Almost perfect. Paired to my Sky hub I assume ok but when I took it to the offending dead zone we picked up the new wi if as a new connection called TP-Link...... When I tried to connect it asked for a password. Sky one didn't work so I called the help desk: got through in a couple of mins and she was very helpful. They told me that the pass number was on the plug itself (facing the wall....). So I disconnected and unplugged and wrote down the pass number and Bingo!! A full bar of wi fi. My daughter will be so pleased. This would appear to be the answer to our wi if woes so a small price to pay.
Got this for our flat as it seemed ideal - no wires - good range. It arrived on time but what a nightmare!! Range was under 2 metres and then it kept going off all the time - over and over again at random. Returned immediately.
