Cisco 2821 router

I have a Cisco 2821 router, default hardware ports.  I wanted to know if it will support a 200Mbit/s internet connection, both up/down?
I currently have a 100Mbit/s connection and am not sure if 1. it will support 200Mbit/s, do I have to make any config changes for it to pass traffic at 200Mbit/s?

Thanks, Dan

It would appear 100 Mbits is the limit of that router.

I use a Cisco RV325 router and I upgraded to this router because it gives me 900 Mbits/sec internal throughput.

Isn't the RV325 consumer grade?  I need something that is for commercial grade, because I have over 80 users, and some are power users.  If we bump our internet to 200Mbit/s, I need something that is really solid.  I actually also have a RV325 for my 2nd network, but I only have 4 or 5 computers behind that router, so I don't know if it would handle like 70 + users?

What about the 2911, would that work?

RV325 is entry level commercial. But other newer commercial Cisco boxes should have faster throughput. I was just giving an example.
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Here is a Cisco discussion with a graph of various Cisco devices. I am not sure the 2911 will do what you want.
Your ISR 2821 WAN performance you can see here - 87Mb (and that's without any security, QoS etc...)
Cisco ISR G2 router performance - to see what should match your needs - here. In this document are included performance with  NAT + QoS + ACL etc. Looks like you'll need to replace your router.

I'll get the 3845, as that should support up to 245Mbps. I'm assuming that's a bit better than my 2821, right?
DanNetwork EngineerAuthor Commented:
Thanks guys.  I think I'm going to get the 3845, I can get a used one for around $550, which seems reasonable.
JohnBusiness Consultant (Owner)Commented:
Thanks and yes, the 3845 should work.
3845 is 3U size and consume a lot of power .. What about 2821?
Benjamin Van DitmarsSr Network EngineerCommented:
The ISR G2 2921 does 245 mbit and the ISR G2 2951 does 296 mbit. both units are 2U and use much less energy
DanNetwork EngineerAuthor Commented:
I am using the 2821 and it only does 87Mbps.

I need something that can push at least 200 Mbps, both IN/OUT.

Is there any other options?
Benjamin Van DitmarsSr Network EngineerCommented:
The 2821 is not going to do this job for you. the routing engine inside is not fast enough
DanNetwork EngineerAuthor Commented:
Hi Benjamin, yes I know the 2821 can't handle more than 87Mbps.

Is there a more powerful router that is cot effective?
Benjamin Van DitmarsSr Network EngineerCommented:
what is the function of the router. is there one firewall behind it. what is the function of the router ?
maybe we can solve this in another way
DanNetwork EngineerAuthor Commented:
So I have a router, and then behind that I do have a firewall, so I don't need the router to have a firewall.

I just need a router, as I'm not even using the router for VPN, I'm doing VPN on my firewall.

I just have a few ACL's, and basic config on the router.
