Summary: This has to be the worst wireless product ever. I have two of these and they both have the same issue, and I've battled with them for about two years. This cannot be a Cisco product!. Firmware is at level 2.04, the last ever released.
Excellent Management options, but it does not work
6 August 2011
Summary: We purchased this unit to replace a Lincsys router/AP in our office. The unit has excellent range and excellent management options. However, it does not function properly. We have it operating in mixed-mode 2.4Ghz and after a few people connect to it, it stops working.
Summary: When this first came out apparently it sucked, but I deployed five of these in a clustered environment all with the latest firmware and they were incredible. Excellent signal, no reported dropped connections in over 3 months of use, excellent clustering support.
Summary: I purchased this unit to replace a Linksys unit which has limited range. The Cisco wireless access point was expensive but their promotional literature claimed a much wider range than other units. The Cisco unit works for a few hours then fails even when you are close by.
Summary: Cisco had a lot of bugs with early firmware, since this is their first Linux based access point. However, if you run their latest firmware (1.9 as of this writing), the device is rock solid. I replaced some older 2.4GHz-only access points with the AP541N, and so far, it's been great.
Summary: Wi-Fi connectivity is very poor. Had this product for less than 20 days and it was enough to had it returned. Connection drops and low throughput are among the bad side of this device. Cisco could have done a much better job on this Security Appliance.
Summary: Had a few minutes of trouble at first, but after upgrading the device to the newest firmware, this thing runs like a champ. I am considering replacing all of our old AiroNets with Cisco Ap 541N access points. It has been going solid for 4 months without a single blip.
Summary: This product was purchased to be used in a corporate environment and to sum it up, it doesn't work well. It works much worse and is much slower than a $90 consumer router, Asus RT-N16 that is loaded up with Tomato firmware.
