RB2011: Thought there was an outage but my router is slow?

Here’s my current setup:

So my Internet connection started getting slow. At times it wouldn’t work at all. I looked to see if there were any outages with Timewarner (my ISP) but there were none. Over the next few days, the problem persisted so I temporarily swapped out my Mikrotik RB2011 for my old consumer-grade router and everything started running MUCH faster. This setup has been running without a problem for several months now…

Are there things you all can suggest for me to look into with the RB? Maybe I need a firmware update or sort sort of buffer filled up? Thanks in advance!

You can try doing ros update and furmware update.
Also you can try changing the way the router has been setup.
