Ping stops when there is big packet loss

my first post here.
I made an script that provide reports of my network every 5 minutes. The script is simple and is working fine except when there is issues in my network. The script is running in Ubuntu Server 18.04.
My line for the Ping command is:
ping -w 300 192.168.1.216
The issue consist when I am having packet losses, ping stop immediately an doesn't finish the 300 seconds (5 minutes) run. I checked online and everywhere but I haven't been able to find a solution to make the ping keep running when there are lost packets. This is an example:
ping -w 300 192.168.1.216
PING 192.168.1.216 (192.168.1.216) 56(84) bytes of data.

64 bytes from 192.168.1.216: icmp_seq=2 ttl=128 time=4.14 ms

--- 192.168.1.216 ping statistics ---
33 packets transmitted, 5 received, +3 errors, 84% packet loss, time 32657ms
rtt min/avg/max/mdev = 2.295/20.738/40.659/16.379 ms, pipe 4
Thanks.
EDIT REASON: Add full script code.
Full script code:
Location="XXX"
host="192.168.6.1"
while true
do
result=$(ping -w 300 -q $host)
sendemail
-f "xxxx@gmail.com"
-u "XXX 5 Minutes Network Report"
-t "pingreport@gmail.com"
-s "smtp.gmail.com:587"
-o tls=yes
-xu "xxxx@gmail.com"
-xp "password"
-m "$result"
done
This is to check the status of our VPN. Like I said is a very simple script. I am using the ping -c 1 as suggested for an emergency one that will let us know if there is connectivity issues in the VPN as soon as possible.

Welcome to Ask Ubuntu. I don't understand what you're trying to do, but the-w
appears to be doing what it should as theman ping
states "it waits either for deadline expire or until count probes are answered or for some error notification from network." - ie. it's stopping because last condition is reached as I understand your question. When I've had to do similar to you, I sent a singleping -c 1
& then processed according to error.codeerr1721=$?
in subsequent lines.

All that I need is to have a ping running for 300/3600/86400 seconds, that is why I used the -w. What I need is a way that ping doesn't stop when there are network errors when using the -w or another way to make sure it runs for the specific amount of time disregarding network errors, packet lost etc.

I would consider changing your script to run ping -c 1 <ip-address>
every five minutes, instead of relying on the ping
binary to provide that behavior. Then you can also check the return status ($?
) to determine if it succeeded or failed.
It would be helpful if you also post your script, so that the context of your problem can be more easily understood.
