Important Wireless Utilities for MCA Bus with Ethernet Adapter: Computers with an MCA bus and an Ethernet adapter may lock up if the Wireless 'Utilities diskette' is booted when the Ethernet cable is not present or unplugged. A specific message identifies the problem (Code 06421 referring to Ethernet cable unplugged). Once the cable is plugged back in, the 'Utilities diskette' works properly. 2. If the workstation has a PCMCIA Type II slot and you have problems when booting the 'Utilities diskette', you would need to modify your 'Utilities diskette' CONFIG.SYS file to call DOS Card and Socket Services support. This may be the case if your PCMCIA machine does not have an INTEL 82365SL or compatible port controller. The following are samples from the CONFIG.SYS file: DEVICE=C:\IBMDSS 2.SYS DEVICE=C:\IBMDOSCS.SYS DEVICE=C:\DICRMU 2.SYS DEVICE=C:\$ICPMDOS.SYS 3. Select Diagnostics Utilities from the main menu, wait for the diagnostics to complete and follow the recommended action. Troubleshooting Wireless Network Problems If you are experiencing wireless network problems and tests of the adapter and radio are OK (through diagnostics from the 'Utilities diskette'), you might have a wireless software problem (such as product installation, configuration) or a networking problem. The Installing and Operating Your Network manual supplied with the product contains a troubleshooting appendix with the following specific sections: Base or NAP station initialization failure, Base status is 'Not Ready' at the NAP, The NAP application is not available, OS/2 bridge does not operate, Data exchange problems through OS/2 bridged base, Workstation registration problems (all red RSSI), Communication problems when using 3270 emulation, Workstation performance problems, Network management does not operate (NetView 6000, NMS,WNM). 244 IBM PC 300/700, IntelliStation Series HMM
