Slow Web Traffic Cisco 1721 1

[Rastor]

I am getting a significant lag, or delay, in getting to ALL web pages from my network to our T1 Line. This is a new Cisco 1721 and these problems persist whether I have/use access lists (firewall conf) or not. Any suggestions or ideas to track this down. Here is my config file that was "suggested" by my ISP, although they have never worked with a Cisco 1721 before. Previous router (Bay Networks 1000) failed and this was similar configuration.(IP Numbers have been changed to protect the innocent)

PLEASE HELP....

Can you give us the show int on this router, and does this have one of the internal CSU/DSU cards? show service-module
could really help too.

I'll make the assumption that you verified it wasn't some other kind of problem IE cabling, or lag with DNS resolution, etc.

I see a few things that I'd check out. Why are you connected to the WAN via a half-duplex connection? If you can bump that up to full-duplex with your carrier, then I'd suggest you do so. That will help a lot.

The second thing I'd check would be the auto setting you have on your LAN interface. Is this connected to a switch or hub? Either way, I'd hard code this link. Auto negotiation is horrible. Use full-duplex speed 100 if you can. If not, find the setting that best works for you. Auto is not the way to go. Try those out and see how your network responds.
