Download speed keeps fluctuating with only mikrotik connection

RouterOS General
1

Hello everyone,

I am using Mikrotik RB3011 , And My internet connection comes from my isp modem(bridge mod) to mikrotik router.

I have set up the mikrotik with quick set up mode without default config. And i am able to connect internet with lan port.

But, speedof.me gives error, speedtest.net does not work properly. Also during downloading process speed goes climax first and then goes down to nearly 0 mbps (this cycle repeats during downloading)
This problem does not occur while i connect the my main modem with a router mode

Any idea what is behind the problem ?

Hi serkand93

Keep your modem in router mode, and just enable DMZ on your modem (should be in security or port settings). This will allow you to use all the functions you need from the mikrotik without using ppoe-out.
All requests will then be handled by the mikrotik, the modem just passes everything along.

Enjoy routing

What is the relation to PPPoE?

See the ether1 torch if you are not part of ddos dns attack because you are missing firewall rules… You shoud not expose unprotected device to Internet.
