I have a 2Gbps internet with Quic, but it has gone down to around 900Mbps in the past few months.

This is a screenshot of a speed test made in November from my mobile phone:

This is a speed test from the router (which is connected to the ONT) directly to the internet today:

Nothing changed on my end - no firmware updates nor new features enabled (i.e. firewall, QoS). So I need Quic's help to troubleshoot this better, but they haven't replied to my emails.

I have 2x TP-Link BE85. ONT is connected directly to one of them via a 2.5G Ethernet port.

What I've done so far:

• rebooted routers, ONT
• speed test directly from the Router

Please, if anyone from Quic here can help, that would be much appreciated. Thanks!
