For some reason, on my home LAN, I have trouble playing Age of Empires. I know, it’s an old game, but I still like to play it. I’m connected at home via a Linksys WRT54G-L. I’ve also connected up a Netgear MR814 used as a hub, but I don’t think that’s the issue. I’m not using dhcp on either of those boxes – I have a separate machine as a dhcp server. Anyways, clicking “Show games” would never work! I thought initially it was some software issue, so I reinstalled Windows and it still didn’t work. I swapped out the WRT54G-L for a switch and then it worked! After some googling, I found that it might be the UPnP. Hopefully, this fixes it. It works now, but then again, it used to work before too. We’ll see.
