So I recently bough a new router: Tenda N300

I'm very please of it, except : form time to time the connection drops. The weird thing is have more connected devices and the internet drop for only some of them. While some work perfectly and can access 192.168.0.1 (router) then other even if I restart them or plug-unplug the cable, they won't connect to router and cannot even access 192.168.0.1 (the router). The connection looks limited, so is like the router is blocking them.

Why does this happen and how can I fix it?
