Hi,
I use a 2610 router as ras router and I met with the following problem:
When I ping this router with bigger packets, the speed seems OK.
The speed of modem connection is 33600.
When I use the telnet or any tcp, the speed dramatically decreases.
Here is the configuration of the router.
Can anybody help me?
router#sh run
