Speed

My 150 service consistently runs between 90 and 95.

I have tested it using Ethernet and Wifi and the automated line check says there is no problem and it has reset the line.

I know 80 is the minimum so do I just have to accept it as I thought the full fibre was supposed to give full speed given that the excuse used to be the old copper wires.

@cfcws

My 150 service consistently runs between 90 and 95.

That sounds suspiciously like a faulty ( or cat5 only ) cable, which is limiting the speed to 100Mb.

What does the Hub 2 status screen say for the connection speed ?

Thank you I will check that later.

I may have mixed up my cables.

WAN speed is100 on the status page but the current cable says Cat5E.

Although I am not sure it is the original cable.

Could it be anything else?

Well that's the problem! Now we just need to work out why.

but the current cable says Cat5E.

Does that cable have 8 cores ?

First thing is to try a different cable between the WAN port on the router and the ONT.

You're looking for a WAN speed of 1000Mb on the status page.

It was the cable although I am not sure why as it seemed the same but obviously it wasn't.

Thank you for your help I would not have thought the cable could be the problem.

A faulty cat5e cable can cause the speed to reduce to 100Mb. A Cat5 cable has 4 cores and will operate at 100Mb, a cat5e has 8 cores and is capable of 1000Mb. If there's a bad connector or a break in one core , a cat5e cable will still work but the speed will reduce to the cat5 max of 100Mb.
