T1 Download speed slower than upload

[bizman]

We have a Netvanta 3430 using a T1 line with PPP but during the day we are experiencing slower download speeds (about half) than upload speeds, which are about normal.  If you run a ping you will see "request timed out" frequently with an average latency of about 112 ms.  Not sure if we are dropping packets.  I do not see any errors in the "show interfaces" results (see incoming ftp directory for files: show-interfaces-gate-11-12-14 and config-gate-11-12-14).  Not sure if it is the router, network, or T1 line.

I am looking for some help with where to start to troubleshoot the problem.

Thankx

All a ping will tell you is path connectivity and if there is an issue on the path, it doesn't tell you WHERE the issue is on the path. You should try a trace route instead of a ping. It will show you where the issue is along the path.

I found the problem.  It was heavy internet traffic from streaming applications that was eating up all the bandwidth.  The router and network are fine.
