DNS Hijacking attack/Can someone please help me with this

I was wondering if I have become a victim of a possible DNS Hijacking Attack.  I got the DNS Server message below.  My laptop would not connect via wifi.  It has worked flawlessly for over 1 year now and yesterday it would not connect to my router and I kept getting this error message:

"your computer appears to be correctly configured, but the device or resource (DNS server) is not responding

Contact your network administrator or internet service provider (ISP)

Windows can't communicate with the device or resource (DNS server).  The computer or service you are trying to reach might be temporarily unavailable.  If the device or resource is nearby and you have access to it, make sure it is turn on and connected to the network".

I would also like to know is there a known reason why this happens, for example not being able to connect to the server and internet.

However I was able to fix/reconnect to the internet after I pressed the reset button on my router. it is a ARRIS NVG599 router on the AT&T DSL Service.

It sounds more like your router was offline rather than some sort of "attack."

This time it was not my router or Mediacom it was (according to diagnostic test and Norton Notices) IObit Advanced SystemCare had changed my DNS server thus leaving me no intranet connection. I've used IObit along with Norton (yes yes bad bad me) for over 2 years - Norton maybe fifteen years. My intranet kept getting turned off. I play an on line Battlenet game i.e. major data transfer but this was not the problem despite what gamers' say about Norton I have no problem. I got my DNS back and deleted IObit. All good - when I look at Norton notices there are all kinds of attacks especially attempts at my printer (wireless).
