I have a deco m5 system. I need to connect my printer up to the network with an ethernet cable connected to an access point other than one of the m5s (the printer location does not suit an m5). 

Please can anyone recommend a device they use in a similar situation (I want to avoid forking out for another m5 just for this). 

I've been pulling my hair out trying to get other devices I own (including some tp-link ones) to work stably with the M5 as a wireless access point for the printer. So a recommendation that works would be appreciated.
