What is the 192.168.l.254 ?

We have an issue in our meteorological station based on CR1000 and connected to WiFi network via NL241 Wireless Network Link Interface. The NL241 is configured in Bridge Mode, with default parameters, while the CR1000 is configured to use a fixed IP address. Signal strength is about -75 dBm

The CR1000 acquires the data every 10 s and send to a FTP server one data tables every 15 min and four data tables every 60 min. It sends also error messages via email, using EmailRelay instruction. Usually the system works fine but occasionally it stops sending email (while file transfer via FTP continues to work fine).
This problem is more frequent during the week, when the wifi network is more busy, than the weekend.

The connection to the data logger via Loggernet is always an available option and it is possible to monitoring the logger activity. However, when there is the failure on email sending it is also impossible to upload any file larger than 960 bytes to the logger (i.e. sending a new program).

Our hypothesis is that EmailRelay function is blocked because the system is unable to receive data strings used in the secure connection, larger than 960 bytes. 192.168.l.254
