I'm on stock 4.4.0 as 4.4.1 hasn't yet arrived to my place.
I've no idea how Network Monitor Mini calculates its speed, let's say it's up to 14'000'000 bytes per second which makes it 112Mbit/sec which is a lot lower than the theoretical maximum of 150Mbit/sec, so I'm not lying.
BTW, I've discovered that pulling data at this rate makes the top of my phone significantly warm (almost hot) - I've no idea why since last time I checked WiFi has a very low power consumption.
Anyway, my phone has cooled off and I've just copied 8gigs of data without reboots. Next time I will just make sure that it's sufficiently cooled before doing that again.
