I live in Manhattan and my TWC/Spectrum provided Arris TG1672 router/modem combo doesn't provide enough coverage in my small (800 sqft) but concrete walled apartment. I'm thinking about turning off the wifi on the TG1672 and adding a TP-Link Archer C7 wi-fi router. 1) Can I do this? 2) Will this help? 3) How do i do this? Thanks!

In most cases it will make no difference. First when you deal with concrete walls the 2.4g signals will penetrate better so you will likely see no benifiti to the 5g band on the tplink device.

Without a lot of digging in the fcc database I am going to bet the TWC device is putting out very close to the legal maximum power. Buying another router will not increase your power output so it is unlikely to increase the ability to penetrate concrete. Even if it did you still have the problem of the end devices not having enough power to send the signals back.

Maybe you could look at powerline devices to extend the network to another room. You could then put a router/ap there or they make powerline devices with AP built in.
800 sqft is nothing, you cannot move the Arris to a more centrally location?

But sure, turn off the Arris WIFI and add your own box, but now in the middle of the building... and configure it as an ACCESS POINT. You have a working ethernet jack at this central location I hope.

Sadly, I do not have a working ethernet jack that's centrally located. Would my own router make a difference if it's basically right next to TWC's modem/router?
