Making my Dell Inspiron 8500 function

I’ve been wretling with a Dell portable this month that has had intermittent network access problems. I finally hit on a solution kind of randomly and the Dell support forums suggest that maybe it is the fault of the Internet Connection Wizard — Re: Inspiron 8500 — disabling Network Bridge – Inspiron – Network – Dell Community Forum — hard to believe but something clearly did establish a bridge on this machine and it has made networking unreliable. Why would I ever want to bridge networks on my laptop — sure I supposed there is a geek reason to do it, but why would a “wizard” ever leave me in this config?
