For the last 6 or so days I have not been able to do any online gaming due to my ping being very unstable and jittery. My ping sometimes is a slightly (barely) tolerable 70-90 with a lot of jitter, and gets so bad sometimes going from 95 to up to 600 in the matter of seconds. I have spoken with my ISP and they have told me as far as they know there is nothing wrong with my internet setup (I have a WiMax setup if you know what that is). I have called my modem manufacturer (D-Link, I have a Viper Dual Band AC1900) many times, and I have done all of the troubleshooting steps they have sent me still to no avail. Last night I turned my modem off for 1 hour, and the box (I don't really know the terminology when it comes to wi-fi setups but basically its the thing that connects my ISP to my modem) for half an hour after the modem. Alot of you will say, 70 ping is fine, thats exactly what my ISP has said over and over, but I can assure you, the 70 feels like 500. My movement dosent register half the time, whenever I click it takes like 2 seconds to actually input it and another 2 just to register hitting someone. On Pingtest.net I get 70-90 ping with 40-60ms jitter. Please help me with this! It is a pain not being able to do this for so long after spending hours and hours on the phone with my ISP and modem manufacturer
