Wireless printing

[purbrookian]

Since changing my internett provider,  neither of my printers will communicate with the computers.

How can I check wireless connectivity?  iMac OSX Yosemite, Canon MG5420

Do you have the same Router or did you get a new one from the ISP?

That may be the cause of the issue.

Thanks West...problem solved ; had to reconfigure both printers to match the new equipment, as you suggested.

Appreciate your input.
