I found this really interesting problem with my network that I cannot fix. My ISP is Rogers (Canada) and their lovely tech team have not been able to even notice that my network has an issue. This is my problem: When I game online there is significant rubber band and random intervals (different games different regions) When I test in pingtestDOTnet i get an average of 50-60 ping and a range of 18 to 59 jitter! (yea jitter is bad this is bad) What test I have done: Almost every kind of test I have done and everything points to the router/modem combo. I tested a cat5 cable and pinged 192.168.0.1 from my computer 192.168.0.10 and the results were all over the place. It went from <1ms to 30ms (WOW I found then issue right? mm kind of) After feeling like is struck gold I decided to not get carried away and test different cables, same result. Different computers? Same results. Test on a router that i had laying around? All my pings were <1ms. This tells me that there is a problem with the modem. I decided to call my ISP and request a modem change, this should fix it right? I went to the store got a new modem. Got home and installed it. Tests with a ping from my pc to my gateway same results 1ms-30ms fluctuations, I’m sad. I decided to give this new modem a chance. Took it to my room (no coaxial cable to bring, so this is an offline test and any outside factors should be eliminated) plugged the modem to my computer with a 3ft brand new cat5 cable and ...... same fluctuation 1ms-30ms. I do not understand what’s going on. I tested everything and even swap modems and the problem is still there. My speed and delays are fine but there is jitter in my connection and cannot play most online games without lag spikes or rubber banding. Someone please send help! I finally got my ISP to put their engineers on my case but have no hope. (This kind of issue is hard to observe from the outside because delay I always expected in the remote tests) My Equipment: Modem/Router combo: Hitron cgn3 Internet package: 250mbps down 20mbps MOBO from main testing machine: Asrock Fatal1ty z170 Feel free to ask and suggest testing methods and solutions. I am not foreign to networking and technical terms so go ahead and talk nerdy to me.
