Every 5 minutes exactly I get 20 seconds of TCP Previous segment not captured

edit

This happens whether I'm connected to my home network or to a mobile hotspot, and it only happens on my computer. I've measured it numerous times and it's always every 5 minutes with 20 seconds of this problem. Wireshark gets flooded with TCP "Previous statement not captured", "Dup ACK", "Retransmission", and "Out-of-order" and I get lots of packet loss and increased ping times (from 20-30ms to 100-200ms). I'm on Linux Mint 22.3 and I've tried nethogs and iftop but neither have shown anything out of the ordinary.
