Re: [HELP] Cisco 2821

built in wifi. dose the 2821 have dhcp functions or what would work best to get one router with dhcp and wireless in one? Im looking for something cheap but works well.

The 2821 (as well with most modern Cisco routers) has capability of being DHCP server though it may only offer basic functionality compared to full-blown dedicated DHCP server. You simply need to verify the IOS image the router runs has such DHCP feature.

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.

DHCP is part of IP Base, so it would have to be a router without an IOS or a broken router.
