I got the same problem (see some posts under you)! It only helps to restart the routher with the tether app.

TP-Link told me the router does not support airprint. But it did! It went out of service with an update in 2013 - before there were no problems - the printer was always connected.

So if Canon says this is a dual band router problem - does it mean that it will work when I deactivate the second band (5Ghz)?

Hi - I'm not sure about deactivating the 5Ghz Band. I don't know how to do that. This is the info Canon sent me: Further to our telephone conversation we are sending you the instructions the set a static IP address on your printer.

Please open IJ network Tool. You will find if via Start, All programs, Canon Utilities.

Once the IJ network tool has found your printer make certain that it is highlighted and select the Configuration Button. In the next screen you will see the option to select Use next IP address. You can leave it at the suggested IP address. Select OK and now your wifi connection should be a lot more stable.

This suggestion did not help me but maybe it will you.::) TM

Update the latest firmware in 2014. By the way, TD-W8980 belongs to ADSL...

Hi - thank you. Guess that's why I couldn't find the model number under Dual Band Routers. TM

Thank you for your response.
We did not opt to install any additional software (and the ping idea may work too) because we felt the Dell hardware should not require this.Their other printers work as expected without software broadcasting on the LAN to keep the NIC alive.This would be okay on a small home network but not what we've opted to do on our corporate LAN.Thanks again!
