I have also posted this on plusnet's forum but so far nothing, hopefully I can get more help here
I got a nice shiny Hub One and everything is fine apart from transfers over the 5Ghz network.
I can't get anymore than around 14MB/s (120Mbps ish?) which is way below what it should be capable of.
I have confirmed it is using 5Ghz as I disabled 2.4Ghz just to be sure, I also made sure no other access points in the area, I checked its set at the highest rate (1300Mbps) and the card in the machine is capable of 867Mbps. (Network status on the machine shows it is actually connected at 867Mbps)
Copying from one machine to another seems to produce a slow rate, one machine is on the gigabit wired and confirmed to be running at gigabit as I get at least 100MB/s if I use wire to both machines.
The only thing I have noticed when I am copying is there is a very high pitched squeal coming from the router which goes after the transfer completes, is it broken and need replacing already ?
