We recently upgrade our dedicated T1 circuit to a 10Meg Ethernet over cooper circuit. We got an 1841 Integrated Services router to replace our old 2600 router. Our connection speed is slow. I was wondering if my router config is at fault. I have sample of my configuration and a show version. I was hoping someone could make some suggestions.

For starters, try to hook up a single PC directly on the ethernet link instead of the router and see whether the problems are with the router or the line ...
Then check whether you have CEF enabled on the router. Without it, it will be slow as the processor will be doing all the routing and forwarding.
Do you have any access lists configured? Large ACL will also slow down the router.

Guess you can't go with much less than that ... do try to hook up a PC directly and see what speed you can achieve ... CEF is enabled, no NAT, only the 10M on the outside interface is somewhat unusual ... but with a 10M link, I guess it shouldn't matter much ...

ping a website from ur lan, and check there shouldnt be packet drops in communication and latency "TTL" should be no more than 500 ms, if yes then the problem is with the ISP,

Just to mention - is you get 500ms pings to any major website, there's something wrong even if there is no packet loss ... either that, or you have a crappy ISP ...
