The Lenovo connected to the Panoramic 3 days ago. Something had changed.
Did you move the Leno since 3 days ago? Sometimes distance or a stronger neighborly network on the same channel will show in the list.
Does the Panoramic "channel hop?" If the Pano automatically changes to a less crowded channel (since 3 days ago) and your Leno is "hard set" to an Ad Hoc channel, your WiFi may not appear because it's "listening" on a differing channel.
Ad Hoc Channel. Run devmgmt.msc > Scroll to Network Adapters > Locate Wireless NIC > Properties > Advanced
Note some drivers for wireless adapters don't have an Ad Hoc option so this may be all for nothing.
Were the Pano networks (2.4 & 5 GHz) always 2 separate networks or did you recently separate 'em?
How did you "reset" its NIC?
