Wireless Mesh Network (WMN) is one of the important elements in the future networks as it has the ability to provide high bandwidth wireless backbone which covers a wide physical region. In general single radio mesh nodes operates on a single channel and it suffers from capacity concern. Hence it is necessary to provide mesh routers with multiple radios using multiple non overlapping channels. But, multi radio WMN suffer from link failures caused by interference of the channel, dynamic obstacles, and applications bandwidth demands during their lifetime. In this paper exhaustive analysis of various reconfiguration techniques is presented which is used to recover wireless mesh network from link failures and the issues to be addressed in order to maximize the network performance. A reconfiguration scheme utilizes primitive link changes such as channel, route switch operations and radio to recover WMNs from link failures. Generally, reconfiguration schemes produce a set of reconfiguration plans and opt for the best plan according to the desired criteria which is required for that particular. Based on this best reconfiguration plan the system reconfigures network settings among all mesh routers and thus make progress from link failure
