It looks like the Wi-Fi connection drops packets once in a while. This is normal if there's anything in the direct path between the antenna and the station. Only you (and probably your ISP) knows about your setup, the location of the station, etc.
Pings to your ISP should stay relatively constant, even after hundreds of them. I downloaded HSLAB Ping and I disconnected my Internet connection to see what would happen. The time shot up to over 2 million as each ping timed out. My conclusion is that you're not dropping packets, but you get a reply back in no time and that isn't possible over a WAN connection.
What happens if you execute ping -t to your ISP? Are the results similar to what you've witnessed with HSLAB Ping?
but i'm pinging their website, i'm not sure how else to ping my isp
should i try pathping getaway test?
You could use the second IP address returned by the tracert. That's the shortest path betwen your system and your ISP and packets shouldn't be dropped. That still doesn't explain why HSLAB Ping sometimes returns 0ms when pinging an Internet address. If I were you, I'd use the ping results when talking to my ISP (unless they're also interested in the HSLAB Ping results).
started pinging with HSLAB and plugged the cable off after a few secs
it immediately stopped pinging and said "unknown host google.com"
Instead of a host name, ping the second IP address returned by tracert. Losing .5 to 1% packets is acceptable because that type of traffic is not guaranteed. Your issue is caused by something else and I believe that the 0ms detected by HSLAB is not normal.
