CANON TR7520 - Changed router now I cannot change password on printer (does not connect)

[papirico]

Hi, 

I just changed my home router and now the printer does not want to connect. It can see the SSID, when selected throws an error message "Failed to Connect" but it never asked me for the password. 

My router does not have WPS (as far I can tell). 

Thanks,

Greetings,

Re-run the set up / installation software.  This is required to change the wireless SSID or password.

These steps are for a different model, but are identical for the 7520.

Hey Shadowsports, 

Thank you so much, using the Setup app from the laptop fixed the problem.

This drove me crazy on my TR7520 until I did this. Set up LAN settings - use manual setting, and when the wireless network shows up, go to enter it manually even though your network shows up in the list. In other words, DON'T click on your network name, type it in manually. Only then did the setup procedure allow me to enter a passphrase. Until that, it simply went to "connecting to network" without allowing me to enter a passphrase. After that, everything was straightforward. Hope this helps.
