Good day to all I have a problem I have a router mikrotik Hap lite and rb751-2Hnd(tried both), when you configure a pppoe connection, the Internet works the first day, the second begins to grow with 24 ms ping to 1500 - 4500ms (pingou to ya.ru and the router is not overloaded is person 5 max per day), after some time router stop responding to ping at all, but it gets an ip address and other information from the pppoe server (I restarted the connection and the router) , but pings not responding still. The house was connected to another ISP via pppoe also works perfectly. Now is Asus rt-n56u with padavan firmware from running perfectly for a week, ping stable as a power in North Korea :)
Routers are configured through a quick setup in home mode ap. I changed dns servers, it was played with mtu and mru exhibited different values and automatic. Mikrotik needed to hotspota in a cafe. Configuring standard firewall. Maybe someone with something similar faced? Those. support called saying a session is there, everything is fine, call a specialist and go away boy. Sorry for the terrible presentation of the question, a large number of errors and thank you:)
