Linksys Has Some Competition! (See updates at the bottom)

ByJerry Palmerino JrVINE VOICEon November 10, 2008

Vine Customer Review of Free Product( What's this? )

I am a Linksys person and I teach a Wireless course using Linksys products. I have been using Linksys products since their 802.11b wired routers first became available. I recently purchased the WRT610N and after trying this D-Link, I am sorry I chose the Linksys WRT610N.

As my first D-link product, I failed to realize D-link uses a 192.168.0.1 network address for its router. I am used to 192.168.1.1 on Linksys products.

PROs:
It is a Dual-Band wireless router, just like the WRT610N. It allows you to schedule wireless access. It has a great manual, which even tells you how to hook up one router to another for extending coverage. I was surprised to see this. I like being able to adjust power output of wireless radios. I love the idea of Guest wireless internet zones. It allows guests, such as friends, to get on your network without having access to local resources or giving out your normal SSID/Password.

It clearly has more options than the Linksys WRT610N, which can be seemingly less user freindly and requires more knowledge of networking. The web configuration screens are similar to Linksys screens though. Anyone familiar with Linksys can find their way around. I did not try the setup CD. Instead I manually configured it using the web interface.

I did not experience any of the instability issues I had with WRT610N. With a Lenovo T61, Apple TV, iPhone, two Macs, a PS3, and a PC connected to a Buffalo LinkStation Gaming Adapter, I needed to find the least common denominator wireless settings in order for all of these devices to connect and stay connected successfully. There were just too many disconnects, which necessitated the least common denominator approach. This approach meant I had to choose "Mixed BG" instead of "mixed (which includes n), had to set channel width to 20, and had to use Tkip WPA only. The D-link allowed me to use all three speed grades (B, G, and N) with WPA or WPA2 (becuase it autodetects the best encryption method available with client devices). I was also able to set the Channel Width to auto (40 or 20 depending on the clients).

CONs:
It only allows up to 63 alpha characters for the wireless passphrase/password. I prefer 64 hex character passwords.

The menus are a bit more complex, which could be an issue for some.

Only one person at a time can access a USB hard drive attached to the D-Link wireless router. Many can access the USB hard drive hanging off of the Linksys WRT610N.

OVERALL:
This is a great wireless router. I tested it as a drop-in replacement for my Linksys WRT610N (after changing the subnet to 192.168.1.x) and it performed admirably. If you are looking, I would consider this strongly before purchasing any other brand.

DECEMBER 2009 UPDATE: When my company moved to a webpage-based VPN solution (we have to access a webpage and login which then opens up the tunnels), I discovered that the firmware version (1.01) I had caused issues. I upgraded to version 1.12NA and now I am experiencing daily wireless connectivity dropouts on the 2.4 ghz band. The only solution thus far is to restart the router. This new development has been detailed across the web. I am going to try some of the suggestions, such as any one or a combination of...disabling DNS Relay, disabling IPV6 on client computers, downgrading to 1.11.

SECOND DECEMBER UPDATE: After disabling the DNS Relay, I have been running for over a week with no issues.

D-Link HAS to be paying people for these positive reviews

ByUltimate Outsideron May 30, 2009

A couple of months ago I purchased the DIR-825 because on average it received better buyer reviews than the competing dual-band N-compatible routers. At this point, I'm really struggling to understand how this is possible, because the DIR-825 fails in so many areas. I've designed wireless home networking products for almost the past 10 years, and while I'd hope that my experience and familiarity with top brands should equip me to make good purchasing decisions, in my confidence I apparently overlooked some fundamental requirements. In the DIR-825 I got a router that had what I was looking for (configurable QoS, dual-band 802.11n support), but also had a lot of other "features:"

