MoCA network management device and a method for channel allocation to nodes over a coaxial cable in a MoCA network, comprising the steps of detecting a connection attempt from a first node on one channel out of a list of channels; and selectively allowing connection to said channel based on a likelihood parameter (R) which is dependent on which channel in the list of channels the connection attempt is made on. The list of channels may be a scan sequence of channels, wherein the likelihood parameter is dependent on position in of the channel in that scan sequence. If a node is denied access, it may switch to a next channel in the scan sequence.
