Wireless connection problem

http://forums.fedoraforum.org – Hi all, I recently switched to Linux, and FC11 is my first Linux distro. I was having some trouble loading web pages before--specifically, it was taking a relatively long time. So, of course, I went to find out why this might be, and how I might fix it. Someone suggested editing the resolv and modprobe files. However, when I made the changes and restarted my computer, I had no connection to the internet, the NetworkManager icon was gone from the toolbar, I can't use "yum" because it can't find any mirrors, and I can't use any rpm commands either (presumably for the same reason). Basically, most likely due to my limited Linux knowledge, I can't install anything to fix the problem. Am I up the creek, or is there a way to get my connection back/restore my old resolv.conf/modprobe.conf files? I would post outputs from "lspci" and such, but...well, you know. (HowTos)
