I have used the Netgear WN802T for a few years now. I bought it along with a bunch of other Netgear equipment at a CompUSA going out of business sale at 70% off. I sold most of it on Ebay but I kept the WN802T along with a couple 802.11N PCMCIA and PCI cards. I also kept the Netgear FVS318v3 firewall/router and VPN endpoint which serves as the first line of defense for my network. A device which seems to be completely bulletproof in terms of handling game hosting, bittorrent, and whatever else I throw at it without crashing, a rare gem indeed.
The WN802T is not so lucky. I’m on my third since the previous two self destructed under the heavy load of handling my laptop internet surfing. The WN802T is just an Access Point with no router capabilities of any sort. My warranty is now expired and it’s only a matter of time before this one just gives up the ghost so I decided it was time for a new AP.
I did a lot of research on this one and landed on the D-Link DGL-4500 router. Now I know half of you are saying “D-Link? Eww!”. But let’s let time tell on this one. First off I have no brand loyalty when it comes consumer grade networking problems. Most every device out there is shit with a few specific models which are the diamonds in the rough. I have owned enough different brands of fail routers to focus on models. Which left me reading about 40,000 reviews. These are also difficult to trudge through since most of these reviews are written by idiots who never truly understand why they have networking issues. There are plenty of people who will give a router 1-star because it doesn’t work for 500 feet or because they can’t figure it out or they see their neighbors access point or they have a 2.4Ghz cordless phone. So you got to weed through the idiots and focus on reviews where these people know what they’re doing.
And the DGL-4500 gets good marks for wireless stability which is the only metric I care about.
But let’s focus on the negatives. First off, D-Link isn’t a company known for quality. Most of their crap is shit. But a few of their recent routers get actually decent reviews. A streak of good designs is always a good thing for me. Secondly, they’re marketing this thing for gamers. This is so they can charge much much more than this thing is worth for it. It has a high resolution LCD display which is ABSOLUTELY WORTHLESS. I can’t imagine a need to ever have it on something that has a web interface.
It has three external and removable antennas which is nice. It has a 4-port gigabit switch which is also nice. The router functionality which is supposed to give some sort of QoS priority to gaming (UDP?) sounds nice though I’m not using the router portion of this thing. Setup wasn’t bad. It’s pretty easy to configure.
Oh, and it seems to work with all of my devices. This is the one reason I didn’t go for the Apple Airport Extreme. The Airport has similar features and supposed rock solid performance. It’s also notorious for not working with the Xbox360, Wii, PS3 and a myriad of other wireless devices not made by Apple. Boo.
This brings me to 5Ghz. The 5GHz band which is supposedly cleaner than the overused 2.4GHz band sounds great in theory for wireless devices. The DGL-4500 is infact a dual band router except it either operates in 2.4GHz mode or 5GHz mode. This is unfortunate because all my 802.11 gear I own is 2.4GHz and many of these devices (PS3, Xbox360, Wii) are not able to run in 5GHz mode. There are some routers capable of operating in both modes at once with limited success.
Cordless phones are powerful wireless devices. I’ve had 2.4GHz phones that could work from the car half a mile away from my house. Many of them are spread spectrum devices which ads security but REALLY starts dirtying up the bandwidth. These phones are common and dirt cheap and the bane of anyone with WiFi. WiFi APs themselves are quite prevalent even though most people DON’T need them. Companies like Verizon install APs willy nilly even for customers who don’t have more than one hard wired PC. It’s a feature that’s flooding the AP channels with bad signal.
5GHz works because there are less devices on those channels. I suspect there is also a little more room so more channels as well. 5GHz is also a bit more personal. It’s range is much more limited compared to 2.4GHz and it’s also more affected by things like walls. Since a strong wireless signal is really important for decent speed, 5GHz isn’t necessarily a win for performance. Also there are plenty of 5GHz wireless phones now. I own one. I bought one because my 2.4GHz phone would start dropping the wireless.
I don’t think it’s necessarily worthwhile to upgrade to a 5GHz network right now. However I fully intend to get a dual band USB adapter and give the 5GHz band a shot.
Back to the real world, I’ve been using the DGL-4500 for a few days now with questionable success. Using my old Netgear PCMCIA card in my laptop, the device I was having the most network drops with, well I was still getting dropouts. I switched from the 802.11N card to the built in 802.11b and the dropouts don’t seem to occur anymore. Internal WiFi usually has much better antennas than external adapters. But I suspect the Netgear software itself was a cause for the drops.
On that note, the laptop with the Netgear card used to get a steady 270-300Mbps link that dropped to about 90-110Mbps when I wwent to the D-Link. Signal strength looked the same though I have yet to run any SNR comparison tests. Maybe this weekend. Anyway, that’s a serious performance drop which is either more honest than it used to be or some sort of N incompatibility. Since N doesn’t seem to be a ’solidifed’ technology yet, these sort of cross vendor problems are not surprising.
