Kind time of days. The situation is that: in my house there is no possibility to connect the cable Internet, use the modem 4g from Yota. It has been bought less year back and worked perfectly well, but about one month periodic failures in operation back began. For example. It can ideally work couple of days, but then the floor of day can not start up on any sites with errors ERR NAME NOT RESOLVED, DNS PROBE FINISHED NO INTERNET. Subtracted that it like a problem with DNS servers, but reset of cache DNS, DNS Google/jandeksa servers did not help in a solution of a problem. Errors arise only in browsers, for example, the same YouTube through application on a pad works.
