LAN major lag and cannot see friend sever

Hi guys, i hope that you can help me with this problem. Me and my 3 others friends just recently brought don't starve and i am the only one who can host the sever because if others hosting it, everyone simply cannot see it. Even then, my friends still cannot enjoy the game because my sever was too lag (our internet here is kinda potato). So we try switching to LAN, with cables but the lags continue, and we still cannot see each others sever (i did turn the option to local network). My laptop specs is:
I7 5500u
GTX 950M
8GB
Hope you guys can help us, we really enjoy the game but the lag kills all the fun. Sorry for my english
