1. A Multicast Listener Discovery (MLD) device comprising:
a memory storage; and
a processing unit coupled to the memory storage, wherein the processing unit is operative to:
establish a first channel of a first radio link and a second channel of a second radio link with a second Access Point (AP);
detect interference on the first channel of the first radio link with the second AP:
check availability of a redundant radio at the second AP;
establish a new radio link with the redundant radio at the second AP wherein establishing the new radio link with the redundant radio at the second AP comprises detaching a Media Access Control (MAC) Service Access Point (SAP) from the first channel;
reroute data traffic over the new radio link to the second AP;
after establishing the new radio link, sever the first channel with the second AP; and
change the first channel and reattach the MAC SAP across the first radio link and the new radio link over the redundant radio.
