Set up a SLAVE router connected to an WAN port in wall that connects to MASTER router

[Badger]

Basically I have now 3 routers on the same network. 2 just wasn't fast enough, so I connected this 3rd one up in my room via the WAN port in the wall. I connected it from that to the LAN in the SLAVE router. It seems to be working, I have the SSIDs different, but either one seems to work when connected to it. This is the only thing I get when logged in on the SLAVE router's IP:

Is that fine or do I need to do something to get rid of that? I have all the same channels, security, pass-phrase and have disabled DHCP on this SLAVE router. I have also assigned it 192.168.1.3 while the MASTER router has 192.168.1.1 and has DHCP enabled. Thanks. - Badger

Speedtests seem to be showing a 10Mbps speed incrase on both ends (download and upload), so I think I got this all right then?...

Please confirm the issue. I'm having a problem understanding. Are you asking if the error stated is good or if you're connection setup is good?

If what the image I posted really matters? Not sure what it means, but I'm pretty sure my network increased with the settings I've set up, so I want to know what that icon means and if it has any real meaning or problem attached to it. Only verizon router users would probably understand though :/.

Is it connected wirelessly or through ethernet? It says to check your broadband connection so I need to confirm.

It's connected through ethernet through WAN port in the wall which connects thru the LAN port on SLAVE router. I appreciate you looking into this for me pal
