I have a problem with my router (Networking) and was wondering where would be a good place to ask my question? Obviously not on stackoverflow =).
Sorry this question is short.
Configuation problems can be posted on Superuser.com.
From the superuser.com FAQ:
Super User is for computer enthusiasts and power users. If you have a question about computer hardware, computer software, personal and home computer networking
If your problems are administrator related I would recommend serverfault.com. FAQ:
Server Fault is for Information Technology Professionals needing expert answers related to managing computer systems in a professional capacity.
I personally would ask on either Super User or Server Fault, depending on the scale of your networking problem, but you should have a look over that list to see if there might be something more applicable
