Arcadyan KVD21 Gateway preventing my PS5 from connecting through ethernet
Recently just got a ethernet cord from a friend and expected better speeds than 7Mbps (which I have been having) so I can play Helldiviers 2 with my said friend and not lag or get kicked due to "connectivity issues" every 10 mins. Instead Igot an issue with the ethernet,I connected an ethernet cord to my arcadyan KVD21 gateway then to my PS5 went to establish the connection on my PS5 it worked for 5-10 minutes, then it wouldn't connect with my PS5 saying that the router might be preventingthe ethernet connection, and to make sure I can connect regularly (which I can) by testing the connection using my computer or mobile device. What should I do? Am I able to change from IPV6 to IPV4 so I can connect my PS5 through a LAN cable? Does the arcadyan KVD21 gateway not support ethernet connection to PS5? Am I gonna have to switch Internet Providers?
