officejet all in one 8620 and M252 laser jet not connecting to Wifi. They used to connect fine. Now they say printer offline or printing error, and I cannot use my phone to wifi print either.
Tried wifi wizard on the 8620 and it sees the network but after I enter password it won't connect.
Tried downloading driver, downloading software and connecting my M252 with USB cable, and it does not find my wifi settings.
In my wifi connections on laptop I can see both printers and my wifi name.
Downloaded troubleshooting software but it does not recognize my wifi.
Tried removing the Officejet 8620 and re-adding but it will not recognize wifi.
Tried pushing the WPS button on my router to connect Officejet 8620. Nothing seems to work.
Any ideas would be appreciated.
