Connecting a switch to a cable modem

I am trying to get the following config to work at home:
Cable modem -> 8-port unmanaged switch -> 6 ethernet connections to ports within the house.
One of these ports goes into a wireless router (Main floor) while the modem and switch are on a lower floor.
I cannot get any port other than Port 2 to work at the same time (port 1 is the input feed from the cable modem).
My challenge is that I cannot keep the wireless router downstairs as I will not get any signal strength on the floor above.
What si the best possible way for me to get coverage other than using multiple WiFi Access points?
I also think this config above is not secure since all the ports are not protected from the outside world.
Is this a setting from my ISP or the cable modem or would this be a problem with any ISP?
Appreciate any thoughts

You have not provided enough information to answer your question. Of course it being an unmanaged switch, its very possible, what you want is not possible with the hardware you have.

Your wireless router should be directly connected to the cable modem. You cannot install a switch in between them, and expect all ports on the switch to access the Internet and/or your LAN. IOW you need to install the switch on the LAN side of the router, and not on its WAN side (unless you know what you're doing).

You will probably need to get a second router. It does not need to be a WiFi router, but you need to have a router between your cable modem and your switch.
Reasoning:
Most residential ISPs only offer a single IP address to their customers. When you connect a switch to your cable modem each device connected to the switch attempts to get an IP address directly from your ISP. One device will get an IP and the rest will be left withouth.
When you connect a router between the modem and the switch the router gets the 1 IP address from your ISP and creates a new network with its own private pool of IP addresses that all of your devices can connect to.
If you do add a second router you will want to disable the DHCP server on your WiFi router and plug the Ethernet cable into one of the LAN ports instead of the WAN port.

Normally ISP modem are routers. Think if you have the modem and 8-port unmanned and every one has LAN IP 192.168.x.x or 125.x.x.x. This is managed by the DHCP on the modem router and probably wifi combo your ISP install, so you are covered by the firmware of that device.
Wifi range and signal could be improved by channel management. Install some kind of wifi analyzer on your cell phone and see a free channel, once you solve the collision problem and is a big one, you can see if your modem is set up and your wifi you plan to connect to the unmanned 8-port has some join technology to work as one wifi network. I think you'll be good that way.
