32 byte packets = drops & high latency 1500 byte packets = no drops and low latency

Cisco 2900 router on a T1

WIC was replaced at some point by AT&T sending one out and making the site replace it. Don't know about the smart jack.

We isolated our issues down to the WAN side by re-punching at the 66 block & re-terminated or re-punched every LAN jack and connector and replacing all patch cables. Plus we setup continous pings to 15 LAN devices spread-out across the facility and never dropped a packet.

Router is managed by AT&T who's been on-site twice. Tech clears the line and bolts. Fucking AT&T.

I saw this type of behavior before but, it was years ago and I don't remember what it was. It's pissing me off and I wanted to bounce it off other network people to get some ideas to go back at AT&T with.
