It says that I have two 8610's, one at the old IP address that is says is installed, and one at the new IP address that is says is not installed. I tried running the HP Print and Scan Doctor 5.3. The just-installed printer disappears from the Printer & scanners control panel, and the Scanner device never gets installed. I have connectivity - I can browse to the printer's IP address and get the control panel, but when I try running the HP printer driver, it sees the printer and when I click to install, it quickly installs the printer (I can see it on the Printers & scanners control panel), but then seems to hang for several minutes, then comes back to a page saying 'Unsuccessful Network Installation'. I reconfigured my OfficeJet printer to use the new wireless network so that it's on the same subnet with the PC and I am trying to reinstall the printer on the PC. This has caused all of my IP addresses to change - it was 192.168.1.x and now it's 192.168.86.x. I recently installed a Google Nest WiFi router.
