From Bradley Mitchell, your Guide to Computer Networking
When someone mentions "computer networking," we picture high-speed communication using cables or wireless connections with computer chips or cards talking over some protocol. But what if we didn't have integrated circuits for networking - how would a network function?

Implementing a Computer Network With Musical Instruments
While far from being a practical solution, one graduate student decided to build a demonstration network using musical instruments as the communication mechanism between computers. It even runs Internet Protocol... sort of.

Readers Respond: Wireless Network Security Hacks/Stories
If it weren't for the firewall on my computer, which alerted me of an unusual connection attempt that I blocked, my secure files would have been compromised. "I checked my router's logs and found an unusual IP address visiting websites I had not used that evening. I am concerned about the files on another computer in my network running at that time with an inferior firewall, luckily it had no sensitive files on it. I know the hacker is still around, makes one think twice about trusting neighbors. Luckily I was able to kick them off the router before they did too much damage. Since then I have found a slew of vulnerabilities (WPS, UPnP, TKIP, ect...) with my router which i have (hopefully) fixed." -Scotty

Readers Respond: 802.11n Router Experiences
"It would seem routers in general are unreliable with some just worse than others. Having said that, I have two DIR655 D-Link routers. A v1 and v2 hardware. The v1 has been in use for nearly 10 years the other for over a year. No problems on either one of them. Been thinking of getting a new one to take advantage of the new ipv6, but scared of getting a piece of junk." -SGO1

Tips for Maintaining Wireless Home Networks
It's a lot more fun setting up a new wireless network than it is maintaining an old one. Not only is a good maintenance plan is essential to keeping a network running well, it's also possible to significantly improve its capability, performance and security with the right upgrades over time.
