I currently use this router and also use last 18 months . specification of this router is that power of wireless is so high . not more cost for purchasing this router . but there is a problem sometimes it not connect with my laptop and mobile and say run diagnosis’s and many more. but recommended that if you want to purchase router than its ok no problem . its allowed more than one device to connect as like other router and do block some one ip address if you want and also use mac filtering for which device you want to allow.
