ICOM Next is a later generation of BMW's Integrated Communication Optical Module hardware. Next A is the main interface between a workshop computer or network and the vehicle; ISTA remains the software used to conduct the service operation.

Hardware
The family guide identifies the Next A diagnostic unit and OBD cable, Next B MOST adapter, Next C legacy vehicle adapter and Next D motorcycle adapter. BMW describes Next A as a protocol converter exchanging data between the tester and vehicle control devices. The guide also documents compatibility with legacy ICOM adapters.
Using and identifying it
Confirm the appropriate diagnostic socket, adapter, cable, software support and interface firmware for the job. A normal fault read and a vehicle programming session may have different requirements. BMW's AOS guide calls for an appropriate external power supply for programming and warns against a wireless link between PC and a J2534 pass-through tool.
The BMW hardware guide contains photographs of the components. Compare the family overview and the earlier A2.
Wi-Fi (WLAN) setupThe BMW-hosted ICOM Next hardware guide documents WLAN on ICOM Next A as an alternative to Ethernet and says the WLAN interface must be configured. Use the following ISTA workflow for supported ICOM A/A2/Next devices; screen labels and available bands can differ with software, firmware and hardware.Connect the ICOM to the vehicle and to the PC or workshop network by Ethernet for initial configuration. The BMW ISPI manual says the ICOM must be connected to a vehicle and on the same network as the configuration computer. Ask the workshop network administrator for the WLAN settings.
In ISTA, open Operations > Connection manager, select the ICOM and choose Configure vehicle interface.
Under Device Configuration, confirm Mode is ISPI Next when using the ISPI Next workflow, then save the change.
Open WLAN Settings. Enter the workshop network’s SSID and security credentials, and choose a mode/band supported by both the ICOM and access point. The Release 1503 ISPI manual lists 802.11n at 2.4 GHz or 5 GHz; use the options shown by the actual device.
Save the WLAN settings, then choose Exit configuration. The ICOM reboots to apply them; the manual says it should reappear in the connection manager after about one minute.Check the WLAN LED: on ICOM Next A, green indicates infrastructure WLAN, yellow indicates ad-hoc, and off indicates no WLAN communication. The ISPI manual also warns that an access-point session timeout can interrupt extended operations; have the network administrator disable that timeout for the ICOM network.Scope: the ISTA path above follows BMW’s documented ISPI workflow. Some third-party guides instead use the ICOM browser configuration page and quote particular addresses or settings. Treat those as model/firmware-specific and confirm the actual interface details for your unit; do not copy sample SSIDs or passwords.Browser setup for WLAN-capable interfacesSome ICOM versions and firmware provide a browser-based configuration page. Use this route only if it is available on your interface; the ISTA Connection Manager steps above remain the documented BMW ISPI workflow. The menu labels and activation steps can differ by device.Connect the ICOM to the vehicle for power and keep a wired Ethernet connection between the ICOM and the configuration PC or workshop network while setting it up.
Run IToolRadar to find the ICOM’s current IP address. In a browser, open http://<current-ICOM-IP>:58000/. The address varies; do not assume an example IP from another setup guide applies to your unit.
Open WLAN Settings. Enter the SSID and password (pre-shared key) for the wireless network the ICOM should join. Select only a security mode and Wi-Fi band supported by both the ICOM and the access point, then choose Save Changes.
Exit configuration if that option is available, or restart the ICOM using the controls for that firmware. Keep the ICOM connected to the vehicle; some vendor guides report that a restart or reconnect is needed before WLAN becomes active.
Connect the diagnostic PC to the same router/access point and check the WLAN indicator and ISTA Connection Manager. On ICOM Next A, BMW documents green for infrastructure WLAN, yellow for ad-hoc, and off for no WLAN communication.Use your own network name and credentials. Seller examples that show a preconfigured router or sample password are demonstrations, not universal ICOM defaults. For long sessions, retain the access-point timeout guidance in the BMW ISPI manual above.
