Very bad qaulity router , dont use Supersonic.

Please do not waste your time and effort with Supersonic , there wifi routers is the cheapest they can find and the installer plugs it is and you are left to your own mercy. We have used 3 internet providers before and the wifi signal was very strong and anywhere in the house we could use devices , we now are using Supersonic and the devices only works when you are next to the router , when we contacted the installers , he just said that it is not his department and he will let them phone us , which still have not happened and also he said we must buy wifi boosters , which we never had to use before , apparently we will now be needing 2 or 3 of them. We will be looking for another service provider as soon as possible.
