Sorry for my question, but this is really annoying. My LTE/router is according to the log checking to these two pages all the time: dns.msftncsi.com and www.msftncsi.com (HTTPD). There is no other connection to the router and this is creating significant traffic about 1-2MB a day. As I need my router to send only some small documents (kilobytes) per day, this is really not what I expected, as I have to pay for my traffic. There are several guidelines using internal CLI to shut this dns probe down. But I am not really able to solve it as I do not have any CLI manual for this modem/router. Do you have any experiences with this issue?

Thank you for any help.
