I just picked up a Galaxy S4 32GB (no GS5 32GB available today) and mine came with 4.4.2 already installed and the WiFi works on mine without issue. Have you tried factory reseting? Whenever I do an OS update I always factory reset, its a pain in the . . . , but it also resolves issues up front so the extra work is sometimes worth it in the end. If the factory reset doesn't work, I would visit your local AT&T store for help.

Assume you tried
Power Off/pull battery/Power On
The next step is - full backup with Kies, Device Wipe, Restore. Just make sure you have a full backup, becuase everything will be erased. Pull out any SD card you have in before the wipe as well, just to be safe.
A wipe/restore usually solves any lingering oddness after a major update.
