Pros: Great reliability and performance. Using both bands 2.4 & 5 GHz the 2.4 for regular laptops, etc and the 5GHz and the 4 1-GHz ports switch for multimedia without any anomalies to report. Using CyberPower UPS for the network switches, router, and a SpeedStream 5100 DSL modem.
Cons: None really (the blue LEDs are a bit bright but some opaque tape solved that).
Summary: I bought this item used and I am going to call my ISO to see why I am sometimes getting internet offline notices or it is taking a long time to download a site I click on since I have the highest broadband internet connection.
Summary: This is a decent router for the price you can get it for on Ebay. It's an economical way to venture into the dual channel arena without spending a great deal of money. If the 2.4Ghz band is all full with your neighbors' access points... you might want to give 5.8 Ghz a try. Chances are there will be much less if any interference in the higher band, since most people are still using 2.4 GHz.
Summary: Great router very easy to install GREAT FOR GAMING!!! Very good feature for the price, I cannot say how much I love this router. DLink's QoS feature actually lives up to the claims, I am very very happy. Router is currently running a desktop PC, 24" iMAC, Xbox 360, (and two Windows laptops, and 2 Smartphones via WiFi).
Summary: I went from a Linksys WRT54G to the DIR-825, the setup was very easy, the range seems to be slightly better on the Dlink, the speed of the connection is noticeably faster. These are quite reasonable on the used market. If you see one, grab it.
