Tips and Troubleshooting

Experience is the best teacher...

On this page I'll include tips and tricks I've learned. Where appropriate, I'll include steps or pictures to help clarify my explanations.

Please feel free to contribute your own tips - I'll post the best ones so everyone can see them.

Modems - Speeds

The speed of any connection is dependent on the modems involved (yours and the ISP's) and the telephone line quality. The further your modem is from the central office, and the noisier the line is, the slower the connection is. And of course you can't go faster than the slowest modem in the connection (yours or the ISP's). Of course almost any digital connection is faster than a modem.

DSL - Digital Subscriber Line

Digital Subscriber Lines are digital connections which are superimposed on analog telephone lines. This is a good technique to provide access speeds faster than modems, and allow simultaneous use of the Internet and you telephone.

Cable Modems

Cable "modems" are not exactly "modems", in the sense of "MOdulating" and "DEModulating" analog signals to transmit digital information. They perform a similar function, acting as in interface between a local digital source and a digital line. These "modems" provide very high line speeds compared to analog modems, and therefore are a very good way to connect to the Internet.

Internet Connections - Overview

The Internet is made up of millions of discrete parts. Most of us are only concerned about our connection to it (analog modem, DSL connection, or Cable connection - or maybe even a T1 connection) by way of an ISP (Internet Service Provider). But an ISP has to connect to the rest of the Internet by connecting to a backbone segment, or to a higher-level ISP. Usually this involves one (or more) high-speed lines from the ISP to a router, switch, hub, or computer connected with very high-speed lines to other routers, switches, hubs and other computers.
