this is a switch/wireless/router

So you will still have to use the tt unit :P

I've gone for one. Reviews look pretty good on the whole. And for £17 delivered it seems like a bargain.

I've got the original SuperHub. I was thinking of paying to get a newer VM issue one. This is of interest to me only because of the concurrent 2.4 and 5Ghz (which you already have) and external antennas which should increase range and signal strength.

You may want something with a higher Antenna Gain because the 1.5dBi won't go far for the 5Ghz because I think the signal drop-off is considerably more than 2.5GHz.. If you have lots of devices then the cheaper units can suffer under load and even more so if they only have 100Mbps LAN port if transferring between devices.

I've heard good reviews about the TP-LINK Archer C9/D9 (Ones for Cable and the other is for ADSL) :-
£95 for the D9 : http://www.amazon.co.uk/TP-LINK-D9-efficient-connection-increased/dp/B00LCSOLX6
£90 for the C9 : http://www.amazon.co.uk/TP-LINK-C9-Wireless-Beamforming-Efficient/dp/B00PK0JLCI

But I guess it will really depend on what kind of reliability, range, amount of devices and type of use you are going to want. This edimax unit will probably be ideal for a few devices in a small house.

These are fine for locations with no other radio interference / access points but if you want the best range / signal quality the ASUS units are hard to beat. Good radio design and excellent firmware / custom firmware. Worth running a site survey using Wifi Analyser (free on play store) to see if you have other APs in range. Also worth locating your AP near the centre of the house flat for optimal range. Consider the first floor not near the front of the house where the cable comes in from the road. Also remove any Wifi Repeaters (these halve your bandwidth) unless you use 5gHz as back haul and 2.4gHz for clients - best to run cable or mains networking if you need to extend the range. I had 3 APs (dual external ant) replaced with a single ASUS unit. Never looked back. If you are paying for high speed internet remember the units supplied by Virgin . BT / Sky cannot really deliver that speed to your devices. Best to build out your own network at home and use the ISP device as a gateway to the internet and disable the WIFI etc. With Virgin the Superhub is pants, put it into Modem mode and connect to a quality AP I got faster throughput and way better WIFI. BT Home hub is better than a VM Superhub but still cannot hold a candle to a 2 year old ASUS model!
