Question : Problem: Cisco 2610 And Cisco 2509 Help

Hi experts,

We have an old Cisco 2509A with 4 modems connected to it that is starting to fail. We have now bought a new cisco 2610 with the 8AM module. When I compare these two routers the old one seems faster. The ping time with the old one to the same subnet is always under 140ms, When I try the new one the first package almost always times out and the rest have 200+ms.

Test done with a 28800 modem.

Any suggestions on what to do?

Under the Line configurations - I see that you are not locking speed with the "speed" command.  It may be that a slower speed is being negotiated during the autoconfigure.  I would try locking the speed at the fastest known rate your modem can handle.  Note that this is not the same as the baud rate so you don't necessarily have to match it up with the "28800" speed of your modem.  Try setting it at 115200 or 57600 first.
