3 out of 5 eggsHorrible range

Pros: It's easy to setup, and the speeds when within range are great.

Cons: This thing has horrible range. I have it mounted on my office wall in the front of my house, right next to a window, with no other wireless routers or cordless phones in the house. If I'm outside, I can walk down the block MAYBE one house before getting out of range. Parts of my house are also out of range, or get a low signal, but that could just be due to the building materials in the house.

I tried 2.4 and 5 channels, and I saw similar results with ranges.

Other Thoughts: It's just not worth it.

4 out of 5 eggsFine with latest DD-WRT firmware

Pros: I was reluctant to purchase this given some of the low reviews I've read. But Newegg gave me a 30 day return on it if it didn't work.

* After installing the latest DD-WRT firmware (19154) from the Buffalo support site *AND* choosing a mid-band Wi-fi channel (6), I'm able to get a steady 22.5 dBm (EIRP av.) / 29.7 dBm (Peak) signal on 2.4 Ghz and a little less on the 5Ghz band. I think with some fiddling I can get it to go higher, but right now, this is more than enough for me, and more than enough to annoy my neighbors.

* Gigabit LAN. Excellent.

* Dual Band (2.4/5Ghz) is really a plus. I had some devices that had a 5Ghz radio that I didn't know had it. Neat.

* If the DD-WRT interface is too intimidating for you, you can use Buffalo's "User Friendly" firmware

* Mounting a USB drive and printer was simple (you can only do one at a time)

* Plenty (not gobs, but plenty) of RAM vs my old WRT-54GL.

* stable for 3 weeks now. No reboots or lost connections.

Cons: * A little too "plasticky" for my tastes. Be gentle with it.

* fixed/permanent antennas. Bummer.

* wireless throughput is not as fast as I was expecting. It's fast enough for most applications, but I was expecting more than a moderate boost over my WRT-54GL. I need to do some more testing and tweaking (DD-WRT is perfect for that).

*USB seemed a bit slow, although I was able to stream a movie off a 64GB SD Card in a USB to SD card adapter.

Other Thoughts: I've been a long time Linksys WRT-54GL guy. I have 3 of them in in my house all running variations of DD-WRT. But I needed the Gigabit LAN and a little more power both nicely provided by the WZR-HP-AG300H

3 out of 5 eggsThe good the bad and the ugly.

Pros: The good:
Has good processing performance compared to my old wrt54gs. A large amount of flash 32MB and memory 128MB.
This allows me to use it for more than just routing which is why I bought it.

Cons: The bad:
Power output is low. it appears the power output never actually goes above 16dbm ( 39mw ) combine this with the poor 3db antennas and it makes for a wimpy power output.
My old wrt54gs puts out as much power at 12dbm (can be set as high as 20 dBm safely ) combined with its 7dBm antennas as this router can put out at it's max setting.
The power cord is short barely long enough for putting on a desk much less anything higher.

The ugly.
The case is just plain cheap. The plastic case is as thin as I have ever seen used on a router.
The stand falls off easily when mounted vertically. This lead to a scuffed up brand new router when I made the mistake of picking it up by the stand.

Other Thoughts: This could have been a great router by adding removable antennas, letting the power be adjusted to at least 20dBm, making the case thicker and the stand stronger and actually stay on. Instead iit's just a fair router. ::(

5 out of 5 eggsReal world testing

Pros: Excellent range and stability once you update the firmware to the latest on Buffalo web site. This router has excellent hardware stats and can handle a number of wireless and wired clients at the same time. There are plenty of options and settings to allow you to streamline your network to prvide you with what you want and need.

Cons: The firmware preloaded is buggy and many have problems with signals/clients being dropped. I didn't drop an egg for this because the problem has been fixed as far as I can tell in the latest firmware update provided on the Buffalo website.

