Re: High ping spikes / jitter. Speed is normal.

The 12ms spike is a little odd but typical for a Hitron modem.  I didn't see anything like that from a pingplotter test that I ran.  Did you have more than one device connected to the modem when you ran that test?  If so, then that spike would make sense as it could be caused by another device.  If nothing else was connected, then you have to look at what else might have been running on the pc when you ran that test.  There are a number of applications that call home looking for updates.  Windows runs its own connectivity test by pinging a Microsoft server.  That test result is used to show you if the pc has internet connectivity or not.  Its pretty difficult these days to run a ping test without the possibility of another application causing problems with the results at some point.

Re: High ping spikes / jitter. Speed is normal.

Why can't I get my jitter to drop to 2 ms I'm always in the range of 4ms - 9ms , seen some speed results from other users with low jitter is there something I can do to lower it or jitter tests besides the Rogers speed test ?

Re: High ping spikes / jitter. Speed is normal.

What are your power savings settings on the laptop, are they enabled or disabled?  You would have to step thru the power savings plan or settings to check each one.
