Solved my problem at a stroke,
Verified Purchase(What is this?)
This review is from: TP-LINK TL-WA830RE 300Mbps Wireless N Range Extender (Accessory)
Until I got this, I was constantly plagued by signal drop-out only a couple of rooms away from my wireless router, let alone on the next floor up, let alone in the loft!
This has solved everything at a stroke and I give it my strongest recommendation.
