dhcpcd-discuss

Hi,

I have a problem when connecting to a WiFi AP on an android phone
without root so it's difficult to debug the dhcp server. It seems that
after a while (typically a few hours) the IP address acquired with
dhcpcd is lost. Running dhcpcd -k and then start once more can receive
the offer, but dhcpcd ignores it:

However, dhclient works fine. So how to find out the reason why dhcpcd
ignored the offer? Thanks in advance!
