I just bought a Canon MG3550 for Wireless use. I have been struggling the past few days with getting a stable connection from it to our apartment wireless. What I have found out so far is that the problem seems to occur when the printer has gone to sleep or been turned off for some time. Whenever it is turned on again it's status will show "Offline", and not respond. However this only occurs (I think) when it is the last (or after others) devices to connect to our router after it has been off/sleep. I have tested this by turning Wifi off on all other devices in the apartment (Phones,Tablets,Laptop). In this case it will connect after being manually turned on, and even wake up from sleep when it is asked to print. I checked this by turning everything off, including router. Re-connected the router, then Printer, then my main work laptop. From then on I could print, turn off/on printer and on/off my main laptop, and there would be a stable connection. Then I turned other devices on everything STILL worked as it should. Then when turning off the printer with other devices ALSO connected, the printer would only show "Offline" when attempting to print.

So thinking this was a minor IP communication error I assigned the printer a static IP outside the DHCP pool, which I thought would fix the problem. It didn't.

Whenever it is online and working i print out the Connection information everything checks out fine, It has the right SSID, 70%+ signal strength, Assigned the correct static IP I gave it, even has an IPv6..etc..(This i disabled, just now thinking it would make a difference. Is IPv6 really neccessary?)

However, when it is shown as Offline, the Connection Information still checks out like before, (correct SSID) but it is missing where it should state it's IPv4, IPv4 Default Gateway, Subnet Mask, IPv6, IPv6 Default Gateway, Subnet Prefix Length <---They are all blank on the paper.

Please any help? I I bought it specifcally for it's wireless function, so this has been frustrating me the last few days.

I have a Belkin N750 DB Wireless Dual-Band N+ Router

For some reason after turning off the IPv6 function on the printer, it has been online and working since yesterday. I don't know why IPv6 changed anything connection-wise or if it's just a coincidence. Just simply checked it off. I don't really know what implications disabling the Printers IPv6 functions are, maybe someone here could shine some light in it for others with the same problem.
