Connection with the "guest" W-Lan

If a WPS connection with the WLAN router is not possible or desired, then there is the possibility to connect
Liquid-Check to a guest (Gast) WLAN. The following connection parameters are already preset in the deli-
very state: Wi-Fi Name (SSID): 

Gast

 , Wi-Fi Password: 

12345678

Therefore, you must configure a Wi-Fi router with these parameters, then Liquid-Check automatically
connects to the network after plugging in the power supply. Now also connect your mobile phone to the Wi-Fi
"Guest" . You can then access the Liquid-Check setting menu via the mobile phone's web browser and
manually set and save the desired connection data to your Wi-Fi router.

Instead of providing the WLAN via a router, a mobile phone can also be used, with which one unlocks a
WLAN for other devices via the function "personal hotspot" (iPhone) or "Temobile hotspot" (Andriod).

Example setting on an Android phone
Below is a short Step by Step guide to activate the Wi-Fi hotspot on your phone.

1.

Settings
Symbol „Gearwheel“  icon or simply pull down the top of the image on the right

2.

More
Select „Tet mobile Hotspot“

3.

WLAN Hotspot
Set up Wi-Fi hotspot: network name: Gast, password: 12345678, security: WPA2

Now Liquid-Check can log in to the Wi-Fi of the mobile phone and gets a corresponding IP address.

Note for iPhone: 

Set the iPhone Name under <settings/general/info> temporarily to „Gast“

Note:

 If other connection data is already stored in the device, liquid check can be reset to the connection

parameters set in the delivery state. Pressing the WPS button (> 10 sec.) to set the connection parameters in
the delivery state.

Connecting to the Liquid Check
After successful WPS or guest (Gast) login, you can connect to the web interface of the Liquid-Check via a
popular internet browser (e.g. Goggle-Chrom, Firefox, MS-Edge, Opera, Safari). If your router supports a
name resolution such as the Fritz-Box 7390 then you can connect directly to the following input:

http://liquid-check

If you cannot connect by name, you have the option to display the IP address on the liquid check. To do this,
press the WPS button (button behind the hole) on the liquid check only shortly. The IP-Adr.
enter in the browser search box: e.g. 

http://192.168.x.x

Note

A prerequisite for both connection variants is that the router assigns the IP address via DHCP. This type of
address assignment is usually the default and can only be changed by manually changing the router.

In order for other WLAN devices to connect to a mobile phone or tablet PC with Liquid Check, for example,
the router must allow wi-Fi devices to connect to each other and also allow new Wi-Fi devices.
For example, for a Fritz box, this option is enabled by default. You can find the setting there under Wi-Fi/Se-
curity

(The displayed WLAN devices are allo-
wed to communicate with each other)
(Allow all new Wi-Fi devices)

The guest Wi-Fi may have its own radio button to activate these functions.
