I’m using WiFiMan to diagnose a slow network. When I do the speed test in WiFiman, the download speed is only 3 Mbps, but the PHY speed is 174 Mbps down. Would this imply it’s an issue between the router and ISP vs between my phone and the router? I can’t seem to find any real concrete info on what PHY speed means on google, it makes it sound like these should be the same speed, unless PHY is faster than what your ISP speeds are.
It’s a Wifi 4 C3000Z on centurylink if it matters.

Start by testing using a pc directly connected to router with Ethernet cable to determine service speed being delivered to the residence.
This. And there could be multiple factors why your Wifi speed is slow, a main one being distance between your PC to modem l, how many walls between, other electronic devices that are emitting or could disrupt whatever ‘band’ frequency of that connection, the modem specs, how many active connected devices to it, the router specs, (rarely the issue for individual/residential) the Cat cable being used between modem and router.
