Slow (Internet) download performance on C871 Router

We use a C871 Router for an Internet-connection. The Internet connection by de Router is working fine, but downloading a file from the Internet over the Router gives a very slow speed (3KByte/s instead of 1024KByte/s)

Connecting a PC on the Internet-connection of the Router, gives a good speed.

I use an other Router (same config), but same poor result.

I upgrade the IOS, but without positive result.

What could be wrong?

See attachments for details....

Thans!

first you wrote:

i think you mean:

3KByte/s instead of 1024Kbits/s

because when the PC makes a download it shows speed as Byte/s but the internet speed is in bit/s. so 3KByte=24Kbit.

this is still small. make sure your wan bandwidth is not full. use some SNMP software like PRTG. may be many users are making download. if this does not help

then check for dropped paquets.

Thans for the response.

With the connection is notting wrong.

I think there is something wrong with the Router config.

But I don't no what?

Hi,

I think when you configured the router the first time you do not have to erase the "startup-config" and reload the router.

Hi,

Do you mean that I have to delete the "startup-config"?

Has this something to do with the 'running config' (see attachment)?

Thanks!
