AC1200 extender
I just bought this to try and boost my signal strength in my house, Setting up was a pain (I hate using mobile phones but it was my only option), the phone could not see the device and the "instructions" were less than useful. Eventually I pushed the reset button and finally the phone could see it. Finally got it working but it barely made any difference to the signal strength in the house, my laptop still keeps switching to the 2.4 ghz signal because the 5 ghz is still too weak! I'll probably return and get a refund as it's not doing what the box says, i.e. "kills dead zones".
I might as well try one of the cheapies off ebay, at half the price, it couldn't be any worse! Oh, and it doesn't even have to go through brick walls, just two gyprock walls! Pathetic.
