1. A method of measuring performance of a first communication channel at a first access point in a wireless local area network (WLAN), in which the first access point is associated to a client device so that the first access point can send data to, or receive data from, the client device on a second communication channel, the method comprising:
switching a proxy working channel of a proxy access point to the first communication channel;
making one or more proxy performance measurements of the first communication channel at the proxy access point after switching the proxy working channel to the first communication channel;
disassociating the first access point from the client device and associating a second access point to the client device;
switching a working channel of the first access point from the second communication channel to the first communication channel after disassociating the first access point from the client device; and
making one or more performance measurements in respect of the first communication channel at the first access point.
