Search for free Wi-Fi channels
(using the example of a free program for Android OS - Wifi Analyzer)

In most cases, to work with the ScanDoc scanner, the default Wi-Fi settings are sufficient, however, Wi-Fi signal may be lost or the connection speed may be slow.

Symptoms by which you can determine that Wi-Fi connection disappears due to congestion in channels:

A common problem is that the scanner uses a Wi-Fi network of the same channel that is used by other devices nearby. A universal solution: change the channel on which the scanner works (most often, users leave the Auto value, which is set in the default settings).

How to find a free Wi-Fi channel

If you have an Android phone or tablet, download the free Wifi Analyzer app from the Google Play.

Launch the application, in the main window of the program you will see a graph on which wireless networks with reception levels and channels on which they work will be displayed.

Wifi analyzer menu view visible networks Wifi Analyzer flipping a window to the left (swipe) Wifi Analyzer Channel Rating

In the example, you can see that the QUANTEX network (channel 13) intersects with another FREE network (channel 11). However, there are free channels on the left side and in the middle of the range.

Scrolling to the left of the program screen you can see the "rating" of channels (the more stars, the freer the channel).

In our example, the 1st or 8th channels turned out to be free (on these channels the scanner will work faster and without failures).

Change Wi-Fi channel

  1. Connect the scanner to the OBD-II connector of the car.
  2. Connect to the adapter via the Wi-Fi wireless network on your computer / laptop using a password (if your scanner has serial number s / n: 006060, then the connection will be called S6060, and the password for it will be scandoc6060).
  3. Go to the settings of the Wi-Fi module. To do this, type in the browser: 192.168.1.3
