Amazon Vine™ Review
(What's this?)
I'm not sure why people are having such problems with their DIR-665 Xtreme router - I am happy to report that after three solid days of use, the router hasn't even so much as hiccuped for me.
My DIR-665 from Amazon Vine is replacing my purchased D-Link DIR-655 Extreme N Gigabit Wireless Router. For those who know the older DIR-655 model, you will find the updated DIR-665 to be very familiar. In fact other than some cosmetic changes to the faceplate, the physical body is exactly the same between the two products.
I'm an IT person so of course I don't read any of the instructions or follow any of the guides. Out of the box I remove the DIR-665, notice it uses the same power adapter as my 655 so I just pull the local LAN cables, the WAN cable and the A/C Adapter and swap them over to the new 665. I'm in cable-internet country (TWC) so unfortunately the cable modem is somewhat fussy about dynamically releasing and renewing IP addresses on the fly to a new MAC, so I had to unplug/replug the cable modem in order to initiate a power cycle. After that, internet connectivity on physically connected machines was up and running.
So to recap:
1 - Unbox DIR-665
2 - Move LAN/WAN/A/C cables from DIR-655 to DIR-665
3 - Reboot cable modem
4 - Internet is go!
Wireless connectivity was a tiny bit harder since I had a specific pre-shared key that I wanted to keep in order to make reconfiguring my wireless connections easier. In that same theme, I kept my SSID name the same from when I had the DIR-655 installed. This was the first time I cracked open the web-based router configuration (192.168.0.1). Step 1 is always to change the basic blank password to something you'll remember. Step two, I simply did a once-over on the internet settings - every thing was auto-set to dynamic (which is normal for most ISPs nowadays), however if you have specific PPOE or other authentication requirements, they were all laid out here.
I noticed that the wireless config had the option of going through a wizard, so I selected that option first. Wizard is a bit misleading as you assume a wizard would explain what the options you were selecting meant. This would be my biggest gripe about the DIR-665, you really do have to have some knowledge of what you're looking at, setting-wise. Unfortunately the web-based configuration does not help in any way, there are no "?" popups or descriptions. You'll have to Google in order to find out what all the settings mean (which may be an issue if your router is down). The wizard seems to default to the widest acceptance settings, not locking out any wireless configuration, leaving security open to WPA or WPA2 and running on a closed 20Hz channel width. I didn't play around with the wizard too much so your personal results may vary.
Next, I went into manual wireless configuration in order to set up my personal preferences (a screenshot of my settings is included in the Amazon customer photos). Once I had moved to the 5GHz band, mixed 802.11a/n, Auto 20/40 Hz, my laptop reports 216-270Mbps connection speeds (screenshot also included).
One thing to keep in mind with the DIR-665 is that it runs a bit hot (again, just like the 655), so make sure it has ventilation room.
Since installation I have had zero issues with my DIR-665 - my laptop did initially have disconnect issues when I first switched to the 5Ghz spectrum, but a quick driver update for the NIC fixed that problem. In my home there are four wired computers, two wireless laptops (one 802.11g, one 802.11n), an iPod, two XBox360's (one with the new 802.11n adapter, one with the older 802.11g), and a PS3. Almost all of these devices work flawlessly. Streaming HD content from Netflx (via XBox) takes less than ten seconds to buffer. When you switch to the 5GHz network the protocols are limited to 802.11a and 802.11n. Therefore, if you have older devices that only run on 802.11g networks, they will not work when set to 5GHz (this could include iPods, phone WiFi, laptops, consoles, etc, etc). So check your wireless NICs, this may not be the router for you. Of course you could always get a secondary 802.11g WAP to hookup to your DIR-665 (this is actually what I ended up doing). For "gamers" this is how it breaks down for the 5GHz spectrum - the only units that will be able to use the 5GHz network will be XBoxes using the external "black" version of the 802.11N wireless adapter. This means that XBox 360 "slims" and PS3's will not be able to see the 5GHz network. The 360 "slims" can use the 802.11N black wireless adapter if you wanted to hook it up.
Now whether or not you'll be able to get the full oomph of the theoretical 300Mbps speed out of the dual band router is so dependent on your home configuration that it's probably silly to even try and address. Just know that just because something runs in the 5Ghz spectrum it does not mean that it's better than a 2.4Ghz device - we're not talking CPUs here, bigger does not always equate to better. Ideally the DIR-665 when in 5GHz mode is utilizing both the 2.4 and 5GHz spectrum (I really don't know how to check if this is true - if someone has a guide, I'd be willing to give it a try) and using the concept of channel bonding in order to use dual channel communication. I never saw the magical 300 number reported by Windows on my wireless NIC, but it does stay over 200 constantly and maintain a full 5 bars of signal strength.
Misc info - My router is located upstairs (laptop/xbox downstairs) in a home built after 1990. There is approximately 18ft of distance as the crow flies, but that goes through the roof/floor.

*Update 12/20/2010 - Just writing to let everyone know that I've been running this router for a little over a month and a half. Still works like a champ with zero issues. The laptop I'm writing this update from is reporting a 270Mbps connection as we speak.

Amazon Verified Purchase
I was replacing my DIR-655 with this DIR-665 after many good years of service from the 655. Not only do I like the D-Link routers for their quality, but also for a well designed Control Panel and Features. The thought of keeping up with the latest technology and having the 5 MHz available with the DIR-665 was comforting as well. However, it was a whole different story after setup. Initially, I stayed connected for a few hours. After that, I couldn't stay connected for a few minutes. It was extremely frustrating and I wasted no time in returning it. I have been around the block a few times when it comes to setting up a router or two for my home network, so I was not lacking on knowledge in this case. This DIR-665 just didn't rise to the challenge and I had no interest in trying another one.
I may look again to the DIR-655 as a replacement for my current DIR-655. When I bought the DIR-655 years ago, it was ahead of the curve and still has many good features that are desired today. I'm not sure yet, but will take suggestions from those that have a newer router with high performance and good features.
.
UPDATE 04/06/2012: I did, in fact, get the DIR-655 after all to replace this one. As predicted, the DIR-655 performs very well and I'm happy that I returned the DIR-665. Thank heaven for Amazon and how well they treat their customers. No fuss in returning it.

Amazon Vine™ Review
(What's this?)
The good:
This router gets great range for the wireless network in our house. I can get wireless now in the far reaches of the basement or upstairs, far away from the office where the router is set. Really, the range is so great I can live with the other hassles and shortcomings of this router.
It looks classy.
The bad:
I also wasn't able to get the LAN port on the router to connect to the WAN port on my SPA-2102 VOIP adapter, which was a hassle (it worked fine when I made the same connection through a 8-port switch). The only way I could solve this problem was to use a second router which could connect to the VOIP. I assume it's some sort of auto-sensing issue, but I didn't really want to spend the time tracking it down. The only way I could solve this problem was to use a second router which could connect to the VOIP. For non-techies, that means that it messed up my Internet phones and basically I can't use this unit with them.
Changing configuration settings requires you to reboot the router for each setting you change, which can get tedious.
It comes unsecured.
It doesn't seem to support IPV6.
The LEDs are too bright. I keep the router on my desk and they are so bright as to be distracting. I'm going to have to tape over them so they don't drive me nuts.
In a nutshell, I'm so happy with the range I'll deal with the other issues, but it's not like this is my dream router. When I realized it had caused all my phone problems, I was ready to give it eleven billion negative stars. But at this point, I need to acknowledge that the range is exceptional and it's going to be good from now on.
