Summary: I always bought a D-Link router since needing one because it always worked well and it was easy to install BUT I won't ever again purchase another D-Link. First of all my last D-Link router lasted less than 6 months. It was great while it lasted. I have tried 3 days to get this one to work. I am so disappointed and frustrated. I wouldn't recommend D-Link Dir-857 Dualband HD 900 Mbps 4-Port Gigabit Wireless N Router(DIR-857)to anybody in good conscience.
Don't like this router, going to get rid of it and go back to Linksys

Summary: Hard to set up, keeps dropping the signal on the 2.4 ghz band. Have to reboot the router to get it working again. This happens several times a week. Tech support was not able to cure the problem. Read a review on Cnet that recommended it but it has not lived up to their recommendation.
Summary: Comprei esse roteador para a empresa e no início foi bom. Acabei comprando para minha residência também. Após um ano de uso, ambos começaram a apresentar problemas de não passar adiante a velocidade de banda que chegava no cabo do modem. Coisa absurda, eu media a velocidade no cabo do modem antes do roteador e marcava 10Mb, quando eu conectava o cabo no roteador e media por ele, estava transmitindo wireless a menos de 0,5 Mb isso estando do lado do computador.
