You've made a couple of posts, that makes it sound like you aren't getting the bandwidth you're expecting. I think it would be best for you to start a new thread following the instructions for posting speed test results. That way, you can get some help specific for your case.
I do make zoom calls and have been able to use video, though I do generally dial in over the phone for audio. There are many variables that affect the performance you are getting, and following the instructions here, will get you help, but ranting on an existing thread likely won't.
It's been a while since we last heard from you, so we will close this thread. If you still have concerns, please start a new thread and include a detailed explanation so we can better assist you.
