How fast is a Cable Modem

February 28, 2010

There is no single answer to that one, depends who you ask… You connect your computer (Mac or PC) to the CABLE / DSL modem via your standard 10Base-T Ethernet connection. So, how fast does it really go?

Well, I’ve seen it go over 650Kbytes / sec. Web pages are usually 20 – 40 kb / sec. I’ll just list different results, which can vary based on several factors.
