Unable to reserve an IP address on Hub 5

Hi,

I have a couple of devices which I'd like to use a static IP address.

I went to the DHCP page and added a rule for one but when I went to reserve the second I get an error...

"Sorry! There was an error while updating your settings. Please try again a bit later".

I have tried a bit later and also switched the Hub off for a while but I still get the same error. I tried phone support but that was a joke. The chap at the other end clearly had no idea what I was talking about and his advice was to try later.

I know I can apply a static IP individually to my device within it's own settings but I'd would prefer to do it this way for future use.

 

Any ideas?

Thanks

    Hmm, I’ve lots of Reserved IP’s in use, as well as a few static ones.  Don’t use a VM router though, but I wouldn’t recommend one way against the other as far as IP issuing.  I also keep my DHCP scope as small as possible.

    You are on the right path and I really don't recommend static addresses for residential users. The DHCP reservation range is 192.168.0.10 to 192.168.0.245, and you should reserve your IP address within this range. By reserving an IP address within the hub's settings, you centralise your network management. The hub's DHCP server is smart enough to 'earmark' these addresses, so it won't dynamically assign them to other devices and cause a conflict.

    Let's say your devices have dynamic addresses of 192.168.0.11 and 192.168.0.12, and this is the easiest way to proceed. You find the MAC addresses and enter the MAC address and 192.168.0.11 for the first device and click Add rule. This should work and you do the same for the other device with its MAC address and 192.168.0.12.

    The most reliable way to get your devices reconnected is to turn them off, switch the hub off at the wall socket, wait two minutes and switch back on. Once the hub has fully rebooted (takes some minutes to get a solid white light), switch the devices back on and they will be forced to send a "DHCP Request". The hub will respond with the newly reserved IP addresses.

    It is much better to set the Static IPs on each of the devices
     i.e. via the device's settings screen or web management page.

    Use the IP range 192.168.0.2 to 192.168.0.9 - extend this if needed by moving the DHCP start point to say 192.168.0.30

    Using a  "Reserved IP" is not quite the same as the devices remain dependent on the VM Hub's DHCP server working correctly.  

    Also when the VM Hub is Factory Reset or replaced all Reserved IPs are lost.

    Are the reserved IP's inside the DHCP scope?
