A WPA2 Enterprise EAP-TLS connection needs to be configured, but no private
key could be found. Save the private key in PEM format under the name
“private.key” together with the XML file or upload it in the web config.
The WiFi data logger is displaying error code E25, what can I do?
Incorrect format of the private.key certificate. Check whether private.key is
available in a PEM or BASE64 format. To do so, open the certificate using a text
editor and check that you can see the string “-----BEGIN CERTIFICATE-----”. If
you cannot see this string, the IT department or the user must explicitly export
the certificate from the Radius server using BASE64, or convert it using openssl.
There must be one certificate only, not a bundle, inside the file.
The WiFi data logger is displaying the error code E26, what can I do?
There are 3 possible reasons for this error:
1 The access point (WLAN router) is outside the wireless range or is
switched off. Check whether the access point is available. If necessary,
change the location of the WiFi data logger.
2 The network name (SSID) stored in the WiFi data logger is incorrect.
Check the network name of the WLAN network. Use the Quick Start
Guide to create a new configuration file with the correct network name
and save this onto the WiFi data logger.
3 The access point of the WLAN network does not use one of the following
encryption methods: WEP, WPA (TKIP), WPA2 (AES, CCMP). Configure
the access point so that one of the supported encryption methods is
used.

with the correct password and save this onto the WiFi data logger.
2 The access point (WLAN router) has a MAC filter or does not permit the
integration of new devices. Check the settings for the access point.
