Long story short if I wire my PC to the dish in my mesh I get 350/400mb (I'm on a 900mb connection, another long story but not paying for it so why not have as fast as possible).

That dish is in the office so i thought the smart thing to do was wire it into a switch and then wire into my PC and the 2 work laptops to all get at that 400mb.

When I wire into a gigabit switch whatever I plug in gets 100mb/just under.

It's definitely a gigabit switch, I'm using 5e/6 cables.

Is this a case of some gigabit switches being better than others? Or am I missing something?
 
Dish?

Getting a 100Mbit connection is usually a wiring issue (assuming both devices are Gigabit capable).

100Mbit only requires two of the pairs. Gigabit requires all four.

Some cables do only have two pairs in them (usually cables bundled with devices).
 
Sorry, I mean bt whole home dish.

They have an ethernet port on the back, if I connect that to a pc or laptop it gets roughly 400mb. If I connect it to this switch and then to the the same machine it gets 100ish

Tried with various cables for what it's worth, cat6 and cat 5e
 
The LEDs on the switch should tell you what speed it's connecting at.

If you have PC <-> Switch <-> Wireless Disc what are the indicated links speeds?
 
The machines are all suggesting 1gbps into the network but only managing suspiciously close to 100mbps down and up on speedtest.

Then when I remove the switch and wire directly to the disc they jump to approx 400mbps so I assume the switch is the issue?

Its a brand new but cheap dlink gigabit 8 port switch.
 
Yeah that's not a bad suggestion.

Laptop directly into the router is 900mbps, laptop directly into the mesh is 400mbps, mesh into the switch into the laptop is 100mbps.

Just in case I have a bundle of cat6 cables and a better switch coming tomorrow.
 
Just to be clear, are you connected via Ethernet to the BT disc/switch, that is meshing (wirelessly) with your router? You're not plugged directly into the router are you?

Your explanation seems to imply this... If so that will explain the bandwidth dropping to ~400Mb. The fact using a switch makes it drop to 100Mb implies either you don't have a gigabit switch, or the port is somehow running in 100Mb, or a bad cable.

You will not get the full 900Mb without being wired direct to the router, or running a Cat6 cable direct from the router to where you want it.
 
OP is trying to find out why he gets 400Mbit from the remote disc if a single device is connected, but only 100Mbit if the device is connected to the same disc via a Gigabit switch.
 
No I get I won't get 900mb.

However, trying again today I got 350mb and I did mess with the cables a bit, I think I might have had a cat 5e cable (marked as such) which was just a cat 5...
 
There's not much difference between Cat5 and Cat5e. At the distances you'd be dealing with it isn't going to matter.

I'd assume a dodgy/faulty cable or one that's only partially wired. Look carefully and make sure all eight wires are terminated in the plugs. There are cables out there that would have been supplied with equipment only capable of 100Mbit where they saved a few pennies by only having two pairs instead of four.
