    Cable-Modem question

    So I recently moved into a new appartment way off campus. And have therefore lost my 500Mbit connection. Along with it's glorious(at times) latency.

    So here's the real problem... I know cable-connections arent anywhere near as fast as an ethernet connection, but I also know that my ping/latency to the world shouldnt be hovering in the 200-300's. But you cannot say no to a free cable internet connection when you're a college student.
    But this connection is horridly slow. I can download 200-300-500KB/s on occassion but only after a solid delay before actually making the connection to start the download.
    My pings are on the order of 200-500 always on whatever games I *attempt* to play online. And worse yet, the situation at hand has made it practically impossible to work from home via an ssh console.. it's just too damn slow, even typing I have lag before seeing the keys. (I had none of this while on the ethernet on campus)
    So as far as I can tell, here's how I'm hooked up:
    Plug into wall from computer... then off to one switch/hub that I can ping, but beyond that I'm unsure. We dont have a cable modem/router in our appartment, it's likely somewhere else in the appartment building, connected to several hubs/switches before it gets to each room.
    I realize things will slow down when there is that much traffic trying to be pushed through one or two routers.

    Suggestions??

    (I was thinking that I might be able to 'bypass' all of those switches/hubs by purchasing a cable-modem/router, and plugging it into a cable jack, then using that as a hub for the 3 rooms in my appartment, any idea if this may work for me? I guess this is the real question at hand..)

    Thanks in advance,

    Sounds like the cable modem is your only salvation from your high latency, assuming that you can do it.

    I'd be curious to know if the cable modem method works. In the meantime, test your line speed at a place like DSL reports. You don't have to have a DSL line to test BTW. See if your connection is stable all the time or to what extent it is fluctuating.

    If they're splitting the signal among that many people, the issue could very well be LOCAL latency. Too many people on a crappy infrastructure will load up a network like crazy.

    Try this - when you're at school, do a pathping from an XP machine to a few different common sites that you can ping, like say, yahoo.com, dslreports.com, www.gotapex.com, etc. Collect the results in a text file, and then do the same thing from home.

    Pathping is a handy (XP only) tool that will do a tracert & ping each hop. When you compare the results, this can give you a good indication of where the slowdown may be occurring. If you're not sure how to interpret them, post the results here & we'll all have a look.

    Also, for SURE you want to get yourself a good firewall - if you're all sharing the same internet connection, then you're all on the same LAN. It's a pretty easy task to break into an unsecured machine on the LAN.

    However, even worse is the ability to sniff the traffic - I'm afraid there's nothing you can do about that unless you want to spring for a separate connection. Most vulnerable is your email password, which is sent in clear text even if your mail is encrypted.

    As for plugging a different router into the cable jack - I say give it a try. If you can isolate yourself from the rest of the network there, it will probably solve at least a portion of the speed issues you're seeing, and will certainly be more secure.
