Hi patel27,

The printer requires a 2.4 GHz broadcast that uses WPA2 encryption.

Please confirm your network meets these requirements. You have a dedicated 2.4 GHz broadcast that uses this encryption standard, and that you can see it broadcasting on another device. <<<<

The wireless network interface in your printer is not user replaceable.

No. Nobody on here can tell you how to "replace the WiFi card," because no employee at Canon USA would have told you to change any component in your printer.

Call Canon support for help. Our number is 1-800-652-2666.

No one in Canon support is trained on replacement of these parts. Although you think you were talking to Canon, you were probably talking to some third party trying to scam you. We never advise customers to try to do their own repairs like this. Normal troubleshooting for this issue would be; restarting your Wi-Fi router, computer and printer and retesting. If unsuccessful, moving the printer closer to your Wi-Fi router could help. If still not resolved, uninstalling and re-installing the printer drivers would be the next troubleshooting step.

If whoever you spoke to didn't mention any of these things, you were not speaking with anyone from Canon.

Mike:

Thanks. Is there any assembly drawing for MF452DW? where to look for online!

I tried everything to connect wireless and with wired, still no luck. When I try wireless or even wired, keep searching for network available, keep going curser round and round, nothing happening.

If you can provide your contact number, I can call after 4:30 pm Houston time or I have coming Friday off, can call you. Mike it will be a great help. Printer was working fine with my Lenovo laptop and Iphones, but now no more. I have not done anything, it just not communication. I tried 2.4Ghz no luck.

Let me get this straight! Do we need a network that does only 2.4G and not both 5G and 2.4G to bring this printer to the network? I have a problem with the M451dw where it keeps dropping off the network. Currently it is connected to a network that supports both 2.4 and 5.

Thank you.

Techy,

Although off topic, I'm happy to clarify. The printer has a 2.4Ghz radio. It can only see and communicate with a 2.4Ghz wireless network. Many router manufacturers use a single SSID name for all broadcasts (dual and tri-band routers) 2.4, 5, 6 and 7G. The number of bands your router supports depends on brand. Sometimes devices can have issues connection to a multi-band router that is using thr same SSID name for all broadcasts. In these cases, you can use one of the following options.

Give each network a unique name. Example mynetwork2.4, mynetwork5G, mynetwork6G. Another option is to temporarily disable the other broadcasts while connecting the printer, then turn them back on. This is not always needed but can help if you are troubleshooting a connectivity issue.
