reserved IP address has no effect

Recently swithed to Sky, Sky Hub (SR123) working. 

 

I need to have fixed IP address for one of my devices serving as a home server. In the router web interface UI, I go to

"Connected Devices > Devices"  and clicked "Edit" on the target device, clicked "Reserved IP" and "Save"

After saving, the Device List still shows the device as "DHCP" in the "DHCP/Reserved IP" column.

And if I click "Edit" again, I can see it is still "DHCP" configuration, as if the saving has no effect.

 

What did I do wrong? 

 

P.S. I cannot set DHCP settings using the Sky App, and what's even worse/weird, Sky App connected devices shows every device as a different ip address 192.168.0.x, instead of 192.168.1.x that I set via the Web interface

@newway the web interface on the SR213 Sky Max hub has very limited use. Most of the settings have limited use with the customer settings being moved to the My Sky app..

 

By default Sky always use the internal address range of 192.268.0.1 to 192.168.254 with a sunbnet mask of 255.255.255.0 the DHCP server on my unit and I presume yours allocates address  from 192.168.0.2 to 192.168.0.100. The hub' gateway address is 192,168.0.1


Have you edited this screen ti switch the range to 192.168.1.x? If you did the greyed out DHCP range details change?

By far the easiest method of having a fixed IP address is to assign the device an address such as 192.168.0.200 ie outside the range of the DHCP server. Personally I would nit try to changecthe internal address range unless it is vital.

@Chrisee Did you not change your ending address to 192.168.0.100. previously? Mine is set to 192.168.0.253.

@Me134 it is possible I did. @newway limiting the DHCP range and assigning fixed IP addresses is an option the will work.

I have changed the LAN IP range, below

 I suspect the Sky APP somehow is not realtime refreshed and it is showing my old up range. I did try manually assign an IP outside of this DHCP range e.g 192.168.1.200 in the reserved ip field, but a pop up come up said something like "this ip is out of dhcp range"

 

interestingly, I tried and the reserved ip works on my iPhone connected via WiFi, but I highly doubt this limits to WiFi devices but not LAN devices
