GBerry Posted January 14, 2008 Share Posted January 14, 2008 We have two computers connected to a router, which in turn is connected to a cable modem. When only one computer is on, things are fine, but when both are on, things become very slow. I ran a few speed tests at http://www.speedtest.net/, and here are typical results (the average over a few tests) One computer switched on: Download speed ~ 1000 kbps Upload speed ~ 120 kbps Ping ~ 100ms Two computers switched on with the second not being used: Download speed ~ 900 kbps Upload speed ~ 80 kbps Ping ~ 1000ms Now, without really knowing a great deal about networking or what ping means, it is obvious that this is the most noticeable difference here. Can anyone give an explanation of this (and preferably a solution too!)? Thanks. Link to post Share on other sites
badbinary Posted January 14, 2008 Share Posted January 14, 2008 there are two main kinds of networking devices that split up the network connection, hubs and switches. a hub works like a cable slplitter, it just splits it up and all the traffic goes to everything. a switch is like a hub with a traffic cop, it sends the traffic in the direction it needs to go. your router has a built-in hub to share the internet on. what this means is that even if the other computer isn't being used, all computers connected are being sent all the data packets that any single computer on the network is requesting. so, in a nutshell, get a better router, or get a network switch.

GBerry Posted January 14, 2008 Author Share Posted January 14, 2008 Thanks for the explanation! We just recently bought this router in an attempt to fix the problem - is it not good enough? Is this definitely the source of the problem? And how can I find a router that would improve things? Link to post Share on other sites
badbinary Posted January 14, 2008 Share Posted January 14, 2008 ahhh, you're using wireless. my above explanation only really applies to wired networks. all wireless routers are simple hubs. the more devices connected, the more latency (higher pings). i don't have enough personal experience with wireless routers to suggest one, sorry.

GBerry Posted January 14, 2008 Author Share Posted January 14, 2008 Actually, although the new router has wireless capability, both computers are wired into it via ethernet connections (along with an xbox 360). This was the router that was recommended to us by the guy in the shop, but the wireless side of things is not necessary. Link to post Share on other sites
stormy13 Posted January 14, 2008 Share Posted January 14, 2008 If you're not using the wireless side, make sure you go into the routers config settings and disable it if you haven't already. If you haven't then that could explain the problem as most routers come out of the box with the wireless wide open, meaning anyone and their brother can connect to it if the pick up the signal.

GBerry Posted January 14, 2008 Author Share Posted January 14, 2008 Yeah, I've done that, thanks stormy. So if I was to get this router to replace my current one, should that fix this problem? Link to post Share on other sites
roleo Posted January 15, 2008 Share Posted January 15, 2008 Don't think it's the router. I have a WiFi router/modem, ADSL not cable, and do not have the problems you've got; Lan has 2 WiFi pcs 1 wired pc and 1 wired printer. You should check cable modem setup or your service provider.

GBerry Posted January 15, 2008 Author Share Posted January 15, 2008 Yeah, I've done that, thanks stormy. So if I was to get this router to replace my current one, should that fix this problem? Can someone confirm for me whether or not my current router is a "hub" or a "switch"? I've looked in various places but can't find a clear answer one way or another. Link to post Share on other sites
