I found where the problem is coming, the fastethernet is set while there is no connection to it but transmitting more than the ethernet is transmitting with about 48% while the ethernet is just transmitting just 28 to 30%.

I shutdown the fastethernet and removed its ip, then its stopped dropping/lossing packets, means packet loss is solve. But I still want to be clear with things guys, how can one be good in troubleshooting network problems? any idea please?

Thanks for the assistance essthanzero I will always need your assistance if i have any problem if you wont mind?
