I bought this D-Link modem/wireless router to replace a Speedstream 5360 modem and a Linksys wireless router. It works MUCH better than the other system I was using. This system has been very stable--no more random disconnects from the internet or continual problems with the wireless system that I was experiencing previously. The D-Link wireless router has a much stronger signal than the Linksys it replaced. My D-Link system is in a building next to my house (about 20 feet away) and I can reciev
e signals anywhere in the house on a laptop with no problem at all--the Linksys was only usable in one room. The set up was easy and I like the combination modem/router--does not clutter up the desk. D-Link has created a good prodcut for my application.

A decent choice, but definately bang for the buck; That's how I'd describe this gateway modem. There are some very fine features to this unit, but those come alongside some pretty big drawbacks.
In my usual fashion, I'll get right to the bad, then end on a good note.
My first issue is the heat. This modem gets hot enough, nearly to burn you at times, and I'm not exaggerating.
Secondly would have to be it's Web Interface, which just plain sucks. This is the same layout I saw in a DSL modem I u
sed nearly a decade ago, and it was just as bad then.
Third is usability. The manual which is electronic only, is worthless aside from setting up the modem's physical connections. It's a good thing this is a MODEM/gateway, which means you have internet. Google is your friend with this modem, and unfortuanately will be your only user guide of worth.
One more thing, not a true issue, but.. LOSE the fake metal and child-like silver painted trim, thins modem looks like a Happy-Meal pack-in!
OK. Got all those out of the way. Now for the easy part, what I *like about the modem.
Features, it's got a lot of em, and some QoS of some worth considering the price. It has very good set of features that I'm happy to have at my disposal.
I love it when a router throws in options I don't nexessarily *need, but like having. Some standard features seem to get lost in the shuffle lately, so here are a few features of note for the quick glancing consumer:
- QoS (decent at that)
- Port Triggering
- Multiple VPN passthrough (not just 1 tunnel, NOT VPN ITSELF HOWEVER)
- Proper DMZ (set rules are followed, but failing in finding a suitable rule, the router sends that traffic, solicited or not to the DMZ host)
- Annex M (when 24/3.5Mb service arrives, this modem is ready)
- Time-of Day restrictions
- TelNet Configuration.
Setup is a breeze if you have a rudimentary knowledge of computers (although some from AT&T service have complained about shoddy auto-config) and I was able to get this unit running in about 5min. It just really is too bad the GUI is so badly done..
All in all, I would surely recommend this modem/gateway based on it's feature set and price, but as you can tell, there are issues as well. If you aren't tech savvy, I'd be sure you ARE savvy with finding information on the net before taking the plunge, as you WILL need to look a few things up. If you *are Tech Savvy, and like your features, I'd have to say the features outweight the negative issues, and go for it.
Price for Performance: 4.5/5
Usability and Design: 2.5/5

Like the other reviewer, I also bought this to replace a SpeedStream DSL modem and a Linksys wireless router. Overall, I'm happy with its performance, but had some headaches with the initial setup.
SETUP: Be prepared to immediately call your ISP for assistance. D-Link provides a "Wizard" to help you set it up for the first time. However, the DSL configuration did not work with my ISP's settings. Luckily, my ISP's Help Desk is very friendly and easy to work with. After some back-and-forth with m
y ISP via email and phone, I finally got connected. If your ISP is difficult to contact, you may end up returning this modem after some headaches.
FEATURES: Overall, it contains all of the settings I was looking for. It has a fairly robust firewall with lots of options. The wireless configuration has all of the security settings as stand-alone wireless routers (WEP, WPA, etc). However, I found that the web interface is not as easy-to-use as Linksys or Netgear.
OPERATION: So far, so good. I have experienced less disconnects, which is part of the reason I wanted to get rid of my 5+ year old SpeedStream. However, I found that the wireless signal is not as strong, since the antenna is not very good. Honestly, I eventually took off the antenna from my old Linksys wireless router, which improved my signal from "Good" to "Excellent".
OVERALL: 4 STARS
