We live in an old cottage, wifi difficult to get through thick walls. I wanted a wifi extender to improve connectivity to a computer further down the hall which is too far away for ethernet cabling. Didn't want an expensive gadget, just a usb extender. This little gadget has worked very well. A little difficult to set up but once set up connectivity has been super. good speed and wifi not dropping out. Would definitely recommend this usb wifi extender.
