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:
    IP adress
  4. In Radio channel: Select a free channel number from the list (in our example 1 or 8)
  5. Click the Save Changes button. The module will reboot.

Possible issues on mobile devices

Disabling Wi-Fi Assistant

Many smartphones have automatic selection of the best network enabled by default. In different versions of Android and in different assemblies, it is called differently, but most often it is called "Wi-Fi Assistant".

If the connection quality is poor, Wi-Fi Assistant switches your device to other available Wi-Fi networks.

For example, you have a Wi-Fi network with Internet access. When connected to the ScanDoc scanner network, the smartphone does not have Internet access and the Wi-Fi assistant automatically switches to another network that has Internet access. In this case, you will see a message in the ScanDoc program: "No communication with scanner"

You can turn off the Wi-Fi assistant in the Wi-Fi networks settings on your smartphone.

In different builds of Android, the Wi-Fi assistant may be called differently and located in different menu items. Below we have presented some options for finding it in popular Android shells.
