I am aiming to get some type of mini-pc and install some open-source router software on it in the near future to replace the default AT&T router I have now. I have a DSL subscription with AT&T and an rj-11 6P4C cable. Most of the mini-pcs that I have looked at only feature ethernet (rj-45) ports. I have found rj-11 to rj-45 converters online for very low prices.
Before I shell out roughly $200 for a mini-pc, I want to know:
1.) Is there any reason why one of these converters would not work, or work very poorly?
2.) Is the 8P8C going to be superior to the 8P4C connector?
3.) Could they possibly introduce a bottleneck into my network? I only have a 100mbps connection, and almost never need that much speed. Regular Cat5 cables can handle as much.
4.) Are there any other likely hiccups you can foresee?
Thanks in advance for any help you can offer.
