@ hamiro4457,
Whenever there is a possibility we always suggest our users to use the Almond with an Ethernet cable by setting it up as an Access point, which is nothing but hardwired Range Extender. In your case, you can do the same with out any concerns.
To setup the Almond in Access point mode: Connect the Ethernet cable to the Almond's WAN port and through the touch screen, enable the Access point, once the Almond is rebooted it would set itself as Access point.
