I have no problem using a Slate 7 on the same modem. The log is as follows:

It seems to be using IPv6, even though that option is turned off.

Any suggestions?

Thanks!

Hello,

What firmware does the router use? If v.4.7 then may be it makes sense to try 4.6.8 (the latest stable one based on OpenWRT 21)?

Hi,

Please check if the MAC black/white list is enabled by the primary router?

The IPv6 related log is mDNS multicast, it can be ignored.

From the log, the WAN in DHCP mode, udhcpc sends 2 times discover requests for IP, but seems the primary router does not offer IP, so the Flint 2 WAN cannot obtain IP
