I did n't get any range improvement in one area of my house and my main laptop is still around -60db
What is the range?
I replaced my Trendnet 633GR router because I had a lot of high volume devices that were all consuming bandwidth and bogging each other down (Netflix, XBOX, Slingbox, laptops, etc. etc)  I wasn't getting full "G" speed with the Trendnet 633GR on my primary laptop so I figured I'd try out the Netgear WNDR3700.The big plus for this router is the 680MHZ CPU.  Even though I can only get data from my broadband router just so fast, the router seems to be effortlessly routing everything in my network without any slowdowns.  Unfortunately, I didn't get any range improvement in one area of my house and my main laptop is still around -60db (and about 1 MB/s)  I was hoping to get a little more but the faster router processor seems to keep the data flowing very steadily.  If I use a USB network adapter on my laptop, I get full speed.  I suppose I could blame my laptop network card for a weak antenna.As for the 5GHZ secondary band, I didn't find any use for it.  If I got further than 30 feet from the router and had any obstructions, the signal was just about useless.  I was -90db at 40 feet thru one wall and the ROKU XR failed to hook up.  I eventually just turned the 5ghz radio off on the router.One other thing I like is a guest network feature.  I can turn on a generic guest network when we have visitors and let them get on the internet.  I still have all encryption methods available.Overall, very solid router, I am happy and this router will probably last me a long time.  I found that Amazon actually beat Newegg prices by 15$...UPDATE 2/4/2010 :  I had a VPN server running with no problem on a Windows 7 64bit machine and a Trendnet 633GR Router.  I switched to this WNDR3700 for reasons listed above.  The WNDR was ALMOST perfect except I was simply unable to get the WNDR3700 to passthru a VPN connection.  I have to have VPN for my situation so the router is going back.  I noticed after a lot of hair pulling that others are waiting on dd-wrt firmware to rectify this VPN issue.  I'm surprised that this router couldn't do VPN, it seems so necessary??  I suppose I'll try it again when it has VPN capability.UPDATE 9/10/2010 : Somehow during a firmware update VPN is now working in Windows 7 64bit.  My network is flying.  5ghz is turned off because the range is so short that it is practically unusable.  5 STARS otherwise.
