Re: [HELP] Cisco 2821
As Aryoba said, it depends on the image the 2821 is running. As far as all-in-one, you can get such a device, but it introduces a single point of faliure. Getting a seperate access point/controller allows you to go with a vendor other than Cisco if you wanted to. Depending on your needs you could look at Ubiquiti, HP, or Aruba Networks as alternate vendors.
Even an external access point presents a single point of failure.
Lose your AP and a good chunk of your users will be offline or inconvenienced, just as they would be if the card in the router died.
If the router dies, an external AP doesnt really help you anyway.
Think of it in different terms, its a single point of administration, and easier to install. Ship the box to the site preconfigured, and even the ditzy receptionist can get it up and running.
In the case either device dies, you have more to worry about than any individual component.
If you really want to avoid outages, then you need to invest in a full 1+1 setup, redundant routers with redundant WAN circuits, redundant switches, APs and controllers.
