I been facing a weird issue that I thought was windows or my printers (I have 2), suddenly they stopped working, they been working for at least 2 years and with this router for a year.

When I say stop working, means that even if the printer is showing on the router (with ip and even printer shows the ip), windows or android phone or ios phone cannot connect, If I delete the device, it nevers finds the device, like if is not connected (Both are WIFI).

I gave up and I started using Direct WIFI on one and USB cable on another one and share through network.

I recently found my previous router a Netgear, I connected both printers to this router, connected my computers (2 laptops and 1 desktop) and I was able to add both printers in the 3 computers and use it without any single issue. I am pretty sure this happen with one of the firmware update since this issue is only been a couple of months.

Printers are  HP Deskjett 2600 and Cannon TS6020

I tried to use address reservation, disabled SPI Firewall and nothing worked.

Any help would be appreciated.

Thanks
