Internet Speed Slowed A LOT a Week Ago

My internet has recently become awfully slow and frustrating.

Nothing in my physical environment has changed. I have AT&T fiber and use an Ethernet connection from my computer to my fairly new modem/router.

On speed test bandwidth, or latency.

Latency
Some things seem to load alright, but many other things are dial-up level speed. No significant changes in either hardware or software (except that I run Mint update every few days), and it happened almost overnight a while back, but has not recovered.

The DNS is probably bogged. Change dns and see if things load quicker.

Knowing fohat who goes to those democrat luigi radical left websites,  probably want to use 9.9.9.9

If nothing changed physically, I’d honestly start by checking whether the slowdown is actually coming from the AT&T side or from the router itself. A week ago sounds more like either: a bad firmware update on the modem/router the router negotiating the Ethernet link at the wrong speed or some issue on the ISP side I’d first reboot both the ONT/modem and router completely, then run a speed test directly over Ethernet again. Also worth checking if the Ethernet link somehow dropped to 100 Mbps instead of 1 Gbps. I’ve seen that happen from a bad cable or even after a router update.
