Ping response stable with occasional extreme jumps, please help!

Hi, I am a work at home customer service agent and my connection started causing system issues yesterday that may cost my job if I can't resolve right away.

My employer uses Citrix, I've been 50+ hrs into training with no connection issues and then they began. About every 20 minutes my system would alert me that I'd lost connection. It seems the drop in connection was brief each time lasting less than 2 minutes but takes 15 mins to log back into their system anytime you're logged out so you can see why this is a real problem.

I was sent to the IT department and I passed the brief connection tests every time. 0% packet loss and latency around 30ms. But when pinging over a longer period of time, latency and packet loss was occuring.. each time very briefly but somewhat extremely. They did these tests remotely by controlling my screen and advised it was definitely a issue with my local network or isp.

I called isp after my job forced me to clock out and get resolved, and isp was no help.. so ive been reading up and troubleshooting myself. I can do a 1000 line ping test and lose 2 out of 1000 packets or up to 5.. ive repeated the test dozens of times. I'm so stressed because likely if I don't have my connection causing less interruptions by Monday I could become unemployed. 🙁

On a 1000 line ping test, at some point in the test it will lose a couple packets and about 4 to 10 successive lines will return high response times then entirely subside. High like anywhere from 250 to 1200ms response. I'm very confused because these spikes are few and short lived, yet persistent since yesterday. And if they're say 1000ms response for 10 lines then back to 12ms to 18ms the rest, why am I losing connection to their network altogether.

Realistically, if this is something the isp will need to correct, I'm going to be jobless. If I miss more than 6 more hours of training I'm out. I've worked with this company (employer) before back in Fall of 2017 for 4 months on same virtual system, same computer, with same isp and had zero issues.

I've done 1000, 3500, 5000 line ping tests all last night and now 15+ hours today obsessively looking for patterns or any changes. I've noticed none. I do have some 1000 line ping tests where the highest response time returned or maximum was say 140ms.. but always 2 to 5 packets lossed out of every 1000. Average response time remains less than 35ms. Regardless how many pings it seems.

What does the issue sound like it could be? Why is it wonderful response time 99% of the time in every test then these brief but huge fluctuations? Does it sound like a modem/router issue or cable? Could traffic cause this? Do you think it'll pass on it's own? Please I need help any guidance would be greatly appreciated.. thank you!
 
You have to do more detailed testing. Pinging some ip on the internet just means there is some device in the path causing a issue but it give you no clue if it is your house. some ISP device or maybe even the remote servers ISP.

You an try pathping but it may not show what you need since it does not run long enough. You likely will need to do it all manually. What is key is to ping your router, the first ISP router in the path and then maybe the final node. If your router shows issues then it is something in your house. If that is ok but the first ISP router shows issues then it is likely the connection to your house. If both those are good you can continue ping other nodes but if for example you find there is a problem in another ISP what can you possibly do. They will not accept your calls because you are not their actual customer.
 


Thanks so much for replying. I'm currently reading up online on how to do such tests so I can try as you advised. So I understand that pinging a ip doesn't help pin-point at which level the disruption is occurring, but what can be discerned fromthe pattern? If it's wiring, isn't it likely to not perform well 99% of the time as it performs now.. because this is so random?

A 1000 line ping test for example will get a response time of 14 to 21 ms for 400 successive pings, then 1 request timed out, then 14 to 21 ms for 300 successive pings, then say 800 to 1200ms response on a dozen successive pings, then 14 to 21 ms for the last 288 successive pings. (an actual test result) Every test is very similar in pattern.

Could a modem or wiring issue work almost perfectly most of the time and suddenly, but briefly, have high latency? That's what doesn't make sense to me. I admit I'm not technical at all, but it sounds like a traffic/congestion issue would fit the behavior pattern best.. but then again, I know nothing about how hardware operates so I may be entirely wrong.. that's why I'm asking here.

Does the pattern suggest anything to you while I work towards doing the other ping exercises you suggested in the meantime?
