Well it would make sense a speed test would show slow speed if you are saturating your network downloading a large file. Also, the download speed you get depends on the server you are testing from. I would normally suggest to do a Cox speedtest, but seems they shut down their servers and outsourced to Highspeedinternet.com which is a 3rd party internet reseller. I would trust speedtest.net or fast.com more.
Let me clarify. I download a steam game, I get my full gigabit speeds. then the speeds drop to 30mbps. Or I download something on my VPN. speeds drop to 30mbps. Then I stop downloading the steam game or get off the vpn and do a speedtest on my desktop, phone and laptop and they all get 30mbps.
My router shows active traffic and it also shows a drop in total traffic to 30mbps when it happens. When speeds drop it comes back within 5-10 minutes but it's happening in a loop.
It's happening right now and the modem status is the same as the pictures I sent earlier. The event logs say a lot of:
-DHCP WARNING - Non-critical field invalid in response
-TLV-11 - unrecognized OID
-DS profile assignment change. DS Chan ID: 32; Previous Profile: ; New Profile: 1 2 3
-Started Unicast Maintenance Ranging - No Response received - T3 time-out

What can you see that OP hasn't already posted?

Did you bypass the router?

Not yet. It happened 5 minutes ago and I went to plug directly into the modem but the speed came back. I'll try to catch it and respond.

Now that I think about it, if the problem goes away when you reboot the modem, and you have to reboot the modem to bypass the router, then bypassing the router won't help isolate the issue because you don't know if the problem goes away because the router isn't in play or because you rebooted the modem. Still try it because if the problem does NOT go away, then that will tell you it's a modem/signal/ISP issue and not your router. However if it DOES go away, that doesn't tell you it's a router issue. The only work around I can think of is to rent Cox's panoramic gateway for a week and see if the problem happens. If so, then it has nothing to do with your router and is up to Cox to fix. Otherwise they will probably just blame the issue on your hardware. Sorry I don't have a better answer for you. You can also try contacting Cox, but I don't see what else they could see or do other then scheduling a technician. Hope I am wrong. good luck.
