Can't print from ethernet printer connected to Archer A9 unless I power off DSL modem
Recently replaced old router with Archer A9, but have had recurring problems with ethernet connected printer. I finally figured out that if I turned off my DSL modem, then the printer would print. If I leave the modem on, my Xerox Phaser 6180 goes to offline status and won't print. Why is this happening? And what can I do to fix it?
