Bad Ethernet cord? Advice please!!

Slow Orbi AX- could it be Ethernet cord?

Here is the deal. Have has Orbi (RBK853) since June - ran flawless. ISP had a wide outage last week. Came back fine. Now 2 days in a row our internet has slowed to a crawl (download, upload fine). Reset router and modem- nothing. Then I unplug Ethernet cord to modem and plug PC into modem. Speed is good. Plug Orbi back into modem and then it’s fine. What would cause this ? Resetting does not work, but Unplugging Ethernet to modem and plugging back in does?
Both today and yesterday unplugging Ethernet work- has this happened to anyone else. Advice please!!

Your ISP Modem already has a build in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

I Must have given you wrong model # - because it is 💯 only a modem.

Yes, I just checked and it is actually the arris TM1602- sorry was away from home and looked up off spectrum site (similar looking modems). Not a router (neither is the other model)

Ok.

 

Well if the system was working ok before this ISP outage. I would represume if it's not working now, then the ISP services need to check into this. 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.

They think it’s port in the modem, sending a new modem.
