I've just had BT FTTP 900/110 installed to replace my VM connection. Speeds with the BT Hub are OK - a bit unstable and never stay at the top end. I'm putting this down to it being 24 hours since installation and hopefully it will improve soon.

My main issue though is I want to use my Meraki MX router instead of the BT Hub. I've already tried swapping the BT Hub for the Meraki but my speeds drop like a stone. They go right down to 350 down and 0.35 (yes, 0.35!) up.

I've even connected my laptop direct to the ONT and I get the same speeds - 350/0.35 - which leads me to think it's not the Meraki causing the issue.

What do you think? Any ideas?

Cheers
 
How strange, I've been doing all my speed tests on speedtest.net, but I've just tried Fast.com, Google's speed test and broadbandspeedchecker.co.uk, all of which give me waaayyy better results - like full speed up and down. So it appears the issue is with Speedtest, but why? How?

What MX model is it? Meraki boxes are hard capped at the speeds they quote you on the spec sheet.

It's an MX105 so well capable of 900/110.

Update: I've just downloaded a server .iso from Microsoft and I was getting 503Mbps down. I've also just downloaded another .iso from a hosted server and I'm getting 750Mbps. As for upload, I'm sending another Windows .iso to a hosted server and getting 109Mbps up.

So up to now, my issue is with Speedtest. What do you think?

What results do you get from https://speedsmart.net?

I just tried Speedsmart - I'm getting between 600 and 800Mbps down depending on what server I choose, and 112Mbps up regardless of server.

It's for reasons like this that I use a private iperf server, I can be as sure as is reasonably possible that the result I'm getting is accurate as the iperf server is sitting on a 10Gbps internet connection.

I've just done an iperf test on to an Azure server I have. These were the results...

Code: 
PS C:\temp\iperf> ./iperf3.exe -c XX.XXX.XXX.XXX -p 5201 -ub 1G

Connecting to host XX.XXX.XXX.XXX, port 5201
[  4] local XX.XXX.XXX.XXX port 60258 connected to XX.XXX.XXX.XXX port 5201

Just tried Speedtest again and getting awful results. Fast.com are giving me really good ones.
