A method for condition monitoring of a wireless network in an industrial plant, wherein the wireless network comprises two or more wired gateways (10a, 10b) and a plurality of access nodes (15a, 15b,...) connected wirelessly with at least one wired gateway, wherein each access node is associated with at least one field device (20a, 20b,...), wherein the method is implemented with an industrial device connected with the two or more wired gateways (10a, 10b), the method comprising: periodically receiving information associated with packet transfer, channel access, and communication links from one or more of each access node and each wired gateway; estimating from the received information one or more parameters associated with each access node, wherein the one or more parameters are estimated based on one or more of: a number of packets transmitted from the access node to the corresponding gateway, and a corresponding number of responses received from the corresponding gateway; a number of packets transmitted from the gateway to the access node, and a corresponding number of responses received from the access node; wireless communication channels used by the access node and one of a neighboring access node and the corresponding gateway; a number of access nodes (15a, 15b,...) and wired gateways (10a, 10b) connected with the access node, and identity of the corresponding access nodes (15a, 15b,...) and wired gateways (10a, 10b); and a data traffic of the access node; determining a connectivity status of the field devices (20a, 20b,...), based on the one or more parameters estimated for each access node (15a, 15b,...), wherein determining the connectivity status of a field device comprises comparing a rate of packet transfer for each access node (15a, 15b,...) associated with the field device with a threshold value, wherein the rate of packet transfer is one of the one or more estimated parameters and is a ratio of one of the number of packets transmitted from the access node (15a, 15b,...) to the corresponding gateway, and the corresponding number of responses received from the corresponding gateway; and the number of packets transmitted from the corresponding gateway to the access node (15a, 15b,...), and the corresponding number of responses received from the access node (15a, 15b,...); and rendering the connectivity status of the field devices (20a, 20b,...) on a user interface associated with the industrial device. periodically receiving information associated with packet transfer, channel access, and communication links from one or more of each access node and each wired gateway;
