So recently got a 4g modem the ac800. As my nbn is still a while off and I have good 4g reception. I have no issues with my speeds but for some reason my ping will fluctuate wildly. Like from 30's to 400's and back to 30's. And will do this say once or twice every 10 minutes. Which doesn't affect much except when I try to play online games. Has anyone encountered this and is there anyway to stabilize the ping more?
You won't be able to as easily stablise the ping sadly, because 4G requires both radio and physical backhaul. As the amount of users add/remove etc from the local site where you are, the workload changes.
