Summary: After weeks of research for a dedicated \"gaming\" router, I finally bought the D-link 4100 with the latest Gamefuel technology. I was skeptical at first, but no other company offered anything ground-breaking for online gamers!

After playing online games such as Counter-Strike and BF, I am convinced that this is the best router for anyone serious about Low Pings! And this is the key to staying alive. The set-up was pain-less and I was up and running in 5 minutes. The case itself looks very cool with the blue LEDs. I did not go for the wireless version, because I wanted to use a Belkin Pre-N wireless as an access point.

At first, I thought the 4100 was too expensive, but now I think it's the best investment for playing online with multiple computers. Now I can host a LAN party and not worry about large packets slowing down the router! You can even download and not affect others playing online. I've also noticed that downloading huge multiple files seemed faster and at a constantly high speeds.

To sum it up...this piece of hardware delivers what it(and all the reviews) claims! The only thing I regret is not getting it when it first came out...

Summary: The biggest feature of the DGL-4100 is D-Link's \"GameFuel\" which automatically detects many online and network games and gives their packets higher priority. This helps prevent \"lag\" that may occur if your bandwidth is being used heavily. It also supports UPnP (in the latest firmware, which the device will update automatically) so non-gaming things like Internet telephones will work better too. It also includes a gigabit switch so, if your computers and wiring supports gigabit, you will get truly blazing networking performance. Moreover, if you want to hold a huge LAN party it delivers there, too. You can easily connect other hubs or switches to this router (it will automatically support them whether or not they have uplink ports) and connect many, many computers - this little black brick can support up to 6000 users! If you want the very best wired, consumer priced router you need look no further.

Now to the problems. There is absolutely nothing wrong with this router I can find, but that being said it is almost definitely overkill for a large percentage of home networks. You can buy any number 100 megabit routers for about $20 but this one costs over $100. Understand, that is an excellent price for a gigabit router, but you will only benefit from a gigabit connection if you have 1) two or more very fast computers, 2) gigabit network cards and 3) Cat 6 or Cat 5e cabling (or if you intend to use this router as a backbone to a large network). Also it should be noted that this router will not affect the speed of your Internet connection. Downloads won't be faster and if your connection is \"laggy\" it won't help with that either. It will really only help high-end users become even more high-end. If you're one of those lucky people then you really can't go wrong with this great little router. If you just have, say, two computers and only use your network for browsing the internet and sharing a printer then you would do much better with a low-cost option such as the D-Link DI-604.

Summary: I bought this router to replace an aging Netgear Cable/DSL router I've had for a few years which gave me nothing but trouble the entire time I had it. I had thought some of this was my Cable provider's fault but quickly found out it was the Netgear's fault once I hooked up this D-Link router. I leave my PC on 24/7 and am always connected to IRC among other things, with this D-Link I rarely see any disconnects and when they occur they're always caused by external problems (a server drops, the cable goes off, etc.) Everything's rock solid stable now, and I even get much, much better performance from bittorrent downloads than I used to. Getting more technical I can leave SSH sessions open to remote machines for literally days without them locking up. With my old Netgear they'd lock up within 15 minutes of inactivity. (They're not supposed to lock up like that.)

One of the things I love best about this router is that I can add/delete/change port forwarding rules without causing any disconnects of active sessions. This is more in line with what you expect when you get to the commercial level of routers (brands like Cisco that cost a LOT more than this D-Link) and is quite handy. Once you start looking through the advanced configuration you'll see that this router can do pretty much anything you could ever want and then some. It's logging is even far better than most consumer level routers. Also mine wouldn't actually pull an IP from my Cable modem to connect me to the Internet until I ran through the setup and changed the default password. This impressed me greatly as it's the first consumer level router I've seen do this and it definitely adds to the security.

Bottom line: while you pay more upfront for this router you get more than you pay for. This router simply works better than most of the Cable/DSL routers out there on the market and should last for many years of use. Spend the extra now and you'll be glad you did!
