This is driving me mad. After a recent power cut, my printer decided it wasn't going to print wirelessly from a hard wired W10 desk top. Reconnected it to wifi network, couldn't reach it. Oh well, connect via ethernet, reset, assign static ip, all good, prints from W10 desk top and entering the printers setting page enables me to set the ip in the printer as well. So far so good. Next, turn on wireless, nice strong blue light, printer happily connected to the network, can be seen from phones ipads etc. But not from the desk top pc, when you enter the IP of the printer into a browser, it can't find it, trying to print tells me that the printer is offline. Deleted and added printer, all to no avail. Current situation is that I must manually switch the MX520 for wireless LAN if I weantr to rpint for ipad etc, and then manually selected wired LAN to print from the desk top. Am I a) being stupid, b) missing something or c) in need of a new printer.
