Cannot play with LAN on all multiplayer video games with wireless internet connection

[Kevin Fox]

Hello, so i play LAN games with my friend(s) and my brother alot, usually i play with my wi-fi connection because i didn't have a wired LAN cable (i used to, but it broke), we play lots of games, and they usually have no problems, but now, this problem happened.

Recently i wanted to play Call of Duty: World at War in co-op mode with LAN, but then now i got the problem where the LAN server does not appear in the server list, note that it does not matter who the server host is, the server will never appear on the server list. So i tried to play other games that support LAN, and the server still does not appear. All games that support LAN multiplayer does not work with the wi-fi connection/WLAN.

P.S I have a workaround that can make me play games with LAN with my brother and my friends, that i have to use my phone's personal hotspot, the server appears with it, but the problem is, my phone runs out of battery fast, with the hotspot mode turned on it won't last for 30 minutes, and the computers always have a weak connection signal, so the ping is really high.

Any solution would be really helpful. Thanks in advance.

EDIT: Firewall is turned off in all computers, and they are connected in the same network.

Check your router wireless settings. Some of them, as a security measure will separate the wired and wireless networks. It's called wireless isolation on my router. Also be sure that the all the computers are on the same network.

All computers are in the same network, and what is that Wireless Isolation thing and what do i do with it?

Wireless isolation separates the wired and wireless devices. Basically it puts all the wireless devices in a different network. Find it in your router settings and disable it.
