The wireless network in my home was set up by a third party with a main wireless router (Router 1) connected to the modem, and two secondary routers (Routers 2 and 3) located in the bedroom connected by ethernet to Router 1.

The three routers support separate wireless networks with different SSIDs and passwords.

After replacing Router 1, Router 2 is no longer able to connect to the internet - the wireless icon on windows shows "Connected but no internet access". However, Router 3 is functioning fine and is able to access the internet.

Router 2 is a TP-Link Archer C2. I'm not sure if the following information is relevant, but:

  • DHCP is enabled on Router 2
  • The status page on Router 2 shows that it is unable to get a WAN IP address, with IP Address / Subnet Mask / Default Gateway / DNS Server showing up as 0.0.0.0
  • Connection type is Dynamic IP
  • I have clicked the "Renew" button on the WAN Settings page but the addresses remain as 0.0.0.0
  • It is not a physical cable issue - have tested with working ethernet cables
  • The physical internet status light shows as green on the Archer C2
  • Running ipconfig in cmd shows an IPv4 address - 192.168.1.113

I would greatly appreciate any help in resolving the lack of internet access on Router 2. I'm quite clueless as to how it was set up, but would prefer to keep the current separate wireless network setup.

Please do let me know if any more information is required. Thanks in advance!

EDIT: The router settings page on R1 shows that R2 is a connected device, and recognises it as an Archer C2. Not sure if this is relevant information.

  • Is a DHCP server enabled on router 1? If you connect a computer to the same Ethernet port on R1 (that is, unplugging R2) does the computer obtain a DHCP IP address successfully? – grawity Sep 3 '18 at 8:09
  • And how is router 3 configured? – Fanatique Sep 3 '18 at 8:28
  • @grawity - a DHCP server appears to be enabled on Router 1. DHCP configuration on the router settings page has been set to automatic, and upon connecting a laptop to the same ethernet port as R1 the laptop is able to access the internet (and accordingly, I assume, obtain a DHCP IP address successfully. – James Craig Sep 3 '18 at 14:54
  • @Fanatique - Router 3 is an Archer C5 and also has DHCP enabled. Similar to R2, it connects to an ethernet port on R1. Not too sure what other configuration settings are relevant - please let me know! – James Craig Sep 3 '18 at 14:56
  • Do you want these setup as different ssids? I would think bridged routers on separate channels setup for AP roaming would be optimal. – Tim_Stewart Sep 5 '18 at 15:36
