Got my promotion!

I'm now a network administrator and I'm drunk on power!  Actually, I'm buzzed on cold pills, but close enough.  My first project as network admin?  Fix one the office wireless networks, one that the original IT guy, the one with lots of experience and qualifications advised my bosses to get rid of because it was too expensive, too complicated and an all around piece of over priced crap.  About a year and half ago we got this dire warning, but someone in the office had insisted on buying a $500 access point that's incredibly unreliable.
Anyway the point is it's my job to fix it.  In theory this'll be a piece a cake, in practice I hope my phenomenal luck will get me through this.  I'm waiting for the router to come in, so I'm "pre trouble shooting"... what fun.  I can't wait to see what happens with this.