- Randomly disconnects clients every hour or so. This happened more in 5GHz than 2.4GHz, but it definitely happened in both spectrums, and did so often. The router's logs did not indicate any reasons for clients being removed. My theory is that there were frequent signal strength hiccups that caused clients to think the router had vanished. They always reconnected about 10 seconds later, but that's long enough to disconnect you from most online games.
- Renders Vonage VOIP calls completely inaudible, even when the wireless network is quiet. The Vonage router is the only wired networking device in our house. We had it plugged into the DIR-825 so we could take advantage of the router's advanced QoS capabilities, but it was an absolute nightmare. We never got VOIP to work right so long as it was 'behind' the DIR-825, regardless of QoS settings and various other tweaks mentioned in the D-Link knowledge base and forums. We ended up having to put the Vonage device in front of the router (which fixed Vonage but had side effects on the rest of the network).
- Auto-channel Select Feature DOES NOT WORK. The auto-channel select feature, which is enabled by default, is supposed to automatically choose the least congested WiFi channel in your band. I have access to some very expensive sniffing and spectrum analysis systems that tell me that the absolute best 2.4GHz channel in my house is number 4, and the absolute worst is number 1, which literally has 10 different SSIDs beaconing on it as I write this. The DIR-825 ALWAYS selected channel 1 (and it wasn't just a matter of what it reported in the admin UI; sniffers reported it in Channel 1.) Not only does this feature appear to do the opposite of what it advertises, it's also known for randomly disconnecting clients. Unfortunately, disabling it did not fix our problem with that.
- Doesn't work with BitTorrent. I know all about port forwarding, TCP, UDP, UPnP, I followed forums, FAQs, and step-by-steps, but I never got BitTorrent to accept incoming connections properly. (And note that I hardly ever have BT running, anyway; it has nothing to do with the other issues noted here).
- Crummy wireless range in both bands. First off, a little bit of info about the 5GHz band: 5GHz is never going to have the same range as the 2.4GHz range at the same transmit power; this is a matter of physics- higher frequencies = shorter wavelength = shorter distances/more susceptible to walls. There's another problem though- at least in the USA, you are only allowed to transmit on 5GHz at a fraction of the maximum power allowed on 2.4GHz, so really 5GHz is hit with kind of a double-whammy of suck. Note that there are a few 5GHz channels that are allowed to be transmitted at a higher power than the rest, but that doesn't mean that 5GHz device manufacturers actually do that- it only means they can. With that in mind, I can say that the DIR-825 has worse range in not only 5GHz but 2.4GHz as well than the dual-band Linksys WRT610 (which surprises me because of the Linksys's funky design), and also worse than any of the 2.4GHz-only routers we had before that.
- Is on its way to losing WiFi Alliance compliance. There's a WFA-certified logo on the box of the DIR-825, but if you've been following wireless forums you will learn that D-Link has been experimenting with removing 802.11b support from their routers, including the DIR-825, in their downloadable firmware updates. Now, I personally stopped using 11.b years ago, and you can get better 2.4GHz performance by going G-only, but WFA logo compliance REQUIRES that you support 802.11b. D-Link has not explained why they're trying to do this, but I suspect that their hardware has either become overloaded or their code so messy that they can't adequately support new requirements without dropping 802.11b support- and that should scare you.

After a full MONTH of trying to get the DIR-825 to work properly, I realized it wasn't me, and it wasn't my setup- it was just that this router sucks worse than any other router I've ever used. I promise you there's not a single setting I didn't investigate or tinker with in my quest to get reliable WiFi, but honestly, even if there were some magic combination of router settings that would make things work, the thing should have been configured to work properly out of the box. I don't have any crazy setup, just a bunch of computers, and a few game consoles and TiVos that are normally quiet.

I purchased the Linksys WRT610N Simultaneous Dual-N Band Wireless Router and am MUCH happier now. I don't believe I had to configure any special settings except for the port-forwarding stuff for BitTorrent. I have Vonage connected behind the router again, and VOIP works perfectly. Our connection strength is better on all computers in the home than with the DIR-825, and the only random disconnects we get are on 5GHZ, though they are much more infrequent than with the DIR-825. Save yourself a month of headaches and get something, anything, other than the DIR-825.

P.S. About 802.11n - Note that 5GHz support is an optional feature of 802.11n at this time, so when looking for APs or network cards, understand that not all of them support 5GHz (in fact, most don't). Allways look for "dual-band" or "5GHz" when shopping for 802.11n stuff so you have the most flexibility in your home setup.
