Router is blocking many of my games that require internet. (Steam, Pokemon online)?

My own games are not working and also I’m fairly sure it’s got related to my laptop because currently I introduced it for the library and also somehow the games (steam, pokemon online) been effective, and when i brought it back it still doesn’t work.On pokemon on the net, the hosting space won’t display and steam will not likely open.
If anybody knows simple solution, I was dying to uncover.Thanks ahead!

I would verify if your router sustains UPnP (Universal PlugNPlay).

Enable UPnP in your router, next restart the item.
