I've got a 2degrees ultimate fibre plan that I have traditionally used with my Unifi USG router, I've recently moved back from a 3 month period out of the house and during that time the connection was moved with us but I used my old fritzbox 7390 instead as I couldn't move my entire network with me.  Previously I had the USG running IPS/DPI and accepted the lower performance as I was hosting some external web stuff and wanted the security etc. for the open ports.  These where migrated to a cloud provider prior to the temp move so turned these off to get full speed as the USG does support 1Gbe internet connections.

Now we're back in, the USG was only giving me ~100/128 which suggested that DPI/IPS was still turned on despite the settings so I thought I would try with the Fritzbox again, but that is capping out at ~300/400, well below the 900 or so that the plan should provide.

Now I know that speedtest.net etc. isn't that reliable and it varied substantially amongst the different providers but Steam was only pulling at ~280mbps and that can run fast normally and an MS server 2019 ISO from the MS Website was ~ 260mbps too.  Before I log something with 2degrees I wanted to see if there was a reliable way to check the connections maximum speed.

For interest network topology currently is:

ONT > Fritzbox 7390 > Unifi Flex Mini > Unifi Switch 24 (Gen 1) > Unifi Switch 24 POE (Gen 2) > Unifi NanoHD

Previously it was:

ONT > Unifi USG > Unifi Flex Mini > Unifi Switch 24 (Gen 1) > Unifi Switch 24 POE (Gen 2) > Unifi NanoHD

Switching from the USG to the fritzbox has increased the download speed by ~200mbps but I cannot seem to reach the full 950mpbs that hte plan is supposed to achieve.  The entire house is wired (as you can imagine from the amount of switches!) so there is no wireless network in play when it comes to testing.

Any comments/thoughts?

Thanks,

Chris
