New ISP and router/no printer connectivity

Hi Everyone,
I have an ASUS Windows 10 laptop with an HP Photosmart C5180 All-in-One printer (scanner, copier). I have the HP connected to my network through an ethernet cable connected to my wireless router/modem. The system worked fine until I switched ISP's from AT&T to RCN. I unplugged the ethernet cable from the old router and plugged it into the new one. My laptop was showing a strong connection to the new RCN network and router. I checked the printer and it showed it was offline. I ran the WIN10 printer troubleshooter and it said my printer was unavailable to the network. I tried turning on and off the printer, rebooting the laptop, and restarting the router, all to no avail. I would appreciate any solutions, links, or ideas. Thanks

Sounds correct. For example.

If the new router uses a new IP range such as old was 192.x.x.x and the new is 10.x.x.x or such, the printer driver may not figure this out.

Also, you may have to reinstall the printer driver. Just grab the latest from and do it again.

Finally some routers BLOCK ACCESS FROM LAN TO WiFI. This one is a bit complicated and I did note it at but to disable this block varies with each model router.

Thanks for the response Rob! I believe the problem is the new router IP. It is a 10.xxxx, and the old one was a My problem is how to change the settings in WIN10. Can you help?

Your choice

Either change the LAN address range back or just go to to get their latest printer driver and reinstall. The later is how I fix this over and over.

HOWEVER if the issue is the BLOCKED ACCESS I NOTED, we have to configure the router to not do that.

Thanks again for the help Rob. I tried updating the software with no effect. I think because my HP is an older model, my options are limited. They offered an update to WIN10 (which I had already installed). I reinstalled the software suite which included all printer drivers, etc., but nothing changed. I checked the HP forums and it looks like my only option is to completely uninstall the printer and software and reinstall it (which I was trying to avoid). It appears the printer hardware and software has no way to recognize an ISP/router change without a complete reinstall! I appreciate your time and efforts.
