Problem with local network.

[Oliver2604]

Hello, I have a problem with the Monster Hunter Freedom Unite and it is the following, when I try to play in a local network with my brother, when he joins my room it does not appear (but on his device I do appear to him sometimes, but my brother does not appear to me), and this happened from one day to the next, because before we could play without problems, I have uninstalled the emulator, I have reconfigured it and nothing happens, I cannot play on a local network and it is a problem that It affects me if I try to play in global multiplayer via the Hunsterverse, the same thing keeps happening to me, no one appears in the room. I don't know what to do, since before we could play without problems and now we can't play. It's frustrating.
