After reboot, internet not working

I thought, hmm, I’m going to reboot my Cox modem like the letter from Cox said, to get faster speed. Seemed easy enough. Nope. Zero internet connection. Computers see the router, but router not connecting to internet. I’ve powered things off, unscrewed cable to the wall, started one, etc. Same cables. When router is off, the Cox modem’s globe button is lit. When I plug router in (with modem off or on) the globe on the modem blinks. 

I did pull out a thumb drive and hard drive and those cables out, but no cable changes from modem to router  

Cox modem - NetGeat CM500

Router - TP-Link Archer C3200

Cat cable is 5. Can I put a 6 on there, or is the cat number dictated by modem?

    Cable is the yellow one that came with the router and modem and router have yellow around input  hole ;-)

      I don't think yellow is an official or certified standard, but a contrasting color is to distinguish between switch ports (LAN) and WAN ports (ISP).  Using yellow, Cox is indicating the yellow cable goes to the yellow WAN port.

      So, the yellow trim means it's a wide input hole.

    How long do you allow the Globe light on the CM500 to blink?  According to the User Manual, blinking means it's synchronizing with Cox.

    For now, I'd leave your laptop connected to the modem to troubleshoot.

    Reboot the laptop to renew its IP address with the modem.

    If there is still no Internet, call Cox to "reprovision" the modem.  Mention you've rebooted and reset multiple times.

    How many splitters do you have on your coax?

    Modems don't "dictate" the category of your cable.  The modem and router will negotiate a speed based on capabilities.  For example, you could connect a Cat-4 and your equipment will negotiate 4 Mbps.

    Cat-5 and -5e cables are essentially the same; however, 5e is twisted tighter to resist interference.
