4 out of 5 eggsDecent, once you get it set up

Pros: This little AP has some pretty decent transfer speeds.

Right now, I'm sitting one floor up from the AP in an older house, without even great signal strength, and I've tapped out my FiOS connection at 25Mb/s. With my previous 54G and N APs running over 2.4GHz, this probably wouldn't be happening. I'm sure running it at 5Ghz is helping immensely, but I'm still impressed.

The GUI is pretty intuitive and it's a pretty feature-rich AP for a decent price. I'm actually thinking about selling this AP and upgrading to two WAP371's though for the 802.11ac capability and dual-radio ability.

Cons: It only does 2.4Ghz or 5Ghz; not both. Meh, oh well.

During setup, I have it trunked to my switch to pass multiple VLANs for my guest SSID and home SSID. There's a nasty little bug concerning syslogging and the native VLAN that will cause the AP to lock up frequently, but once you get around that, the AP is rock stable. You can search Cisco's support forums for the fix, I believe.

These little "gotchas" are the reason for 4, not 5 eggers. They're minor annoyances, really. Hopefully Cisco has worked these out in the later models, though. If not, meh.

Other Thoughts: This is a PoE AP for business. The people shocked it doesn't come with a power cord; if you work with enterprise wireless, you'll know that those Cisco APs don't come with a power cord either because they're PoE. Cisco assumes you're getting PoE because you don't want a wall wart.

4 out of 5 eggsEasy to set up, especially when using several

Pros: I've used this product in several installations. Its cluster configuration allows you to assign multiple access points to a group and when you change the configuration on one, they seamlessly propagate that change to all of the other access points in the group, which makes administration a breeze. All access points preset the same exact same network name to the client computers and have shown themselves to have good range

Cons: Who was the genius who decided to sell this without a power cord? That is sold separately. If you are planning to use this with power over ethernet, you won't miss it, but this is the kind of device you expect to have a power cord in it. Nothing worse than scheduling an installation, and arriving only to find out that you're missing a super basic item that isn't available in stores. This cost the product 1 star on the review, but I'm tempted to take off 2 stars because this issue is so offensive.

4 out of 5 eggsVery intuitive setup!

Pros: -The GUI is well designed
-Clustering multiple WAPs is incredibly easy
-Small footprint and wall mountable (potential con below...)
-Price (for a Cisco product)

Cons: -Wall mount bracket is poorly designed
-Some connectivity issues when devices connect for the first time
-No power adapter included (I'm aware it's PoE)

Other Thoughts: As stated, these WAPs are wicked easy to setup. I purchased 5 of these in total (the limit for clustering), and have 3 running right now without issue. I will add 2 more to cover the entire lab sometime in the near future.

The range is quite impressive for a lower end WAP and I've noticed no interruption in connectivity when moving between the 3 areas the WAPs are located in.

I do have to say that the wall mount bracket is poorly designed. You would need a network cable that had 2 perfectly spaced right angles near the connector for this to work out of the box. As mentioned in an earlier review, I had to take an exacto knife to the cut-out to allow the cables to exit the mount without putting a ridiculous amount of sideways strain on them.

Also, some laptops took over a minute to make the initial connection. There was no rhyme or reason from what I could tell as to why only certain laptops were affected. All smartphones seemed to connect immediately without an issue.

Overall I think it's a worthy purchase if you want to provide wireless access to a small to medium size office, via clustering, on the cheap.

1 out of 5 eggsCisco needs to address firmware issues

Pros: Solid hardware, small compact design, low power, and a simple GUI interface.

Cons: This WAP321 is the worst Cisco product I have had the displeasure to work on, and I have been working with various Cisco equipment sense early 1999. This Cisco WAP321 hardware is very solid, but Cisco’s total lack of responsibility to fix the software stability issues has me completely dumbfounded. Looking on the Cisco forums page this reliability issue has been going on for more than two years with no resolution.

I normally do not buy small business grade Cisco gear even for home. However my wife has been gently encouraging me to lower our total carbon foot print. So I bought this WAP321. This was to replace my Cisco wireless LAN controller and five Cisco APs which is total overkill for my 2.5k sq ft house.

