So I'm trying to connect two routers wirelessly. My main router (Archer D7) connects directly to the Internet, whereas my secondary router (MR-3420) needs to connect to main router through WDS. I've already spent a day trying everything I could find online. Here's the current scenario:

Main Router

  1. IP Address: 192.168.1.1
  2. Running DHCP in the range 192.168.1.4 - 192.168.1.200.
  3. MainPC running Windows 10 with Automatic LAN setting is wire-connected to this router..

Secondary Router

  1. IP Address: 192.168.1.2
  2. Not running DHCP.
  3. WDS configured and successfully connected to Main router.
  4. KidPC running Windows 7 with the following LAN setting is wire-connected to this router: IP: 192.168.1.41 Gateway: 192.168.1.2

(Setting IP to automatic on KidPC doesn't work. Setting Gateway to Main router's IP also doesn't work.)

What works:

  1. MainPC can ping MainRouter and access the Internet.
  2. MainPC can ping Secondary router.
  3. KidPC can ping secondary router.
  4. I can see KidPC in the list of connected clients in main router's home page.

What doesn't:

  1. MainPC cannot ping KidPC either by name or IP address.
  2. KidPC cannot ping MainPC or Main Router.

What am I doing wrong?

  • Also make sure you disable DHCP on the second access point... use the "main router" as the only DHCP server. – Attie Apr 9 '18 at 11:55

    @Attie - You are entirely correct. It's too late to correct my comment, so I'll delete and resubmit. – AFH Apr 9 '18 at 12:04
  • The KidPC gateway is wrong: it should be 192.168.1.1, since the secondary router is acting as an access point. DHCP should have made this setting. – AFH Apr 9 '18 at 12:04
  • I had fun and games the other day with Wireless extenders... for peace of mind, I'd recommend just turning it all off and back on again, and see if that helps...... – Attie Apr 9 '18 at 12:20

    How did you cable-connect the secondary router to the main one? See this answer to understand why it's important. – harrymc Apr 9 '18 at 13:30

Apparently your secondary router is not acting as a router. It's just a wireless bridge.

So your KidPC should obtain address from Primary router and have both gateway & DNS of 192.168.1.1 to work.

If the secondary router is just a cable or dsl router you take advantage of, disabe any other function of it. If it is indeed a wireless router you must either use in bridge mode (Wireless & LAN) or setup a secondary LAN of another range, say 192.168.2.x on its LAN ports and enable DHCP, so KidPC can connect.
