I would agree, it sounds like a phone line issue. An external of any major brand might help. Having an external with it's own Power, Pump, Controller, and DSP is often helpful in improving or stabilizing a connection. Typically once we determine that it is likely the phone line, we send a test modem out and see if it improves the connection at all. We use two external modems for situations like this, the older USR Sportster 5686-03, and the newer V92 Zoom 3049. The Zooms can be picked up retail at about $66 and they work pretty well. Not sure what an older USR goes for. Have you checked the line to find the Signal to Noise Ratio? Frequency probe levels? http://www.totalscrutinizer.com/ might be something that could help you. Download the demo and email me for the newest beta. It will give you SNR, Freq. Probe Levels, and more. If we can get the data from TS for that user, I should be able to give you some ideas to look at first. -- Adam Barnhill Support Engineer, TotallyFabricated.com Information Technology Engineer, Poplar Bluff Internet, Inc. / Semo.net P.O.

We have had the best luck w/USR5610B modems, their no $15 connextant/lucent but we have a lot of people in the sticks connect much better with them. Timothy C.

When the phone company says they serve that area with a "t1", is that REALLY what they're doing, or are they running a 4-to-1 Multiplexer on a single pair? If that's the case, then no V.90 for sure. I've had a cust in a rural area, all their neighbors get 26400, on his Lucent he'd connect at 44K, but got almost no throughput. Attempts to force a lower baud rate didn't help. Only solution was to replace his modem with a Conexant that only got a 26400 from the start and everything worked peachy. Just my opinion.

(small town - 6500 population - Trumann, AR) Connect speed of 40.something. That same computer when he tries to connect at his house (about 5 miles out of town) will not connect. He has managed to connect a couple of times, but now it will not verify his login at all. His modem is a lucent win modem. It will connect but it will not verify his username and password. And it takes an extremely long time to try to verify his username and password before it fails. The message is usually that the remote computer did not respond. I have tried lowering the baud, but this did not work either. I told him to call the phone company (CenturyTel), which he did. They say that the lines are ok and it must be my equipment. I have taken my laptop out to his house and can connect every time but only at a speed of 20.something. From my house in town my laptop will connect at 48.8. I do not here any static on his line thru the phone, but I do here a small amount of hum. I called my buddy that works for the local phone company and he said that the lines in that area are run to local box and connect back to the co via a t1. He also said they have run a loop test at the customers house and that checks out. 3 out of 4 customers I have in that same area have had the same problems. I do not know what speed the one customer connects at, but he has never called to complain about anything. Could there be something not set right with my chassis? Anyone else had a problem like this? Here are my hardware/software versions. 1 3COM High-Density 24 Channel NAC 3C4 0.49.0 2.1.9 3 3COM High-Density 24 Channel NAC 3C4 0.49.0 2.1.9 4 3COM High-Density 24 Channel NAC 1OQ 0.55.0 2.0.51 16 3COM HiPer ARC NAC 28B 15.0.0 5.0.9 17 3COM Network Management Card with clock 1U600000 6.0 7.1.8 Thanks, and sorry for the long post.
