Had to buy new modem. Now wifi strength on nighthawk took a major dive.
So my modem crapped out on me in the middle of the night yesterday. Called cox to troubleshoot and they couldn't figure it out so they had to send somebody out. Already knew it was the modem so went ahead and bought a new one before they showed up.

Anyways, got the new modem running and all of a sudden my wifi strength is garbage now. On my phone next to my router and getting only 50 download speed. But anything plugged straight into router and modem is getting 300, what I pay for.

Any suggestions on what could be causing this?

ETA: Router has most up to date firmware.

Does the new modem have a wifi router built in?

No. Just a modem.

They have told many times that I need a new modem. I never did and it still works. Anytime, they can`t figure it out over the phone, that's what they say. A couple of days later, everything flying like normal. They do this to most people who do not rent their modems from COX.

What modem did you get? Is QoS enabled on the router?

So i had done my own troubleshooting even before COX came to my house. When I hooked a laptop up the modem it was issuing an APIPA address. And when I had COX on the phone they were showing a good signal coming through to my house and they also hooked the meter up my house outside when they got here and was also showing a good signal and 0 packet loss.

So I myself thought it was the modem before COX even said anything. And the COX guy that come over initially thought it was the router because of Netgear's recent firmware update causing problems but after I told him what I had noticed he turned his attention toward the modem and started to agree with me.

There's an app called WiFiman that lets you test the speed between two devices on your WLAN. This is a WiFi speed test, not an Internet speed. The modem is completely eliminated from the equation.

Install and run the app on two devices. You'll get a popup asking if you want to run a speed test between the two devices.

For reference, I'm getting around 300mbps between a Samsung S10e and a Pixel 3a.

That sounds like a WiFi problem, not a modem problem.

This started after the modem was replaced. The Cox guy hooked up his meter to my old modem and was getting nothing from it. It was dead. But before all of this I was getting almost 300 speed on any device being right next to the router. Now 50 like I said.
