Summary: It of course always hard to say whether you got a bad unit or whether all are bad. I know for sure that my router is unreliable and conclude from the other reviews that at least the quality control in the production of this router is very poor.
Summary: I have used this router for over a year now, and I have finally had enough of the darn thing needing to be unplugged for 5-10 mins after any power hiccup. I've never tried the 'freezer method' that Uwe uses (see below), but I have the exact same issue on a Rev D product.
Summary: I bought a DI-524 about 2 years ago for our home network. We are connected to a microwave link, so it is an ALWAYS ON connection. The router works... most of the time. Sometimes we lose the internet, usually after a power outage. The problem is the router.
Summary: Marked as new; the WAN port was faulty (unable to receive the internet, I had to use one of the other number ports for this) and I also spent 50 minutes on the phone with D-Link customer support, who deduced that the wireless was also faulty (no matter what it would not transmit).
Summary: I totally agree with frustated people who bought this after reading other's good reviews. This product has many revisions. Atleast do not buy Revision 'D'. You can have a look below the product for revision number. It SUPPORTS :) multiple freezing and it does it without any known reason.
Summary: I bought this router after a friend reccomended it to me. I followed the instructions exactly yet the connections kept resetting continously. I contacted the manufacturer three times and they were unable to solve the problem. I also called my Internet Service Provider and they were no help.
Summary: This router has a great price, especially when on sale. The firewall (built in) is pretty good as well. But the problem with D-link, with their 500 series is that it disconnects you from the internet occassionally.
Summary: the connection speed and ease to use are all fine. but it crashes too often. seems like it's sensitive to the electricity also. besides the everyday , now and then crash, it crashes when ever i have power surges....
Summary: well, ive had this for maybe a year now maybe a little more or maybe a little less, cant recall to be exact but it has finally given me enough crap that i had to go and buy another one. for the past 2.5 weeks i lose connections once aday.
Summary: I got this router free from Verizon with my FiOS broadband service. Performance-wise, it offers very fast connectivity, whether wireless or wired. The wireless range is more than decent, althouh I am not using it in a multi-story environment which normally provides the most challenge to wireless...
