My router is a ARRIS TG2482AP2-85 that I am using wired-in via LAN cable, for whatever reason it seems that even though I have a decent connection (60mbps down, 11-12 up) I tend to have a very crackling VoIP connection, this happens every now and then in discord, or in the LoL voice server (I know, playing LoL is a nasty habit, sue me) I work from home and sometimes my costumers complain of my connection being so terrible, I switched the LAN cable to another port and that seems to have fixed it some, but it still happens every now and then. I've tried all sorts of things and I'm kinda desperate by now. Any ideas as to what might be the issue here?
