Can an old and upatched (assume a 15 y.o. TP-Link: so plenty of vulnerabilities) be breached given:
- no physical access
- WEP is disabled
- WPA is up but password is not crackable via
aircrack-ng

Given the other side of the router is attached to the internet, I'd say, yes.
The list goes on and on...
In addition to attacks on the WAN/LAN port through Ethernet, it's also possible that the wireless firmware has exploitable bugs that can be used without associating with it. I believe there was some news recently about some Intel wireless NIC firmware or driver that had some bugs that could be exploited by crafting malicious wireless frames.