The setup of the WAP321 was awesomely simple, in fact much easier than the enterprise counterpart. I was up and working in less than 10 minutes. However this was short lived about every 24 hours I would lose connectivity to both the wireless radio and wired administrative interface. To fix it I would simply reboot the device, I did this for two days before researching it. First I did just a googled search on it and was shock as to how many people are having similar if not the exact same issues. Many people suggested upgrading the firmware which would make sense if there was a memory leak of similar type of bug. The factory firmware on my WAP321 is so I upgraded it to the next rev but the problem still persisted. I thought it might be something in my environment so I have access to a testing lab with a separate set of switches very basic configuration within a Faraday cage. (For those of you that are unfamiliar with a Faraday cage it is an enclosed space that blocks all RF from leaving or entering.) When in the Faraday cage the problem still processed. I then took the device back home and tried firmware the problem still persisted. Then I tried firmware this rev I got a deferent reaction the problem went from having to reboot every 24 hours to having to do it every 4 hours.

At this point I was almost ready to admit defeat and go with a deferent competitor product or continue to use my enterprise Cisco solution despite my effort to reduce my carbon foot print. I looked on Newegg site and most reports were 5 stars but looking at the date the people could have only had the firmware prior to which is I downgraded my firmware to the version prior to what mine was factory shipped on. It has been working on for 30 days now no issue. I happy it is working and my carbon footprint has been reduced. I am however very concerned that as new security threats emerge that I will not be able to upgrade this until Cisco fixes this reliability issue.

Other Thoughts: I would hope Cisco fixes the firmware reliability issue.

1 out of 5 eggsUnexpected Failures....

Pros: Easy configuration, guest network isolation, management features for MAC addressing, separate VLANS, POE support.

Cons: It doesn't last.....Had 3 out of 4 of these go bad within a year (get's stuck in a constant reboot). Not ideal for any networks over 25 clients.....Two of our replacements have already failed with similar result (constant reboot). All were running latest firmware at time of failure.

Other Thoughts: We really never use Cisco products....have Netgear and D-Link routers / access points forever until deciding on these....poor choice....too bad you have to spend high dollar for a reliable Cisco appliance.

5 out of 5 eggsThese can cluster together

Pros: I love these access points. Easy to hang/mount. The cluster feature (easily setup via the setup wizard) is outstanding. I am very impressed with this product. My company has six of these setup spanning 5 buildings and they are rock solid. Did I mention I like the cluster feature?

Cons: I gave this product five stars. There really aren't any cons that I can think of. Just be sure you have a POE (power over ethernet) switch in your system.

5 out of 5 eggsWorks Perfectly

Pros: The installation and setup was super easy to get started. I have three AP's setup as a cluster and as I'm walking around the building the system automatically switches me the the best performing AP.

Cons: No cons right now

5 out of 5 eggs5 Flawless

Pros: Stand alone AP
VLAN Support
802.11 a/b/g/n

Cons: Requires seperate power supply purchase and or PoE injector purchase (to be expected)

Other Thoughts: I had the WAP4410N out of 13 I only have 3 left since they crash without warning and drop connections all the time. These WAP321 seem much much better. I have left two of them left on in high traffic areas without a reboot for about 8 months now running one back on lastest firmware as a test and they are running great!

3 out of 5 eggsMisleading Speeds

Pros: Great device in general. Lots of great options for a small business, including QoS and VLAN support.

Cons: The advertised speed of 300Mbps is misleading when used in the 2.4GHz range. If the 20/40MHz channel bandwidth setting is enabled, the device enforces a "good neighbor" policy if it detects a neighboring AP using a channel within +/- 40MHz (2 channels) of its own channel. What this means is that the AP drops to 20MHz and won't support speeds higher than 144Mbps. To Cisco's credit, this is compliant with the 801.11n-2012 spec and their tech support was great in helping me figure out the problem. But what it means is that older devices that don't have the 2012 regulations will support 40MHz (and 300Mbps) even though they will be considered "bad neighbors".
