Need router that supports 100 mbps full duplex on the wan

Cogent Communications requires that the WAN port be set to 100 mbps full duplex. I need to find a reasonably priced router that will allow this.

Take your pick. Any modern router meets that criteria.

Not true. The Cisco RV042 has no way to set the WAN port at all.

It will auto negotiate 100 full on both ports. Does Cogent's gear that you're connecting not support auto negotiate?

Seeing as they said to force the settings, I'd guess "no". (WAN circuits rarely connect to a switch, and long-haul gear tends to be very limited in it's abilities; plus there's no way to communicate the link state to both ends, so if one end negotiates something different than the other, the link doesn't work.)

That is correct. Furthermore, Cogent will not honor their SLA unless the router can be set to 100 mbps full duplex.

The company is small - 5 workstations. They do not need a fancy, expensive router otherwise.

Nevermind, the ZyXEL doesn't allow you to manage the speed on the ports...

Carry on...

An ASA isn't a router per say but you can set the speed and duplex on the switchport. It also works well as a firewall. The ASA5505 can be had for a pretty reasonable price.

Another option would be a Cisco 881 which is a router although I don't know if it would be capable of 100 meg throughput.

I have an 861 that handles wirespeed (100Mbps) with some CPU to spare with NAT and a few ACLs. The 881 is pretty much the same silicon under the hood. That being said, i'd still go with an ISR G2 1905 or 1921, overall a much better box.

Thanks all. I'll look into the 861 and 881.

So the 861 is EOL. Looking at the 881 specs, I can't tell for sure that I can set the port to full duplex.

If you don't setup for 100/Full you will get a nice steady stream of errors that do all kinds of bad things to voice traffic. We use Cisco 2811s for Cogent circuits. They are cheap, reliable, and flexible.

Almost every Cisco box that can do 10/100/auto can do full/half/auto. I'm sure there are some exceptions but they are few and far between.

So you're looking for a Cisco Cisco box, or can you live with Cisco Small Business or Linksys by formerly-Cisco-now-soon-to-be-Belkin?

As others have said, Cisco kit running IOS'll allow you to configure the speed / duplex on the layer 3 interfaces to your
heart's content. It just depends how fast your internet pipe to Cogent is, what your technical skill level is, and what
your budget is.

The contradiction you have OP between your desire for a WAN interface that can have its speed / duplex set and this

said by BelowGrand:

The company is small - 5 workstations. They do not need a fancy, expensive router otherwise.

kinda makes me worry... does Cogent offer any options / opinions as to what works, or offer any sort of managed services
for this link?

We have an RV042 now. It does not allow me to configure full duplex. The pipe is not fast, but Cogent insists on 100 MBPS. They will not honor their SLA without this. We'll decide whether to switch to a new provider (which might be less expensive anyway) or replace the router.

Stick a managed switch between your router and cogent. You can set speed and duplex on each port and everyone stays happy.
