I own one Archer C4000 and one Archer C1900.

I would like to use both in 2 locations in my house to help wifi coverage.

My internet is coming in from a cable modem. I have put the modem into bridge mode so that it's only a modem, not a gateway/router.

Option 1:

Use one router as an access point, and the other as a normal router.

This is easy to acheive. But does anyone recommend which of these models is better as a router and which is better to be the access point?

I am currently using the C4000 as the access point because it has more capable WiFi, but all of the other features are turned off.

Option 2:

Use both as routers on two different subnets.

I've tried to set them up like this: MODEM -> C1900 router -> C4000 router.   But the PC's on the C4000 can NOT see the PC's on the C1900.

I setup a static route on the c1900 to the c4000 but that didn't work. Maybe I did it wrong?

What is the approach to do this so that I can use both as routers to assign IP addresses and allow all the devices to see eachother?

Option 3:

Should I try to sell the C1900 for a few bucks and purchase some other AP / Mesh system to go with the C4000?

Thanks
