This error indicates that iPXE timed out while attempting to autoconfigure a network adapter.

In almost all cases the method used for autoconfiguration will be DHCP, and you should read the information relating to [[:err:4c1060|DHCP timeout]].

This error could be also a bug in UNDI driver. In this case, the issue can be intermittent. This can be solved by upgrading firmware on network card.

Things to try:

  * Read the information relating to [[:err:4c1060|DHCP timeout]].

  * If you are using IPv6, read the information relating to [[:err:4c0760|router discovery timeout]] and [[:err:4c3b60|DHCPv6 timeout]].

  * After the failed autoconfiguration attempt, check the output from the ''[[:cmd:ifstat]]'' command to see if iPXE is receiving any packets (the "RX" counter) or experiencing receive errors (the "RXE" counter).

  * Test specific autoconfiguration methods in isolation using the ''[[:cmd:ifconf]]'' command.  For example:<code>ifconf -c dhcp net0
ifconf -c ipv6 net0</code>This may give you more specific information about the underlying problem.

  * If this only shows up after a reset when chainloading undionly.kpxe, it may be a bug in your PXE boot ROM. A hard reboot will work as a quick fix. A long term solution would be to replace the buggy boot ROM (either with a newer version or with iPXE). Alternately you may chainload a iPXE image with a real driver for the specific card. This is known issue with some virtual machine's stock PXE ROMs.

 * If connected to a Cisco switch make sure 'spanning-tree portfast' is enabled on the switch. Otherwise iPXE will fail establishing network connection.
