Hi, thanks for posting question here.

Based on DHCP, MER is similar to Dynamic IP. Difference is that there is a special field called option 61 in the DHCP packet. This option is used by DHCP clients to specify their unique identifier.  DHCP servers use this value to index their database of address bindings.  This value is expected to be unique for all clients in an administrative domain.

If you purchased this wireless router recently, it is suggested to contact the retailer to return it, as SKY has restriction on third-party router/modem.
