I am going to go back to the drawing board.
Forget about wpa_supplicant. I've turned encryption off on my router, and I just want to be able to establish any communication. I previously had the hardware working using the same OS, so it isn't a driver issue. I am sure I am making a silly newbie mistake since iwconfig doesn't even show being connected to my network (ESSID is "wired"). When I was earlier messing around with wpa_supplicant, I was able to get it to use ESSID "wired", but as I said, I want to start off simple first.
[root@michaels ~]# iwconfig
lo no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=27 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
eth0 no wireless extensions.
My ifcfg-wlan0 file is as shown.
[root@michaels ~]# cat /etc/sysconfig/network-scripts/ifcfg-wlan0
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
