Summary: The setup was super easy and being able to see this from the cloud is cool. However, I was very disappointed in the performance. My wireless internet slowed down to a crawl compare to the old Linksys that I replaced. This router also locked up 2 to 3 times weekly. I ended up sending it back in for a refund.
Summary: The D-Link DIR-636L is a basic, single-band (2.4) Wireless-N router that would be well worth considering at a lower price, but its high price makes this relatively bare-bones piece of hardware hard to recommend despite its full-featured software. The router's lack of dual-band support is a major deficiency for its price point, and it does not appear to be a very high-performance or high-reliability unit, exhibiting occasional lag and one crash in my first day of testing.
Summary: It's easy to set up and the signal is strong. Only one critical downside: P2P is shut down with unknown reasons. I tried to check the UPNP settings. It doesn't work out. I still cannot download things via any P2P downloader.
Summary: I bought this router to replace my older 615 (N150 router) because I liked the USB connectivity story... unfortunately, it is really for some smart phone apps as I could not figure out how to conifgure to share files with Blu Ray devices/DLNA certified devices. I returned is and opted for the WD Live 3TB NAS which has DLNA inside.
