Hi, david. First question: does the laptop have a physical switch on the
side that turns on/off wifi, the way Dells do?

Try an lspci, and see if it shows.

If it does, wireless will be wlan0, usually. Why your wired ethernet's not
working - look at dmesg and/or /var/log/messages, and see if the driver
was loaded. Next, look at /etc/sysconfig/network-scripts, and see if
ifcfg-eth0 is turned on at boot.
