The router is not the youngest one but I think that doesn't matter.
Channel ; 11 (2.4 Ghz)
RSSI ; -66
RSSI -66 is not perfect but a good "standard" value for the signal.
If the problem occur in times the computer is the only client in the wireless it could be caused from interferences in the used 2.4GHz radio band; e.g. neighbour wifi networks or other radio equipment uses that band too.
2.4GHz radio equipement is e.g. cordless phones, Bluethooth units, cordless doorbells, cordles mouse/keyboard, cordless headphones and so on.
Also running Microwave oven's can kill your wireless.
You should eventually fix a different channel in your router settings. The used one should have (if possible) a 5 channel gap to other 2.4GHz radio equipment, e.g. the strongest neighbour wireless net(s)
Depending on your country you should try to use:
Europe: Channel 1,5,9 or 13
USA: Channel 1,6 or 11
The periodically scanning for wireless networks of your Mac is a (works as designed) normal behaviour.
Imagine that you have a extended home and two (or more) roaming wireless base stations to provide the wireless seamlessly in every corner of your place. The Mac will scan periodically and if you move it around the house, it provides you on this a constant connection.
