Got to buy a new wireless router - other one 2 years old - can't turn it on half the time...But I know nothing about which router is best for under $50.

I use mac powerbook G4, airport, OS X.4.10, have verizon DSL internet. Have a son who likes to plug in his ethernet cable to router to his PC to access internet as well. SO, what's the best router for my scenario, under $50?

Thanks much
