My current setup, Wave 7 Optics LMG-441E Gateway, going into a Linksys going into a WRT54G Router, with a Cisco SE1500 Switch. I'm running a Minecraft server with a wired connection to the switch, wired to the router, wired to the gateway.
I'm not well versed in networking, and I've noticed we're experiencing some latency issues on the server, and I'm under the impression that upgrading my LAN won't help me any. I have a 15MBps down/ 5MBps up connection. I wish it was better, but I'm not fortunate enough to live in a place with a good broadband connection.
With such a low Internet speed, would upgrading my LAN help at all? I was told from my ISP that the Gateway has a 100Mbit/s rating. So my inclination is no, it wouldn't help at all. I'm just trying to find where the bottleneck is, and if the problem is with my connection, or a few of the players.
Sidenote: Where are some good resources to learn about networking and server hosting in general?
