Intermittent short ping spikes

[JBD123]

Hi, for the past few days I've been experiencing intermittent ping spikes. Have been running "ping google.com -t" for a while, and the spikes seem to last between 5-30 seconds, with 5-60 seconds between them. The normal ping is around 20-30, and spikes range from 200 to 500. I. The spikes are present on multiple devices, over ethernet and 2.4+5Ghz wireless, and are even evident when pinging google directly from the router. According to my ISP there is no issues with the modem or lines. I've tried resetting and checking for firmware updates for both the modem and router. Had no issues for over a year.
Hardware:
Router: Asus Rt-N56U
Modem: Netgear CG3100D-2 (connected to Telstra Ultimate Cable)
Misc: Netgear WN2500RP range extender and Netcomm NP506 Powerline adapters are also present in the network.

Thanks in advance for any suggestions.

You need to test from a directly wired pc just to be sure.

Run tracert to google. Now if you actually have the netgear in bridge mode then it will be transparent.

You want to open multiple cmd windows and run continous ping to the first couple of hops . The first will be your asus, the second may or may not be your netgear, the third will be the ISP first router....unless it is the second hop.

What your goal is to see where the problem starts. If you see issues in the first hop then your router has a problem. The more common one is ISP router. This represents the modem in your house as well as all the wiring between you and the ISP. It is seldom the ISP router.

You modem may also have screens that show the signal levels which you can search for what mean. The are normally some DB value. You will need to read the guides since the number that is considered good varies based on the type of cable system you are connected to.

Still pretty much if you see error in the connection to the ISP they need to come out and find it for you.

Things past the first ISP router represent issues in the ISP network.


You can try tools like pathping but since you know how to do this manually with actual ping commands you get somewhat better results but the pathping would be good to email to the ISP if you can get it to show the same problem.

Thanks for that suggestion. It seems as though the latency spikes aren't occurring because of anything on my network. Was able to convince the ISP to come out tomorrow to check the lines. Hoping it will be an easy fix. Thanks again!
