Both 2.4 GHz and 5 GHz wireless networks are active. There are no settings excluding the printer I can find. The router is 12 inches from the printer so interference isn't an issue and it worked fine until I upgraded the router firmware yesterday.</P> Tue, 16 Jun 2020 21:10:23 GMT souprgrover 2020-06-16T21:10:23Z https://community.usa.canon.com/t5/Printer-Software-Networking/Updated-ASUS-router-firmware-and-now-my-canon-MF726CDW-can-t-see/m-p/310292#M4518 <P>I recently had to update the firmware for my ASUS AC2400 dual band router. After I updated it, my Canon Imageclass MF726CDW printer can no longer see either the 2.4 or 5G wireless networks. It can see a third network from xfinity, but all my computers and phones do not connect to that network so I need the printer to connect to the ASUS network. I have rebooted the router and the printer. The printer firmware is up to date.</P> Tue, 16 Jun 2020 18:22:15 GMT https://community.usa.canon.com/t5/Printer-Software-Networking/Updated-ASUS-router-firmware-and-now-my-canon-MF726CDW-can-t-see/m-p/310292#M4518 souprgrover 2020-06-16T18:22:15Z https://community.usa.canon.com/t5/Printer-Software-Networking/Updated-ASUS-router-firmware-and-now-my-canon-MF726CDW-can-t-see/m-p/310299#M4519 <P>Hi souprgrover.</P><P>&nbsp;</P><P>Make sure the router is broadcasting its identity.&nbsp; If the router is not broadcasting, then the printer will not register it as present even if it does facilitate communication between devices.&nbsp; Also double-check that no settings on the router are excluding the printer, and that the 2.4 GHz connection has not been disabled.</P><P>&nbsp;</P><P>Did this answer your question?

I turned off the firewall and was able to reconnect the printer then turn the firewall back on. I also set a static IP for the printer.</P> Tue, 16 Jun 2020 21:32:58 GMT https://community.usa.canon.com/t5/Printer-Software-Networking/Updated-ASUS-router-firmware-and-now-my-canon-MF726CDW-can-t-see/m-p/310309#M4521 souprgrover 2020-06-16T21:32:58Z
