Wirless router not working after Ethernet cable disconnect

Witless router problems

Hi, guys I'm having a problem with my netgear wireless router. It's connected to a cable modem.

The wireless router is labeled with four LAN ports on the back and one port labeled as Internet. I have an Ethernet cable running from my cable modem to the Internet port on wireless router.

I have two laptops, iPhone and desktop running on the wireless router, desktop is hard-lined into LAN port 1. Everything else is wireless, One of my laptops has been running really slow lately.

I disconnected the ethernet cable
 from the Internet port on my router and plugged it into the slow laptop to do a speed test. 

So speed test was done when I plugged the Ethernet cable back into the Internet port on my wireless router my other laptop won't connect to the Internet, if I put the ethernet cable into LAN port 3 my laptop has internet connection but my iPhone does not if I plug the Ethernet cable into LAN port 2 my iPhone had Internet connection but my laptop does not.

Any ideas how to fix this?

If you plug the cable modem ethernet cable into a LAN port of the router then only one of the devices will get to communicate as the modem is a single IP device.

So you need the cable modem connected to the WAN / Internet port of the router if you're going to share the connection among several devices.

I would turn everything off for a couple of minutes, then start the cable modem, after a minute or two start the router wired to the cable modem, after a couple of minutes bring on your other devices.
