[BVARC] For JP - Re: ethernet question

Open a command prompt on your windows PC

Type: ping 4.2.2.2 -t
Press enter

The time in milliseconds should be stable around 15-25ms 

If you get REQUEST TIMED OUT that means your dropping packets

If you have high ping times, 50, 100, 200, 500, etc… that can mean several things

First make sure no one streaming any videos. If your network is not used and you have fluctuations in times make sure you are not wireless. Wireless is awesome but stability cannot adequately be measured due to so many different variables with radio waves

If you still have fluctuations and dropping packets make sure that you have QoS turned off in your router

If you still have fluctuations power cycle your modem and router (if they are separate boxes).  

If you still have fluctuations call your ISP and tell them that you have high ping times and dropping packets. They will check the integrity of your line. Do not let them off of the hook. Let them know that you would like to have a technician visit if they can’t figure it out remotely

If you use ISP provided equipment replace it. Their hardware is recycled from god knows how many times and in my opinion pieces of junk 

To get the ping to stop hit ctrl + c on the keyboard

To start it again hit the up arrow, you can backtrack through the history of commands in the CMD session, and press enter to start it or run it again

To get out of the command window type exit and press enter

I used to be a small voltage tech for the cable company and I did a lot of cat5-6 installs for other jobs and almost never used shielded Ethernet. I’ve been told that it doesn’t matter but I’m having my doubts lately.  I am suspecting that my HF signals are interfering with my networking as well. It can certainly knock the wireless router out if commission.  I’m thinking of replacing every networking cable with shielded cat6.

But  I am now seeing error messages indicating short intermittent sequence errors (dropped packets I suppose you would call it) between the radio and the computer. As you would expect, the audio drops out when the errors occur.

Next step in the process was to reconnect the computer and the radio to the switch, but remove the ethernet surge protector from the run between the switch and the radio. That made no difference and the errors resumed. Now I figure it's got to be bad ethernet cable or the switch needs to be replaced.
