The PNNW.net FAQ is probably the best place to start your quest for help. It was designed to give simple answers and suggestions to those common, known problems we have had experiance in dealing with ourselves.
We are constantly adding and modifying this FAQ and are open to your suggestions for additional info, not already contained within. Email: support@PNNW.net
Jump to the following topics:
- Why is my 28.8 or 33.6 Modem Connecting at 57,600 (or 115,200)?
- I'm using Trumpet Winsock and can't connect?
- What's the best modem init to use when connecting to your POP's?
- My USR Modem frequently disconnects or can't connect?
- I'm using NT 4.0, and get no data transfer?
- Links to Data Sources on 28.8/33.6 fax-modems:
First of all, your modem is NOT communicating with the remote modem at 115,200 bps! What you are seeing is the DTE rate (the speed your PC is talking to your modem) instead of the DCE rate (the speed your modem is talking to the remote modem). What you want to see is the DCE speed -- the communications speed that the two modems negotiate with each other when they CONNECT.
A good solution if you want to see actual connect speeds and other information about data transfer and such, is to use a dilaer/connection diagnostic tool. You can download a couple good shareware programs at TUCOWS or you can purchase a copy of one of the best reporting software apps available... Net Medic by Vital Signs will tell you EVERYTHING you will ever need to know about your connection.

Most, if not all versions of Trumpet winsock, will need a script file to logon to the Internet. Below is a link to two such script files that should work. There is some additional, excellent information for troubleshooting Trumpet Winsock found at our HelpFirst Site.
Please click on one of the links for the script file (basic text file).
Many people experience problems getting or staying connected. Often these problems can be reduced or eliminated by using the proper modem initialization string. It seems that almost every modem brand and model has its own variation of the "Hayes AT Command Set" and "s-register" settings -- there are literally hundreds of variations. Detailed discussion of modem initialization strings is beyond the scope of this page, but in general read your modem documentation carefully, and don't put more into the string than is necessary. As an example, with a Supra on a PC, the string AT&F2 is an adequate initialization string for many users; for a USR modem, AT&F1 is frequently adequate. These two examples demonstrate using a "template" -- a pre-defined set of modem initialization codes which can be invoked with a single command. Please click on this link for some inits we have found helpful for our customers connecting to our POP's.
Some of your users may have some problems connecting or seem to get disconnects. We have found that USR modems have trouble with a compression called LAPM. Until Livingston comes up with a global solution, we have found the best way to solve this probem is to turn off that compression with a modem init string and turn off Data Compression through any other means found in their respective dialer(s). We have found that this works most of the time. Click on this link to view a complete listing of known, helpful inits, including on for USR's having these reported difficulties.
Some of your NT customers may get no data transfer when connected. You'll need to have them simply uncheck "Use IP header compression" in DialUp Networking/RAS. That is the fool-proof fix! You can find that check box under edit phone book entry, then servers, and then TCP/IP settings. Believe it or not, its that simple and has worked time-and-time again!
