DHCP Server giving out incorrect IP addresses
« on: January 18, 2015, 06:38:58 pm »
This has happened to me twice now.  I have switched the ip range my Almond+ from 192.168.81.xxx to 192.168.13.xxx.  99% of the time the computers get the correct IP addresses, but twice now the computers start getting IP addresses that start with 192.168.81 and I have to wait until the DHCP leases expire before the Almond+ sends out new (correct ones)

Hi there....

Well we know the issue, we are going to fix it in future firmware. This issue is only coming from wired connection, you can release/renew the ip from wired client.
Use following commands on your client:-
For windows:- Open cmd then type --- >ipconfig/release>ipconfig/renew

For Linux:-
dhclient -r interface
Where interface is the device you want to get a new address for.
like dhclient -r eth0.
or
/etc/init.d/networking restart
or
ifdown eth0; ifup eth0
or
If you're using the dhcpcd tool then:
dhcpcd -k interface
dhcpcd interface

or you can do one thing after changing LAN segment, reboot your almond +, it will fix the issue.

Thank you for chiming in, but my issue seems a little different.  My issue is on both wired and wireless connections.  If I manually type in an IP address, everything works fine, but DHCP is sending out incorrect addresses to all clients, and it doesn't seem to even report it is on and/or giving out addresses.  I've tried restarting the DHCP server, restarting the router, releasing and renewing the IP address on a windows and OSX client, updated the router to the beta firmware, left the router unplugged for a minute, restarted the modem, and left everything alone over night to see if it would start giving out correct addresses in the morning.  Still not working though.  I also tried changing the DHCP server to go up to 151 to force a change and hope it would reload the DHCP server again.  I'm including some screenshots to show what I'm talking about.

Edit:  Also, all my static leased ip address computers lost their correct addresses too.  This is very annoying and inconvenient since I have to manually set each one now to get it online

This topic can be closed as I was able to resolve this.  It was because of another DHCP server getting turned on
