Test ping google.com /t run in Command Promp has too High max ping 215 ms about to lose my workfromhome job

My job is asking me to run "ping google.com /t" for one full hour on command prompt. I keep on getting a result of Maximum ping = 215 ms. After doing this test about 20 times I still keep getting this result.

A tech changed my coaxial cables, splitters, test my apartment internet, modem ethernet, building internet administration and did NOT find any disruption or interruption. The tech kept showing me his positive results, but after I redid the ping google.com /t test my maximum spike after an hour was 215 ms.

We tried troubleshooting with ping from Amazon, we tried with a brand new pc bought yesterday and the maxed ping was the same.

I have CRITICAL logs such as SYNC timing synchronization, no ranging response received all over my event logs.

I changed my velocity to 1gb now my internet is slower. I need help.

That sounds like a problem with the link between your modem or gateway and Comcast's network. Network connection problems are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power. 

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway (from http://192.168.100.1 or http://10.0.0.1):

  • model number
  • uptime
  • downstream: power levels, SNR (or MER), and error counts for all channels
  • upstream: power levels for all channels
  • event log, if available (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)

Copy and pasted text is preferred over images. Be aware that, if you post any images, your message will be made Private for a time, as all images must be approved by the Forum Moderators before the messages containing them become generally visible.

If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit (approx $100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.
