Rookie question perhaps... What more wires in a CAT5 cable other than TX+ TX- RX+ RX- does a standard IP phone use? I ask because I had one cable run where the PC had 100% connectivity, but when I plugged in an IP phone to the same run, it would not receive an IP (PC was DHCP as well but it shouldn't matter) and resolve to the network. I finally re-punched the wall plate and patch panel and it worked like a charm. I have been combing the web for an answer on this, and the best I found that the phone may require additional wires in the cable if it is PoE, which this particular run is not Powered. Head scratcher for me...maybe someone out there has an answer! Thank you :)
Trying to set up a new wireless network and running into all kinds of strange problems. Connections dropped every few hours! Some machines work, some don't! Can connect to internet, can't connect to router! DOGS AND CATS LIVING TOGETHER (literally). Please help. [more inside]
I need some help on networking and ip addresses. I'm working on a project that uses a RN-XV Wifly module to connect to a home's wifi network. To use the device you will have a GUI that on the back-end telnets to the Wifly module and sends a serial string of commands. So if the Wifly address is 10.1.0.17, it would send: [more inside]
Does anyone know how to access a Synology (or other) NAS remotely -- esp. if they seem to be behind multiple routers in a big network? [more inside]
I want to learn about IP and Network integration for home theater/home automation. Cedia looks like they have exactly what I'm looking for...but not until September. I'm reasonably computer-savvy and a fast learner, so my first choice would be a fast-paced crash course, starting right-the-heck now. In order of preference: Live in-person class(es), interactive learning website or software, book, non-interactive website. Also, location in the Northeast US is optimal but not required. Thanks!

Someone posted a spam comment on my blog that came from IP address "192.168.0.165". Since that IP address is reserved for private networks, how on earth did they do that? Is this "IP spoofing"? If so, how does it work?

Though I'm pretty computer savvy, my lack-of-knowledge about networking keeps tripping me up. Where can I learn about IP addresses, routers, http, etc.? I don't have a specific problem at the moment; I'm just looking for general information that might help someone who tinkers around with web-development and who occasionally needs to get machines to play nice with each other.
