Network congestion? Poor speeds

[#1]

I'm still in my first few weeks of returning to Plusnet on FTTC, my sync speed is fine (~65Mbps) but my actual throughput today is awful, ranging from about 10 to 15 Mbps according to a few speed tests. Are there some network problems or is this a result of congestion?

Hi @jeffers,
Was the device you ran the BT speedtest on, connected to the router via Ethernet or WiFi?
WiFi can suffer from congestion and inteference.
If the device was connected via WiFi, can you test with an Ethernet connected device?
