Hello! I have made a post about my ping spiking before and I got an answer that I can't do anything in my case, but I've realised, that whatever devices are on during the day on my internet don't cause any problems. If its in the evening though, my ping just starts spiking like crazy and I am 90% sure that it's network congestion. I only have 1 cellular tower in my city and my router uses 4G LTE, I know that the 4G can be a problem, but I've heard a lot of stuff about band locking. I am using a Huawei B535-232a router and I couldn't find any way to band lock in the router interface itself, though I know there are 3rd party softwares that can do that for me, I just don't know which ones are safe to use. Any suggestions?
