So, me and my brother are trying to connect to each other using LAN worlds. At first it works fine, but after about a minute he starts to stand completely still on my screen as if he was lagging, but on his screen he's moving completely normally. Then it'll abruptly log him out of the server. After that, trying to rejoin gives the message "connection timed out: no further information:" is it something with our wifi/computers? We both have Java edition and Windows 10 computers, and we're right next to each other when we try. We even tried using direct connect.