Other Thoughts: I purchased two of these at the beginning of 2012. I have one in the house that provides access to my private side of the network and another place in a container(5 gallon pickel bucket) on a pole 35 feet in the air for the public side of the network. The one on the pole covers over 8 acres of land both inside and out side of structures. No special mods or anttenas where needed. The only mod I made was to the container to allow for proper air flow, cabeling, and mounting for the unit. I can now watch any movie in my libray anywhere in the neighborhood or watch live TV from my HDHomeRun. I honestly can not tell you all the great things about this router in such a limited space. As with all things please do some reading and researching on your own before making purchases. I read many of the reviews below and have to wonder how many simple failed to do some reading to correct thier problems.

4 out of 5 eggsAlmost Returned

Pros: Good range through a 3000sq foot house built 100 years ago. Better than a major competitors router which rates the highest on newegg.

Cons: Dual band wireless N connection would not connect to anything. Tried buffalo's firmware and the DD-WRT, still wouldn't work. After 3 months wifi would disconnect several times a day. Didn't use the wifi much though, so didn't care.

Other Thoughts: Now I'm moving and I'll be connecting to a shared connection. Went to their website and downloaded the latest DD-WRT Professional firmware released 2012-07-10. Fixed the problem right up. Was about to call them for a replacement too.

4 out of 5 eggsGreat hardware, geek-friendly

Pros: The radios and switch in this router are solid, and the included software is good.
Manufacturer support for DD-WRT means it's well-supported and will be for a long time. Upgrading to Open-WRT is a great option for the geekier folks.
Signal and speed are good even through a couple of floors and walls.

Cons: No external antenna jacks, so you're stuck with the factory antennas.

1 out of 5 eggsCompletely Disappointing

Pros: Good range (when it will recognize and allow the device onto the network).

Cons: 1. Frequently fails to recognize devices that have been attached to the network multiple times. Advises that the devices do not have the correct security settings when, in fact, they do. No firmware update nor different settings resolve the problem. Disappointing. 2. The interface is overly complex. I can appreciate the need for intricate settings, but when this is coupled with a lack of instruction or explanation, it is useless.

4 out of 5 eggsGood specs for moderate price

Pros: DD-WRT pre-installed (saves that step); dual band; solid specs for the price (128MB memory, 32MB flash storage) for $95 (in May 2012). If you like power and space to mod/tinker, and don't want a big price tag, this is a solid choice.

Cons: Physical package won't wow you -- it's very plastic-y and feels a bit less than substantial in your hands -- but who cares? You're going to stick it in a corner and rarely set eyes on it.

Other Thoughts: The unit I purchaesed shipped with DD-WRT v24SP2-MULTI (03/21/11) std - build 16519. On this hardware, it has a known issue in which MAC address cloning isn't preserved for the Internet/WAN address on reboot. No worries -- if you need this function, this script will solve the problem:

3 out of 5 eggsuneven signal

Pros: fast hardware, works with openwrt

Cons: signal quality comes and goes on 2.4ghz band. client is a desktop coputer, so the problem isn't caused simply by the device moving around.

Other Thoughts: i chose this one for its purported 300 mbit/s bandwidth. no one said that only half of that is likely to be achieved with any single device.

1 out of 5 eggsDisappointing

Pros: Price, DDWRT, phone support

Cons: Reliability

Other Thoughts: Buffalo was highly recommended to me and I was happy to finally own a DDWRT router. When I first got it, I had problems with my iPhones connecting, called tech support and hashed that out. unfortunately this was not my only call to tech support. The router tends to loose its internet on the wireless side. I can access the admin panel just fine, but when it comes to getting online, no go. the wired connection works just fine but thats not why you buy a dual band wireless router is it? Speaking of the dual-band. I guess thats something I didn't realize either, a lot of devices, such as iPhones, iPads, etc won't run on the 2nd band. Their support has been great, they have offered to send me a 2nd device, perhaps this was just a lemon but from what I can gather, a lot of others have had the same experience.
