Difference between the 1800 and 2800 series routers

Unanswered Question

Can someone give me some quick pointers of the differences between the 1800 series router and the 2800 series router?

Why should I buy the 1800 over the 2800?


Why should I buy the 2800 over the 1800?



I have this problem too.

I was told by an AT&T nw engineer that you could not put dual wan ports on a 1800 - don't know if its true, but that would stop me from buying them for my remote sites that need redundant isp connections

quoting from the link provided:

10/100 Fast Ethernet (FE) WAN port Provides connection to 10/100BASE-T Ethernet networks. Can be connected to other network devices, such as cable modem, ADSL, and router. Cisco 1801, Cisco 1802, and Cisco 1803 routers have one 10/100 FE WAN port. Cisco 1811 and Cisco 1812 routers have two 10/100 FE WAN ports.

So clearly some of the 1800 support two and some support only one.

Another comparison is that the 1800 fixed configuration routers (1801, 1802, 1803, 1811, 1812, not 1841 or 1861) include built in Ether switch. So you get Ethernet switching and routing in the same box. The 2800 has an optional Ether switch module but none come with built in Ether switch.

I find it interesting that on the 1800 the FastEthernet interfaces are called WAN while on the 2800 the FastEthernet interfaces are called LAN. Same FastEthernet interfaces are WAN or LAN depending on where you are reading. So do not get wrapped up in WAN port or LAN port distinctions.

I fundamentally like the first response which sort of says 2800 is bigger, faster, more capacity, and more expensive. 1800 is smaller, lower capacity, less expensive. That is the important distinction.
