I tracked down the issue where WiFi would fail after suspend in that it doesn't associate anymore (tries to connect but fails), and it's a bug in wpa-supplicant that was fixed in the current version (Ubuntu uses 2.1, newest is 2.3). Replacing Ubuntu's wpa-supplicant 2.1 with Debian's wpa-supplicant 2.3 and rebooting immediately fixed the issue. I know that at least some people here had this issue...
