Can anyone tell me if by installing a tp link extender will contribute towards now continuous no air printer found

This is getting very frustrating. With the ipad4 if I turn off the printer, the iPad and the router it resets and works for a few hours. The iPad seems to be suffering more. The two iPhones a4S and a 5 work okay.

This does seem to have developed since installing the tp link to provide the wifi connection to a you view box.

With the utmost respect I do not want someone advising me to download standard problem links I need someone who has experienced this and found a way out or someone knowledgable to comment.

Cheers
