OK, I'm glad that you intend to get a WiFi card for the Little Computer sometime
in the future. Let's see what the challenges are with using a workaround first.
A bridge, generically, is a 2 node switch connecting 2 networks with different
physical structure. In your case, you will be bridging WiFi ("input" to Main
computer) to Ethernet ("output" from Main computer, "input" to Little Computer).
An ipconfig log is one of the most basic diagnostic tools in Windows Networking.
Please read this article, and linked articles, and follow instructions
precisely:

If we can't get a bridge working, and you end up using ICS, which is a software
based NAT router, your Little Computer will end up on a subnet by itself. The
Ethernet card on Main Computer will have an IP address of 192.168.0.1 (with
subnet mask of 255.255.255.0, which is the same as saying subnet 192.168.0/24),
and this cannot be changed. Neither the WiFi LAN, nor the Ethernet LAN (if you
use the wired router as a router), will be able to use 192.168.0/24 - you will
have to reconfigure both to allow for ICS on Main.

Another downside of ICS is that you will end up with a segmented LAN. If you
are planning on running Windows Networking (file / printer sharing), that will
be possible only with a lot of additional work. Network Neighborhood, in
particular, won't work properly.
Anyway, let's start with a bridge on Main, and see what "ipconfig /all" looks
like for all 3 computers. That might give us a clue what your problem is. A
bridge will be hella simpler than ICS, since you already have NAT on the WiFi
router.
Here are the ipconfig/all for before and after cases. Note that there are
two PCs connected at the moment. DELL is on both networks and where the
bridge is created.
