A new ISP, MidAmerica Net, recently began offering a dialup number (just a virtual pop) in the DuQuoin, IL area which is local LD to me, so I decided to try them.

Well, so far my experience has been less than pleasant. I get low download speeds and ping times between 300 and 1000ms. What's maddening is that I ping an average of 82-96ms to my ISP's Portmaster, but around 500ms average to the first hop outside of my ISP, which is a UUnet ATM relay in Chicago, IL, but I've had people that I know who have cable ping the same hop and get 30-50ms to it. pings 30ms to the hop! I've done speed tests using and my throughput is around 32Kbps down, 21 up despite my 45,333bps connection!

I decided to check my diag screens. Richard, please tell me you have a solution to this nonsense. Otherwise, I'm out $20. :(

Your RTD (round trip delay) indicates you're being routed to your ISP in another city, etc. While online click start, run. Type command. On screen, type tracert and hit enter. Be sure to have a space between tracert and You can type any address here. Note the hops and time it takes for each hop. Save and give a copy to your ISP - they'll want to know where the bogs are (they probably already do). If the ISP has another #, try it and see how performance goes.

That's why I said the number is a Virtual POP. I'm aware it's being routed to another city. Marion, IL to be exact.

I've already thought of sending a screenie, but if they're anything like all of the other ISPs around here, they probably don't give a damn.

The pings you get on a broadband connection versus dial-up connection to the first few hops (sorry) are like comparing traveling by foot and traveling by jet.
This is normal.

The first few hops on dialup may be over 100ms but shouldn't be much above 200ms - if so, it would indicate problem with the ISPs connectivity to the backbone, or too many users for the pipe size they have.

It appears to me that you have a very marginal line (or the ISP's facilities providers has very poor interconnection to your local telco); specifically the 3750 value of y11 is dangerously close to 50; the problem appears to be the gain overall - ie, the receive levels at all frequencies are way too low (higher number = lower level ).
