Which router to choose?

Unanswered Question
Mar 7th, 2010

We are looking for a router that support 3 internet connections. All of them are Fastethernet Connections.

I am looking at this part number

2811 w/ AC PWR;2FE;4HWICs;2PVDMs;1NME;2AIMS;IP BASE;64F/256D

What does 4HWIC mean? Does it mean slots only? So I have to purchase 3 1-port Ethernet WICs? Also IP Base does not support VPN, does it?

How about 1841? It only has 2 HWICs. Can I add 1 2-port ethernet WIC and 1 1-port ethernet WIC to support 3 internet connections?

HWIC stands for High speed Wan Interface Card.  Yes, "4HWIC" means the router has 4 HWIC vacant slots available for use.  To be able to use three ADSL you need HWIC-1ADSL.  Please be aware that you need a minimum of IOS version 12.4(4)T.

1841 doesn't come with HWIC-1ADSL.  You are confusing the HWIC-1ADSL cards with on-board Ethernet ports.

On 2811 or 1841, you will have 2 on-board fast ethernet ports and as per your requirement, you would be supporting 3 internet connections.

So I guess you would require in total of 4 Fast ethernet ports: 3 for ISP connections and 1 for inside LAN segment

You can use HWIC-2FE module on one of the slots to gain 2 layer three FE ports. this can be used on either of the routers 2811 or 1841. Decide which one you wanna go for based on Performance, throughput and Cost.

You can refer to the following document for more details about HWIC-2FE:


Hope it helps.

Well first and foremost, PERFORMANCE. ISR-G2's are really 2nd Generation devices and way ahead of ISR's in terms of performance. For detailed comparison, you might wanna look at the datasheets of these routers.
