I have a MegaFon operator, in order to use the Internet you need to go to the modem settings 19220228.88.1 -> IP -> Firewall -> Mangle tab - press + -> select prerouting and set 65 in the TTL settings. Click Apply and Ok. All. That's the whole setup. More than enough for a layman. The Petra antenna (you will find the manufacturer yourself) was able to catch only 3 Mbps. It is worth noting that Mikrotik was able to catch even lying in the attic (towards the tower), but the speed was not so hot.
