Note:
If the VAS 6154 always starts up in WLAN Direct mode and requires mode switch-over as
described above, its startup in WLAN Infrastructure mode was not configured during initial setup.
In this case configure the VAS 6154 to always start in WLAN Infrastructure mode: Access the web
interface and configure accordingly. For details refer to Appendix 1 and Appendix 3b.

If the blue LED continues to flash indefinitely (does not
eventually remain on/flicker and be recognized by ODIS
Service) check the WLAN Infrastructure configurations:
• Remove VAS 61564 from vehicle DLC

Flashing 1Hz

• Follow the instructions in Appendix 1 and Appendix 3b

Perform connection test:
• Remove VAS 61564 from vehicle DLC
• Follow the instructions in Appendix 1 and Appendix 3d

Note:
If a large number of Bluetooth® devices routinely transmit within the dealership WLAN environment,
try activating the 5 GHz frequency range option in the VAS 6154 web interface to avoid interference.

Service Information
Prerequisite:
 The IP address of the dealership’s WLAN access point must be known.
1. From the Windows desktop, click the Windows (Start) icon.
2. In the Search programs and files window, type in: cmd.exe (exactly as illustrated below). Then
(keystroke) Enter.

3. After the command line prompt, type in: ping and the IP address of the access point. (Example
illustrated below.) Then (keystroke) Enter:

A successful access point ping response will show the same number of packets “Received” as were “Sent”
(as illustrated below).

An unsuccessful access point ping response will typically indicate a number of “timed out” requests and
the message: Received = 0.
In this case, check the access point power state, network configuration (correct IP addresses, subnet
masks etc.) and possible access point malfunctions in accordance with the manufacturer instructions.

Appendix 3d – Connection Test
The connection test confirms the VAS 6154 WLAN Infrastructure connectivity on the configured WLAN.
Note:
The connection test only confirms the ability of the VAS 6154 to connect to the WLAN. The test does
not confirm the ability of the VAS 6154 to exchange data with the diagnostic device via the WLAN,
i.e.: data exchange may be blocked by network security measures.
1. Select the DOCKING STATION main category: Retry selection if no connection is made initially.
2. From the WLAN interface test: Infrastructure subcategory, click Run test:

The test takes approx. 90 seconds. Successful test result example:

Service Information
Note:
If the connection test returns a successful result, but the VAS 6154 is still not recognized by
/connects to the diagnostic device when using ODIS service (VAS 6154 connected to vehicle DLC),
refer to Appendix 4 below.
An unsuccessful test result will specify the affected infrastructure entity and reason for failure. In this case,
address and resolve the reason for failure accordingly.
Unsuccessful test result example: No network found, or weak signal with alternative (stronger) networks
found.

Appendix 4 – WLAN Optimizations
If the VAS 6154 is still not recognized by or does not connect to ODIS Service, or established connections
are intermittent or lost during a GFF session, issues that are specific to the dealership network may be the
cause. In these cases, various optimizations can be applied.
