a screen shot would be helpful.

Do your "smart light bulbs" or other IoT devices happen to use 802.11g or 802.11a WiFi to connect to your router ?

as typically a WiFi channel will scale the bandwidth down to the speed of the slowest connected device

and your result of 50Mbps is about what might be expected when the channel has scaled to a 802.11g 54Mb limitation.

Did you ever get a WiFi extender to allow you to split the 2.4Ghz and 5GHz bands to have different SSIDs ?
