Great news. I didn't need to mount it in the attic, just stuck it up on the ceiling halfway down the hallway, one access point does the whole house, even when I go to the far edge into the sunroom, though it says -96dbm on the wifi signal meter, I'm still getting a stable solid 234mbps on the 5ghz ac radio.
The only thing that's driving me insane is all the options, there's just too much to tinker with. Is there a nice manual for this thing anywhere? I think I'll make an exception to RTFM with this new old toy
I might get lucky with a 3802 soon so might swap this one out, but this does everything we need and I like the blue light on it, I thought it was going to stay green, but now it's blue.
I used a shielded super-stiff cable to power it, crimped it all nice and good but then realised that the cable has a poor bend radius so at the moment one can see a little black wire looping out, only just mind you... I think I'll drill an extra hole through the mounting plate and then just swing the cable down so it pops right in at a squeeze.
All in all, quite happy with it, just the plethora of options go over me tiny head which has most definitely been spoilt by simplistic consumer wifi access points.
