i installed my LEDE-Router in "Client Mode" as described in the Quick Start Guide and connected it through one of the LAN ports to my main router.
Everything works as expected, except the "Network Diagnostics" and downloading Package List and Packages through the webinterface and retrieving the Time via ntp.
Thanks, but DNS is not the problem.
The router works in client mode as WLAN repeater, including DNS.
Everything works on my laptop, i get IPs and can surf and ssh to the internet.
But i can not even ping the default gateway IP from the router itself, although it's working and set correct.
