Well, this is a problem for me because I share a C5 cable with my bro... a 50-foot cable. To compound the problem, our computers are connected to a switch, which slows things down even more! (This doesn't keep us from playing multiplayer games all the time, however, because they don't require this much bandwidth.)
So, what to do? Here's a list of things you could do if you had the same problem:
- Upgrade your network equipment. Even if you don't want to go with the new CAT6, getting newer routers, hubs, switches, etc. can give you significant speed increases.
- Get routers. Using a hub or switch to share your Internet? Routers are much more advanced and faster than switches, for a number of reasons. Here's a good article about the differences between routers and switches.
- If you have a broadband router that you use to receive the Internet with, it probably came with some software that you can use to block certain things through the router. Just run the software and follow it's instructions for blocking p2p/filesharing (it'll usually have a pile of categories that you can block by clicking their checkmarks).
- Ask your netmate to please limit his downloading to times when you're not using the network, or ask him to set his software to use less bandwidth. In the long run, this is probably the best solution, because it's the least intrusive.
These are my thoughts (and rants) on this subject. Let me know what solutions work best for you!
