Having trouble with TWC Internet connection in my network config

Our Internet speed is supposed to be 50/5.  TWC tech said he tested connection on back of their modem and said speed was 50/5.  We are seeing 6/5.

From the TWC modem cable runs to ASA 5510, then to switch.  Cisco 1720 on same switch. Four servers on same switch.  I connected my laptop to same switch and disconnected switch from rest of network.  Still only get 6/5.

Have swapped out switch, get same results.

Can you put your laptop directly into ASA port? To the same port where the switch is connected and then try once again?

Try setting static speeds and duplex on both sides instead of auto?  Sounds like the Cisco ASA is sensing the port at 10/10.  Also check the cable.

If you can, let us know of the results from "sh int" command.

The ASA inside port was set to full/100.  Outside was set to auto, changed to full/100.  No change.

Also, cannot disconnect ASA today, used in production.  Will be another week before I can disconnect.

Possible the Cisco 1720 is the problem?  Was under impression throughput was 100, but is it less?
Edward ChoManaging Exciting Technology ThingsCommented:
If you have a spare port on the ASA, see if you can run a speed test via that port.

Like I said, also try a different cable.

I removed the Cisco 1720, no change.
Replaced all cables, no change.

Have asked TWC to come out again.

Issue has been resolved.
First removed Cisco 1720 from network.  1720 maximum throughput is less than 5 mbps, which was slowing traffic.
After removing 1720 Internet traffic still slow.  Trouble turned out to be the switch the ASA was connected to evidently was maxed for total throughput (switch was new, 10/100 autosensing).  Changed ASA to different switch (10/100/1000) and speed immediately picked up.

Previous tests did not identify switch because 1720 was slowing traffic, so until 1720 was removed could switch be identified as culprit.
