I have the 1000/100 internet connection and the internet connection speed (upload) has been markedly slower since around the Christmas period, at least as my son has informed me.
The UPC router is set in “modem” mode (system is running through a Ubiquiti Dream Machine Pro router).
The download speed seems to be working perfectly fine, however the upload speed reaches only around 25 Mbit/s.
Looking at the UPC router, only one DOCSIS 3.0 channel is detected for the upstream, whereas for downstream, I see 24 x DOCSIS 3.0 channels and 1 x DOCSIS 3.1 channel.
I have measured the speed on the CNLAB utility over the course of the last days, my userID is 5747363427618557.
Can you please check and advise if something I need to check at the house (i.e. coax connectors), or if some issue with the connection can be seen from your side.
