How can I reduce chattyness of udhcpc?

Installing and Using OpenWrt Network and Wireless Configuration

@mariano.silva There are two issues here:

  • First, your ISP's lease time is 300 seconds, which means udhcpc will attempt to renew starting 180 seconds after the lease is granted. This is the correct behaviour and you cannot (nor should you) change that. udhcpc will inform you about these matters in the log.

  • Second, sending renewals to 0.0.0.0 is the same problem I've been having. More info on the reason and fix here https://github.com/openwrt/openwrt/pull/1017. If you upgrade to any version from e4259be or after, you'll hopefully have your problem fixed.
