I now have a functioning home wifi with Linksys WRT54G router and XP, 2K, and 98SE computers with HP2510 wireless printer.  I am thinking that I should change to static IP as recommended here http://www.wown.com/j_helmig/guidcnfn.htm by Johannes Helmig.  I'm not 100% sure that this would be a good idea.  Once I had the same IP get assigned to two of my computers and, also, I suppose that dynamic IPs slow things down at least a little.

My question is: does anyone think it would be a mistake to do this or does anyone have any advice doing it?
