LAN issues - Need to verify that this is a Switch problem !

We have an important issue here at office with our LAN. We get pings off, some internet cuts and other small issues that become unstable our internet conection.

Since we have a NAS, 2 Gigabit switches, a router, 1.000MBPS symmetric connection with optic fiber and fixed IP address and we're getting backups from our OnLine servers and so, we have unstable connection right now.

Probably, problem is with our main gigabit switch, but need to verify and identify the issue, maybe is from our synology DS1512+ NAS ... maybe not.

See screenshots to understand. Aleatory ping and other issues.

Please, very skilled gurus in networking !

I will require to talk via [Removed for encouraging offsite communication which is against our Terms and Conditions -Section 13:Communication With Other Users], and u'll see my screen via anydesk, no time to chat on a text window ......
