I just got a new Canon TS 3420. I’m having a very frustrating problem. I can’t get a consistent Wi-Fi connection. I get an intermittent strong signal but usually I have a very weak signal and my computer tells me that the printer is offline. The printer is sitting right next to my router. I can connect all my other devices to the router including my tv, which streams content without a problem. Canon even sent me a replacement but it’s still the same. Canon blames my router and my internet service provider blames the printer and I’m stuck in the middle. Help!
