T530 RADIO DRIVER UPDATE
UPDATE (August 2013): While the problem still has not completely gone away, I have noticed that one of the most likely ways to trigger this behavior is flipping the wireless switch while the computer is booting up or resuming from sleep or hibernate. Neither of these is really a good solution, considering that the problem shouldn't be happening in the first place, but it's better than what I had to do before.

The situation you're experiencing can happen when your WiFi router is the first type of device and randomly picks a channel between 52-144, and your laptop's WiFi card is the second type of device and is blocked from seeing anything on channels 52-144. Some took the lazy way out and simply blocked their device from ever using channels 52-144. Some WiFi device manufacturers did just that. The router has to monitor for weather radar, and automatically switch to a different frequency (channel) if it detects radar in use.
WiFi devices are still allowed to use the 5 GHz band, but if they use the frequencies which could interfere with radar (channels 52-144), they have to comply with DFS - dynamic frequency selection. So the FCC took the unusual step of placing new restrictions on the open 5 GHz band. This radar is very useful at airports which frequently suffer bad weather, and is easily interfered with by WiFi broadcasts on those frequencies.
Shortly after the FCC opened up the 5 GHz band, it was discovered that some of the frequencies were useful for a new type of doppler weather radar. The fix is easy: Go into the router settings and change its 5 GHz channel from Auto to something between 36-48 or 149-165. If the laptop can see other WiFi networks, just not this one, and this particular WiFi network is a 5 GHz network, then you've probably run into a problem caused by DFS.
