New 4431 upload speeds about 10% of norm.

[swicklund]

Replaced old EOS/EOL router with a 4431 with a 100Mbps synchronous connection.  Internet speeds were about 5mbps.  I fixed download speeds by replacing duplex/speed commands with negotiate auto on both ends.  However the issue remains with upload speeds.  The config is below, any help is appreciated.

"Half Duplex"?

And there's your allowed bandwidth goooooone right there.  

Talk to AT&T and ask them if they've hard-coded speed and duplex on their side.  (Be prepared for AT&T to deny anything-and-everything.)  

[swicklund]

I saw the half-duplex but missed the collisions.  ATT "resolved" my ticket but did not note it in any way.  I talked with my boss and just went ahead and set the port to full duplex, speed 100 and that fixed it.
