I have (among other network devices) a RPi
Linux rpi2 4.1.10+ #821 PREEMPT Sat Oct 10 00:12:23 BST 2015 armv6l GNU/Linux
It is connected via WiFi to an access point (like the other devices). A static network configuration works (connection to the AP and TCP/IP traffic).
I now wanted to move it to DHCP by modifying in
wlan0 stanza from
auto wlan0 iface wlan0 inet static address 10.10.10.5 netmask 255.255.255.0 gateway 10.10.10.254 wpa-essid "MYSSID" wpa-psk "mypassword"
auto wlan0 iface wlan0 inet dhcp wpa-essid "MYSSID" wpa-psk "mypassword"
The interface connects to the AP (which is visible though
iwconfig) but does not get any IP.
- No request is visible on the server (which runs
dnsmasqso I can se all the logs - which include the ones from other devices).
- other devices on the same AP get addresses without problems
tcpdumpdoes not show any DHCP requests
What could block the RPi to request an IP address?
Answer (summarizing the answer to the question and my further comments): the lack of a client (which I must have removed when reconfiguring the device many times). Installing
isc-dhcp-client fixed the issue.
