Connecting an ethernet switch to a router

After some googling today, I learnt that an ethernet switch must be connect to a router, and not the other way round.

Yet this configuration has worked for me for the past month or so. Today, it suddenly failed and I am unable to use my ethernet devices with my wifi router turned on at the same time.

Due to the way the CAT cables in my house is hidden, I am unable to pull a CAT5 cable from the wifi router back to where the ethernet switch is located.

My question is:

1) Why did my configuration suddenly stopped working when it did before? Did the ISP do anything?
2) Since I can't pull a wire back, can I get a second cheap router and connect the wifi router and ethernet switch back to it? If so, what should I get? (Currently on a 300Mbps Viewquest plan)

Too little info as nobody can give you a proper answer.

Which ISP, plan, Router, ONT / ONR, etc.

A diagram of your layout on the connection to various devices.

Normally cable layout should not be an issue.

The issue lies in how your connection is and there are many reason for the failures.

A detail layout would be better for anyone to advice you further..
