See that's your entire problem right there, you're in sales. Your incentive is to drain every penny you can out of customers through useless up-sells and selling hardware to get the service they're already paying for.
You literally just argued that if your 600mbps router only supplies an 80mbps connection then your 600mbps connection is 80mbps. And speed isn't divided equally by the number of devices connected either, that's just ridiculous. The impact of a connected but idle device is minimal. Also, why would you need 600mbps for only 4 devices? You could stream 4k video on all four devices 24/7 and you're still not using even a quarter of that bandwidth; you're looking at a recommendation of only 15mbps to 25mbps per user for a 4k-viable internet connection.
Here's a ping to my stock ISP-supplied router on another floor and three rooms away via wifi:
It's obviously impossible to improve a 0% packet loss, switching to a wired connection would be a considerable cost for minimal benefit (though admittedly that ping is unusually good, I'd normally expect slightly over 1ms average). I'm also getting over my advertised speeds according to fast.com and speedtest.net despite being on wifi and running through Mullvad so I suppose the problem might just be that I'm not using whichever scummy ISP you work for.
I have a home office and have work from home (or hybrid) for pretty much my entire career, even before WFH was normalised. I can assure you a wired connection is not a necessity to work from home.
Bandwidth is the amount of shit the modem can pull down and thereafter divided per client further subject to the limits of the service itself and any chokepoints in the network with data hitting the client no faster than the slowest leg.
As far as wifi 5/6Ghz is fairly fast but good for no more than 100–200 ft inside and oft less depending on material in between and conditions and subject to interference to boot. Most people in multi story dwellings have poor connectivity over 5Ghz upstairs without a second AP on that floor and rely on slower 2.4Ghz and furthermore may have a limit to the connectivity between AP which effects downstream clients.
That is what I meant by the 80MBps if the link between Router and AP is 80Mbps the AP can only provide a maximum of 80Mbps connectivity with the outside world shared between all its clients no matter how strong its connection. This is why I suggested a wire between router and AP. Factually real world clients usually have 20-300Mbps over wifi and need nicer clients AND equipment to provide good service whereas wires provide 1Gbps over cheap as equipment from 10 years ago.
P.S. I worked in support and had a really good solve rate I made money mostly by helping people improve their service in tangible ways that made sense to them. Just because an industry is scummy doesn't mean everyone in it is.
