Before buying this router, look at the comments on the D-link DIR-825 Forums. 1. It drops the WAN connection and it is very hard to reestablish. 2. When it dows work, the wireless performance is awful. My Slingbox only manages about 150kbps on my D-link DIR-825 + DAP-1522. Using my old Linksys WRT54GS and an ASUS miniature wireless bridge, I get over 2 Mbps. 3. It does not work well when connected to another router (page 10). I can't get more than 1 wireless connection in this mode.
I find this one of the most stable wifi connection I have. I might have so drop connection in bulk once, do a firmware upgrade to it or to my laptop fix it. I think I switched from static to dynamic and that worked much better.
