Using a wifi router and ethernet at the same time

Hello,
I get my internet from a cable modem thru Comcast. My house has a smart panel with 8 LAN ports, each going to the 8 rooms in my house. The cable modem links directly to an 8-port hub which allows 8 lines to feed each of the 8 ports in the house's smart panel... so every room has a live ethernet wall jack.

In room #1, I have a netgear wifi router connected to the wall jack. The router supplies the wifi network, and also has extra ethernet ports which I connect to my PC.

Everything works fine!!

Here's my problem. Let's say in room #2 I want to connect a laptop to the ethernet wall jack. I do that and the laptop recognizes an "unidentified" network... but does NOT see the Internet. I can't get the Internet!

But when I take the laptop to room #1 and connect it directly to the router via ethernet cable, the Internet is seen (easy plug-n-play)!

Why can't any of the wall jacks in the other 7 rooms connect to the internet???

I realize I can fix this by putting the router BETWEEN the cable modem and the house's smart panel... instead of its current location in room#1.

But why can't I place it there in room #1?? Even though the router is in room #1, shouldn’t all the other rooms have internet? Isn't the cable modem supplying "internet" to all the rooms??

THANKS in advance for the education!!
