This page provides information about troubleshooting all types of adapter. It consists of the following sections:
If your Madge adapter is not working properly, do the following:
Check that the adapter is correctly seated in the computer's expansion slot
Ensure you have set the adapter to the correct ring speed. It must match the speed of the network. You can set the ring speed using Madge Assist (for details, see About Assist)
For ISA non-PnP adapters, ensure you have configured the adapter to use free resources. Use Madge Assist to determine used resources
If your adapter is a PCI adapter, ensure the adapter is in the PCI slot nearest to the motherboard
Check that the cable to your LAN is correctly and securely attached to the adapter
Run the diagnostics and configuration program, Madge Assist. If the adapter fails a diagnostics test, reconfigure the adapter and run Madge Assist again
If the adapter passes the diagnostics test, check the software installation. In particular, check that you have followed the correct procedure for your adapter and your particular environment, see Installing Drivers and Driver Installation Troubleshooting
Check that you are using the very latest driver. See the Madge Networks web site (http://www.madge.com/) for the latest software information.
Try to isolate the problem to a particular component, for example, test the adapter with an alternative cable, network port, or computer
Ensure the computer is running the latest BIOS
All PCI, PCMCIA, CardBus, and PnP adapters are automatically assigned a free interrupt by the system's BIOS. For ISA non-PnP adapters, ensure that there is no conflict with interrupts used by anything else in the computer.
If you are using an adapter in a Novell server, avoid interrupt 15.
You have to set the DMA channel for the AT Plus and the AT PnP in non-PnP mode. (For more information see the relevant Driver Configuration page.) You cannot set the DMA channel for PCI and EISA adapters.
If your adapter is not working, it may be due to its mode of operation. Use Madge Assist to change the mode of operation. Below are some suggestions, try these if they are appropriate to your adapter type:
Try the adapter in each mode of data transfer, for example change it from DMA to PIO or from 16-bit to 32-bit
Try the adapter in PnP or non-PnP mode
Bus width can be either 8-bit or 16-bit (bus width sets the number of bits involved in a single data transfer
Bus timing can be either normal or alternative. Alternative bus timing may solve problems on older computers
Bus timing can also be either synchronous or asynchronous. Set this to asynchronous if you are having problems with an older computer
If you have changed any of the hardware switches on the AT Plus, run Madge Assist (see About Assist). The AT Plus Ringnode is disabled until you do so.
If you have an ISA Client PnP or an AT PnP adapter and an older sound card in your computer and Assist cannot detect your adapter, reserve I/O ranges 220 and A20 and reboot your computer.
Only the most recent versions of memory managers are designed to handle PCI computers that are connected to Local Area Networks. If you are using a memory manager and you have problems loading the network drivers, you may need to update the memory manager (for details, contact your computer supplier). If you normally use EMM386, we recommend version 4.49 (or later). This is the version that is shipped with MS-DOS version 6.22 which is available from Microsoft on the Compuserve Forum.
If, after trying the suggestions on this page, you cannot get your Madge adapter to function correctly, contact your supplier or Madge Technical Support.
