It can be noticed that all requests are sent to the equipment responsible for Internet connection.
5. Then enter ping < DNS_server_address>. For Gars Telecom clients the DNS server addresses are 220.127.116.11 and 18.104.22.168.
6. Run command Ping 22.214.171.124, and in case DNS responds, apply control test: ping www.ya.ru. If after running ping command, we receive “Response from…”, there’s no problem with internet access.

7. To enable/disable “Offline profile” in Internet Explorer, open Tools tab and check whether there’s a tick mark next to the option. To check proxy settings, open Tools and select Internet options.
Then follow to Properties and click Network Preferences. In the appeared window check the tick marks and remove those that are not needed

On the screen that comes up, choose Advanced panel. Open Network tab and click Settings…. In Connection Settings dialog choose ”No Proxy”.
