Ap 541N Wireless Access Point Review

Ap 541N Wireless Access Point
Average Reviews:

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. I'm running this in 5.0GHz mode (802.11a/n) due to local interference on the 2.4GHz band. Note that this access point, while claiming to be dual-band, has only one radio. This means that it can only operate one of the frequencies at any given time, so you can run it in 2.4GHz mode *or* 5.0GHz mode, not both concurrently. If you still have older 2.4GHz clients (802.11b/g), you will need to either run this AP in 2.4GHz mode, or run a second AP to support the second frequency.
For advanced users, this device has a couple neat features. First, it can run a number of SSIDs concurrently, each with different security models, and associate them with VLAN tags. On our network, that enables us to run a "Guest" network with limited access to resources, along side our "Internal" network. It can also replicate it's config to multiple AP541N access points within the same network, enabling you to manage them as a single mesh, without having to purchase the complex (and much more expensive) managed wireless infrastructures. FInally, it runs the Linux OS on a Cavium MIPS CPU, and has a full SSH daemon and busybox shell environment, so I'm sure there's some creative modifications that an advanced user could run on this access point.

This product is rushed to the market but not yet ready for prime time.
Issues:
1) If you are using VPN to access your companies network - forget it, this product won't allow you to connect (will not pass IPSec-L2TP or PPTP traffic through)
2) WEP encryption doesn't work - yes, you can enable it but after 3 min you will loose connectivity with you wireless network. With WEP disabled connectivity will stay up.
3) MAC filtering doesn't work also - the router will reset back to default (Disabled) setting as soon as you submit changes to it.
4) Changing Internet Filters setting will reset this router to factory default.
5) Firewall is also not performing well.
6) Tech support is "dancing" and you won't give you any type of answer when they will come up with firmware upgrade - they won't allow you to talk to a supervisor also - USELESS.
On my scale from 1 to 5 this product gets 1.5.
RMA
