Then I had to set it up. The technical aspects were easy. But where to put it? Too close to the router and it would not reach the bedroom. Too far away and it would not work. I tried it in the landing. That was too far from the bedroom. Then in the only socket in, what to call it, the vestibule? But that was too far away from the router. Hmm. This was a precision job. I decided I had best try it in the corner of said vestibule closest to the router. But that required an extension lead! But if that's what it takes, that's what I'll use. So I dug one out, installed the extender, and checked how it worked. And it did! Lovely wifi in bedroom and conservatory. I have not yet tried how far into the garden it reaches. But I'm chuffed! I should now be able to do all my video calling from at least the entire house!
Not pretty, but effective; the wifi extender
