I'm running in the following problem:

  • I have a Archer C7 v1 as main router with stock firmware doing DHCP.
  • I have a second router Netgear WNDR3700v2 running LEDE and I'm using it as an Access Point.
    On the Netgear WNDR3700v2 I set up everything SSID's and all and all is working fine.
    But when I change the SSID with LuCI DHCP stops working on both 2.4 Ghz and 5 Ghz.
    When you change the SSID with the CLI DHCP is working fine after the change on both 2.4 Ghz and 5 Ghz.

Anyone has an idea what this could be or experienced the same?

Thanks in advance.

Silly question, but you have made 100% sure you disabled DHCP on the LEDE box, including all the IPv6 stuff?

@alexatkinuk it’s not a silly question, on the second router all DHCP functionality is disabled including IPv6.
