I don't know if this was related, but earlier today my personal internet dropped to 1mbps down for at least 30 minutes. Also had 40% packet loss using the cloudflare speed test on a wired connection. East coast, USA.
I’ve come to love powerline adapters when expanding Wi-Fi coverage just in case you haven’t looked into them. Speeds of the latest adapters are up to 2.4Gbps!
