Thanks
I've made the wifi changes. also run a wifi diagnostic upstairs and noticed the neighbors were quite hot on channel 6 so moved to channel 8. this will hopefully improve the wifi signal.
but for the gaming connection. That's a wired Ethernet connection to the modem/router. I got dropped a few times in games last night. My son this morning (not playing anything right now). Will keep an eye on that.
But the dbmV measurements...are those correct? Is the downstream channel voltage not an issue?
