Simultaneously lan and wi-fi from the same subnet for one PC, how?

Question

WiFi

There is a netbook with ubuntu server 14.04 installed, the netbook has lan and wi-fi (file cleaner, torrent...).
Internet and LAN via zyxel keenetic giga 2 (firmware v1).
it is required through LAN access to the local area and through wi-fi access to the Internet. ideally, this is the aggregation of channels, as I understand it .. but in real life, of course, it is not achievable))
in general, tell me how to implement it. THX.
----------------------
ip route
default via 192.168.1.1 dev eth0
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.36
---- -----------------
Melkij
nothing to draw .. router 192.168.1.1 (distributes addresses via dhcp), beeline l2tp Internet wired 100 megabits enters the wan.
from the router to the PC (1-port 192.168.1.33) and netbook (4-port 192.168.1.36).
one subnet for everything
and for wi-fi phones, tablets, etc.

forgot the most important thing - wi-fi and lan from one router, with one subnet

Answer 1

Theoretically, it should work right away - the Ethernet metric is less than the Wi-Fi metric.
Make ip route, let's see how things are going there.

Answer 2

Aggregation is about something else.
Draw, please, the topology (with connections between hosts and addresses on adapters)
And wifi and lan - in the same subnet or in different ones?
