I have replaced the WiFi connector, but the 6515 doesn't know it's there. There are no WiFi settings to check in the communications area. This printer was printing okay with the previous ISP. When we changed ISP the tech redid the settings to the new network name, but at some point the WiFi disappeared from the menus. I bought another WiFi connector, but it doesn't change anything.
Recently we changed ISP to a new fiber optic provider.
My 6515 had functioned properly on the old wifi.
Since the change, it doesn't show "wifi" in the connectivity option.
I have purchased new and replaced the wifi connector with no change.
