Cons: After 1 month, wireless disconnects sometimes multiple times per day. Had this problem with initial purchase. Replaced via RMA and replacement had exhibited exactly same problem (fine for 1 month, then continuous disconnects).
Pros: Signal goes where other routers haven't. I like the guest network feature so visitors can go online but not get on my home network.
Cons: Only worked for 8 months. No internet. The radio still works, I can connect to the router but it does not connect to the internet. The internet light is out. It was treated well, it was not dropped or even used for shocking content. The d-link site does not seem to have a link for warranty claims.
Summary: When it works, download speed is good. However, I have to re-start it every two or three days because it drops the internet connection. I contacted D-Link by email and they told me to re-configure it. I did, twice, and it still behaves the same way. They provided further contact information to facilitate return but I'm sorry I bought it. I just don't need to waste my time this way.
Cons: Most of my wireless devices wouldn't stay connected to this router and would have to be reconnected each time I wanted to use them. This included both of my Tivo Premiers, my Samsung BluRay player, my DroidX. Also, under heavy load such as when transferring a movie from my media PC to one of the Tivos, it would stop working and had to be rebooted. I switched back to my trusty old NetGear router which has always worked perfectly and NEVER needed rebooted.
Summary: Depois de muita pesquisa optei pelo DIR 645 que por incrível que pareça, ninguém da D-LINK sabe configurá-lo com as funções que o produto oferece.... Depois de 2hs de suporte, o aparelho parou de funcionar, e pedem para que eu o envie arcando com os custos. Não recomendo, tecnologia de sinal fraca a presença de barreiras.....
Summary: Gutes Featureset, aber sehr unübersichliches Setup-Interface. Die versprochene erhebliche Verbesserung der Verbindungsqualität wurde hier im Altbau mit teilweise Rigips-Wänden und 20-30 anderen schwachen WLANs garnicht eingelöst. Direkter Vergleich wegen anderer Platzierung des Vorgängerrouter (Fritzbox 7170) nicht möglich, mit dem DIR-645 zwar sehr gut Empfang mit Laptop im gleichen Raum, dafür in der 6 Flurmeter entfernten Küchen äußerst schwach und beim Nachbarn im...
