Scotty,

A number of months ago you helped me with changing out a hard drive, airport card, etc. on my iBook.

Do you work with home wireless networking?

I am having difficulty with keeping a consistent signal.  Some times my mac mini does great . . . connects and navigates very fast.  But at other times it will just get stuck.  This "slow/fast" situation will go back and forth within minutes of each other.

Mostly I am the one having problems, but other of my family members who are connected wirelessly will also some times have problems.  So, I don't know if the problem is my computer or the router we are using, or something else.  I was having the trouble before and bought a new router (a mid-cost linksys) thinking that might be the problem.  Sometimes if I shut down my computer and reset the router it works normally for a few minutes, but then goes back to giving me problems.

Yes, I can assist you with the in home network.  Overall, I'm not a very big fan of linksys routers.  I've posted several entries on my answers section of my website concerning how often linksys routers fail.  Personally I would suggest looking at the airport extreme router.  It's pricey but does a great job.  If your home is over 3000 square feet, you may need to look at an additional repeater/extender such as the airport express.  

Other contributing factors can be the building materials of your home such as copper pipes, plaster wall thickness, metal interference, or large surface mirrors.
