Hi.
I have a problem with my DIR-825 R2 router. Specifically with a printer that I connect via a USB cable. The router can see the printer (Brother DCP-385C), I can easily install it in the system, but every 30 seconds or so, the router restarts the printer as if it was cutting off the power. It's just that everything on the printer goes blank and restarts. Firmware 1.0.6, checked on two identical routers. What's the problem? (google translate
