Router connectivity / QOS Issues

Hello all, First timer here in these forums. :) I am dealing with an issue that we have been back and forth (again and again) with the service provider

on issues where the end users are disconnected if using a PC or experience latency if on a thin client. Here is some of the interface info - any ideas on where to look? Note the high number of drops / errors / collisions? In my research, I am still thinking it is a dirty line?

Any guidance would be greatly appreciated. :)

  1. You will have collisions becuase you have a 10/half connection on the interface E0/0. See if you provide can provided 10/full

  1. It looks like priority queuing is configured, you can starve lower priority queues with this queuing mechanism. Consider changing to LLQ or CBWFQ to avoid this.

  2. Determine if the input drops are continuous or a due to traffic spikes. config "load-interval 30" on e 0/0 so you can see traffic rates averages over a shorter interval - the default of 5 minutes is too long.
