These are ARP broadcast requests sent by the machine with MAC address Cybertan_66:22:d1 and likely IP 192.168.88.246 looking for the machine with the IP address 192.168.88.1. As the target IP ends in .1 I would assume that's your router's local IP and the the requesting IP (.88) is your machine looking for the gateway.
I would guess that your router has failed in some way on the local side. Are there any logs in the router or status page that you can inspect?
