I have been trying to improve WiFi coverage from my BT Smart Hub in my next door office into the rest of the house. While I am happy to receive 60Mbps in my office it drops to just 3 at best in the lounge. I have bought three Tp-Links to try and improve reception with no effect whatever - presumably because the signal has to penetrate what is in effect an outside wall. Today however I have run 10m of ethernet cable from my office router round through to the lounge connecting up to the model as above and another which I have, WA860RE which has two antenna. Sadly again there is no improvement whatsoever. If I plug my laptop into the end I am definitely getting 60Mbps, so why can't I still get a decent signal from your products?
